• LED lighting

  • George5104

Since, in addition to super knowledge in chemistry, I also know how to create short circuits in the electrical part, I would like to ask the experts on this matter: Is it possible to create a kind of cheat sheet on making LED-based backlighting/lighting? For example: 3W diodes, 50% white with a wavelength of XXX, visible in the marking as ???, 40% blue with a wavelength of XXX, UV - 5%, and pink/red - 5% of the total amount. Drivers are needed for them. An aluminum heatsink is required. A reliable fan is needed for it. Wire (with a diameter of F), thermal glue. How to choose all this correctly and, to begin with, what and with what characteristics should be looked for? Where are reliable sellers? How to calculate and connect everything correctly?

Thomas

It's still a bit early to write cheat sheets on LEDs. Everything is in the experimental stage, and the industry of the crystals themselves is developing very rapidly. Right now, some quite interesting Cree XM-L diodes have appeared. I bought them for my underwater video light, and they shine very well! I made a lamp for my frag tank using 3-watt diodes: 50/50 white Cree and blue, plus a couple of UV ones. I really didn't like the light; the flickering was so bad it hurt my eyes, so I took it down. I powered each diode through a driver. I used these types of diodes and drivers: 8a29#ht_2777wt_907 3b69#ht_1535wt_907 I got everything on eBay, but from a different seller.

Justin9867

Well, that doesn't mean that choosing and combining things becomes uninteresting. I wouldn't want to make a pure LED lamp right now, but I would be happy to craft a compact and sufficiently powerful backlight for my aquarium. [OFF]Where did it go? If there are thoughts about selling it, can you send the details in a private message? [OFF]

Raven7170

There are many topics in DIY about ice lights right now. With links, diagrams, and insider information. If anything is unclear, you can ask the author directly. I've been looking into this topic for a while as a primary light source in a nano tank, but LEDs are developing so quickly that it's hard to find a decent manual.

Tracy

Well, I'll start gathering information on my own, and then I'll share the results. I read about the logo topic, but people didn't elaborate on the selection of drivers, for example. Why do blue ones need certain drivers, while white ones require different ones? Then they somehow mixed and matched them... Maybe I should start differently: Where can I buy aluminum radiators? (only at radio markets?) Are these used options or is it a mass-produced item? Is a size of 27 (28) * 3 cm a normal option for placing and mounting 3-5W diodes?

Ryan

Yarik, if you suddenly decide to do something, you can get advice from Rey (the aquafan) and Vadim the bucks. Rey might even be able to whip something up for you. As for myself, I don't even consider it. I wasn't thrilled with the DIY light/luminaire that Rey showed. Plus, the price is quite high. He spent about 1000 on a 20L aquarium for drivers, LEDs, radiators, etc. But I'm sure someone will say that LEDs shine just great. And there's no arguing about that—LEDs are different, and their settings are different, etc.

Adrienne

We need to wait a bit longer for the ice. The ice itself is expensive, and I don't see any particular advantages yet. After some time...

Catherine

It's a bit early to call us "dinosaurs." For now, to equivalently replace 250 W of metal halide, you need exactly the same amount (250 W) of diodes. I will become a fan of LEDs when two conditions are met: 1. The luminous efficacy per watt exceeds that of metal halide (currently, it is the same). 2. Crystals with a power of more than 50 W become available (not matrices, but crystals). I didn't like the large number of point light sources; there was too much fine ripple. I believe these two points will become a reality in the coming years.

Rick

Here’s a good link on DIY that explains everything about drivers, types, and power calculations.

Wendy2244

I also have glitches with the codes. As for - Here is Karen's topic about the actual production of a lamp here is his topic about making drivers independently here is his topic about a controller for the lamp Here is Oleg's lamp (Oleg_Il) Here is an option with Chinese diodes here is another option Notice that at the end of each topic there is a real product. What more do you need? It's foolish to expect a separate manual. You need to spend a couple of evenings reading everything, drawing conclusions about whether you need this or not. P.S. For example, I ordered his controller from Karen for my modification.

Sara4035

I'm not opposed to it. Of course, you can replace 1220W with 460W, but the light output is reduced by half (you can't argue against the datasheets). The other question is whether that's enough for the corals (maybe they didn't need 1220W at all). I personally want to add 3W LEDs as supplementary lighting when the metal halides are off (there are issues with cooling), but I don't consider them as the main light source. For a nano tank, LEDs are just what you need. You need about 4-8 of them. It creates a beautiful glow.

Cheyenne2747

I suggest the following light: CRI MinFlux Cold White LXML-PWC2* 4500K-10000K 60 70 200 Cold White LXML-PWC1-0120 4500K-10000K 70 120 Cold White LXML-PWC1-0100 4500K-10000K 70 100 Which ones are better to choose? 7 pieces fit on the radiator (I calculated based on a 2cm diameter) I'm not asking for color advice, but rather how to calculate the drivers.

Michelle

Do I need special software for this LM3DMX, or can I easily set up three channels? I couldn't find the specifications for them... So, I'm relying on 700mA or 350mA and looking for a driver power of at least 42W or 70W if using 5W diodes. Is it important to have at least XX W or something else?

Monique1236

I added in my post above... About this controller - I won't say anything - I haven't seen it in person. It's worth calling and bothering the sellers. It's in Kyiv, right?

Jamie3553

I feel like being a dinosaur Big, fat, and lazy

Whitney

I visited Rey (a huge thank you), and I saw how the little lamp works with five sets of four LEDs. Compared to the PL 36 lamp, it visually produces light that is one and a half times stronger. As for what he programmed, you can create a real kaleidoscope—choose any color, sunrise, sunset, etc. For now, we decided to stick with 4-5 "gears" with a triple set of LEDs in them.

Crystal4879

Addition = these triple sets of Krishnas, eRZhBi. Maybe it's better to use single diodes instead of sets? What does everyone think?

Tonya

Well, some use RED and GREEN. But still, it's exotic. For corals, these colors are like a stop signal for a rabbit. So the classic LED light is CoolWhite + RoyalBlue + a few UV (420-405nm). Everything else is just a gimmick.

Chelsea

In terms of reflections: We use warmer light for the algae tank. Those who did the lighting for the SAMPA with LEDs used red. But with the algae tank, everything is clear. As for zooxanthellae, they are what give color to the coral. Maybe we should try using RGB (red-green-blue) after all?

Guy

Zooxanthellae are specific algae. They have adapted to the spectrum present at the depth where corals grow. There is almost no red and green there. That's it.

Tina

If you set up RGB, I'm afraid unwanted growths may appear. Why reinvent the wheel? There is experience at the reef center and they seem to have figured out the spectrum already.

Jeffrey

It will convince, it will convince, 10W already exists. Well, not 50, but let them be at least 20W with a luminous efficacy of 150-180 lumens per watt. Then I will get involved (oh, and electricity will rise in price just in time). This diode is already close to my ideal. The only question is how long it will work properly at a current of 9A.

Todd

Why not use LEDs with 10000-20000K? Such parameters in Kelvin are better in the sea, or am I missing something?

Larry

It's not that simple. The color temperature of LEDs and lamps are somewhat incomparable characteristics. The lamp emits a broad spectrum, while LEDs are much more selective. There are no white LEDs with such temperatures (what the Chinese claim doesn't count). To bring the light color closer to the desired one, this is exactly why cold white is mixed with blue or deep blue (Royal Blue).

Alicia5489

The sensor, judging by the photo of Luminos, is the same matrix.

Eric

So what parameters should be considered when choosing LEDs?

Jeffrey2277

Well, formally XM-L is also a matrix. This does not diminish their merits in any way. The important factor is the output in lumens per watt.

Karen81

Well, there are a lot of parameters. The important thing is the output, i.e., the efficiency in lumens per watt... Although, I don't consider myself a guru and I'm not ready to give any recommendations. :-)

Christopher1774

Does lumen watt refer to all colors (white, blue, red, UV)? Is the quantity of watts or lumens more important for our aquarium? If it's lumens, then I understand that they can be achieved with a higher wattage. If so, what is the best amount of lumens per liter (or the optimal minimum)?

Nancy758

The more lumens, the better, as I understand it.

Catherine6534

I think so too. That is, the lumen/watt parameter is important to achieve maximum brightness in lumens within reasonable sizes, scales, and cooling methods.

Gregory9432

Can you buy something like this somewhere? And what parameters should I pay attention to? How many Kelvin and Lumens should it have? So far, the maximum I've encountered is 6500K.

Curtis

LED - rt_order "Water" advertisement was brought in today.

Justin

In the outskirts, no one talks only about lumens. Only by reading reviews from owners on the RC and analyzing what I've read can one draw a conclusion.

Daniel4967

Not a serious thing at all. Just for some extra light.

Monica

Unfortunately, they don't have 1.5 meters, I would have bought it just for additional lighting... I was interested in something like this for additional lighting... unfortunately, it's expensive...

Colin1418

Riusha, I agree with you on some points and disagree on others! We produce this lamp and are ready to delight serious aquarists with more advanced lighting solutions. However, I will say that undemanding soft corals feel fine under this lamp. Currently, at the ZOO VET EXPO exhibition in Kyiv, we are showcasing a prototype of a "serious" lamp based on Philips rebell crystals, specifically for small marine tanks – we are studying the demand, so feel free to come and take a look! The lamp is quite capable of supporting most LPS corals – I checked it myself.

Michelle

Yura, I didn't know that you produce it yourself. Honor and praise to you. Seriously. In the promotional video, it is installed on a freshwater aquarium. I think that's the right place for it. It's just not possible to get a decent output for saltwater with 3258 SMD diodes. However, there are some advantages; the cooling issue for such a fixture is almost nonexistent. And the 12000k figure is debatable. You simply have Cool White diodes. According to the specifications, they are 6000-7000k. The range is small, with only 3 types of white. I'm curious to see the product with Philips Rebell.

Melinda2740

I ordered a lighting setup with 15 stars, white and blue, which will be placed next to the T5 lamp. I didn't bother with dawn/dusk; everything will be on simple adjustment... If I like the result, I will change all the lights to LEDs... Here are the calculations they made for me: 1b) W - 47 * 15 = 705 2) Profile 1.5 * 180 = 270 3a) Power supply - 48V 135 Watts ~ 300 4b) Drivers for W 30

Debbie3587

And where is he? Show a photo.

Melanie

Stas, then the LEP technology will definitely suit you. 250W power replaces 450W metal halide. "Dilute" it with powerful LEDs and you're good to go. So it's time to slowly say goodbye to MH, although the farewell "will be long and tearful" (I hope I didn't offend anyone).

Hunter1471

And who needs to say goodbye already?

Charles894

Well, probably for those who are tired of MG No, of course, not everything is so bleak (or rosy) depending on the situation... Although it all reminds me of an old story: Cassettes - compact discs Compact discs - flash drives In general, the list can go on. A bit of video from the ZooVetExpo 2011, the company's stand, demonstration of the AquaLighter 60+ lamp.

Randall7906

Explain how to select lighting for a boosted grass tank. With freshwater, everything was clear: watts per liter and the famous models of well-known manufacturers. I didn't pay attention to light intensity during that selection. Now I need to consider it. So, what criteria should be used to choose lighting for a freshwater aquascape? And how is lighting selected for a marine tank?

Cindy

Finally, I am showing a photo of a powerful light fixture for a marine nano aquarium up to 60 liters: It uses Philips Rebel LEDs: 3 Cool White 220 lum 2 Royal Blue 38-degree collimator lenses

Alan273

What is the recommended price for this lamp?

Sheila1322

For the sea, it seems that the spectrum issue is resolved, but let's discuss freshwater, as LEDs have a great future. Based on the general recommendations of 4500 - 6000 K for plants, would it be correct to use warm white or the so-called sunny white? In the Amano mini (no more than 10 liters), I saw about a dozen cool whites + 2 royal blues.

Lindsay

Minimum 800. The lamp is completely waterproof and can be dropped in water.

Lindsey3628

Can I take a photo of the aquarium in the frontal plane? And one more question, how much will such a lamp cost with 2 royal blue, 2 UV, and 3 white lights?

Jennifer9100

I don't know how much it will cost - it's not a standard fixture, we definitely won't be producing it in series. If you're interested, check the topic. I can sell this one, it's just amazing - at the price of the components!

Mark7376

A luxurious lamp, the future is behind it.

Jeffrey496

Good afternoon. Could you please tell me how your experiments with LED lighting are progressing? I am interested in lighting a 400-liter aquarium, or have you not yet advanced to such volumes? If possible, I would like to know the price and see photos or videos of your products!

Mark7376

Thank you, Tolik, for the information, but I was talking about full lighting for the aquarium, for example.

Johnny

Are you sure you didn't mix it up? 1.5 W per LED in the strip is not realistic, especially for 380 grams with the driver.

Jennifer5784

The tactical and technical data is missing. I will call the store today and clarify the situation once again. Then I will update you...

Eric5208

1.5 W for the strip is not realistic, there are weaker diodes... but a lot.

David3217

Guys, you are right, there was a mistake with the tactical and technical data, the store apologized and sorted it out. The breakdown is as follows: for one linear meter of tape, the voltage is 1.44 watts. This is for 60 LEDs. Thus, one LED has a power of 0.42 watts, right?

Joshua448

I think 1 diode will have 0.024W then.

Raven7170

In my opinion, the quality of lighting is not always determined by power. For example, an electric heater consumes 1 kW but doesn't emit much light... The same goes for light bulbs. A 40 W energy-saving bulb is much brighter than a 40 W incandescent bulb. For light, physicists have quantities: Candela () Lumen ()

Teresa

Can someone make an LED or LED+T5 light for a 400-liter marine aquarium with soft corals and LPS (large-polyp stony corals) to meet certain watt/liter or lumen/kilogram ratios? I'm not familiar with these measurements... If so, what is the price and can you provide photos of previous products?

Jasmine

The final result is important to me.....When I saw how these LEDs shine, I made the decision to buy them without hesitation. Their light suits me just fine, although there are brighter ones, and the price is accordingly.....

Theresa5149

I can do it, but the price... We need to use proper diodes like CREE, which need to be ordered... in general, the cost will be very, very high... On LL, there are no problems at all, here are samples of the work.

George5104

What is this new S&M LED+T5? I think it's something incompatible, unless the LEDs are used as night lighting. As far as I know, no one is making fixtures with LEDs yet; Rey makes stars for profiles and controllers, but he doesn't deal with the housing and finishing of the fixture. So, it's either DIY or getting ready-made Maxpert, Key, or Pacific Sun, but the prices there leave much to be desired.

Ryan2281

Look and contact me for production.

Jade

Hello, the sadomasochism comes from the fact that the aquarium was originally not designed for the sea, and there is almost no place for proper lighting. It's barely surviving now, and I'm thinking about what to replace it with. Please advise if you have a solution... I am attaching a photo.

Justin

What is the price, power, dimensions, how hot does it get? I understand that cooling is not provided? Or is it available as an option?

Chad

Didn’t understand? Please specify your questions! Why is cooling not provided?

Carrie1606

Price, dimensions, power, and other parameters for this light fixture. Automatic temperature tracking when using the cooler - as stated on your website, how much does this option cost?

Luis3725

Well, why BDSM? ndora-xm-ultie-fixture emid=55 Let's look at Pandora.

Sheila

There is a choice here - the same san-san, T5 from A, and for LEDs - "give" or ready-made - depending on desire and capabilities. For my new one, I'm making a DIY LED, but without a controller - I've seen the logo, plus the new aquarium is 25 cm shorter than the old one - the light needs to be completely changed. Thank you, I haven't seen anything like that before. The T5 seems to be just for additional lighting, while the main source is LEDs, even in terms of power, that is, it's similar to MH + T5, where instead of MH there are LEDs.

Joseph591

Led+T5 will be available soon, it is still being tested.

Mario

Hello, I would like to know the price, dimensions, and power, even approximately, for a 400-liter aquarium with a length of 1200 mm and a height of 700 mm. By the way, the fish I bought on Friday arrived fine, thank you.

David2398

Night light. "Moon". Or how the LEDs shine, which were mentioned in paragraph 61.

Joseph

One fan blows air in, the other pulls it out. Under the lid, there is a 2mm acrylic sheet, and water evaporation is minimal. The acrylic will need to be replaced with polycarbonate, but everything is fine as it is—there are no signs of overheating or corrosion.

Michael

Yes, I'm not arguing, I have an 8*39 T5 myself (a mix of KZ, ATI, and Aqua Medic), but the fixture has become unusable, and I want something newer and more serious! As for heating, the temperature reaches up to 29 degrees, with evaporation of about 4 liters per day. Overall, T5 is not a bad option; if there were a decent fixture around 400 watts that would fit my parameters, I think the issue would be resolved.

Kendra2262

most likely it will look something like this... in the photo - 4x39W + LED (90x38x8 cm) I can't say the price yet...

Lindsey3362

The size of the class is just what we need, we're waiting!!! And how much is the LED power or how will you order it?

Michele

Hello, what can anyone say about this ice: 1) Color: white 2) Color temperature: 6000-6500K 3) Luminous Flux: 7000lm 4) Current: 3.0A 5) Voltage: 32-36V 6) Power: 100W 7) Size: 56 x 53mm

James5103

Well, it's better to ask about that on "logo." I'm curious, what will this heater need to be cooled with???

Daniel9952

I found it from the Chinese for 27 bucks. This is probably the new generation of ice axes that Stas Alpin was talking about. MG is nervously smoking on the sidelines.

Joshua9340

it's very cheap for 100W, even for Chinese ones, and as they say, Chinese ones tend to degrade significantly and should ideally be replaced every 1.5-2 years. here's their average price, and for 27 euros, it's more likely 30 or 50W, but not 100, although who knows. and if you buy, it should be "Cree" ones, but their price will be even higher, and cooling such "heaters" won't be easy.

Joseph9057

dealextreme is a well-known dealer. On SanSkye, it's 27 dollars; I checked, it's exactly the same. Cree is also available there for 3-10 dollars each, depending on the power, but up to 10 watts. I just thought it might be better to install one 100-watt diode than ten 10-watt ones.

Ryan2281

Yes, half of it is messed up, and the prices are almost all twice as low as on other sites. For the 3-watt "Krii," it says 5 watts, and with parameters like diodes costing 10 units, but they have it at 3.46??? Here is the site from where half of the "logo" is taken for the diodes.

Sheila1322

Please tell me where in Kyiv I can buy components for such a light. It looks like everything here is soldered with wires; I think I can do it too, but I don't know what to use for soldering. The light is from the logo; here is the topic.

Jessica9188

There was already a link to the Aquafan Forum here. I think we can negotiate with the rig. He once offered me a ready-made design; I just wasn't ready yet, although I have some ideas.

Melanie

found here such: Super powerful LEDs and Edison-Opto matrices 3W LED, S series, 120 degrees, cool white 6000K, 190 lumens, 3.6Vx0.7A 3W LED, S series, 150 degrees, blue 470nm, 30 lumens, 4Vx0.7A can we solder light from them? huh?

Jennifer7159

I'm also looking for diodes for the mini, but it's not so easy to find the right ones here. 6000K might be a bit too low. And blue diodes are supposedly needed in the 420-460 nm range?

Carrie1606

6000K might be a bit low, or maybe not. Different specifications and different manufacturers. I bought 30000K from the Chinese. They are quite nice, white. Regarding blue, the shorter the wavelength, the better, of course, but you can manage with 470. It will just be blue without fluorescence. A better option is a 3W LED, S series, 150 degrees, ultraviolet 400nm, 400mW, 4Vx0.7A. How much do they cost there? There are datasheets, but I didn't see any prices.

Jonathon8514

25, if the seller and the buyer understood each other correctly.

Tina

for example, Cree Cool White is a favorite and proven option but at 10 USD: Typical CRI for Cool White (5,000 K – 8,300 K CCT) is 65. What does 5,000 K – 8,300 K mean and what does it depend on?

Melissa3200

there are half without stars, only ice. there are different krii, what letters are there?

Stephen5841

"There's half without stars, just ice." That's good, I bent the contacts. And I glued the diode directly to the radiator with thermal glue. Where can I buy the right Cree in Kyiv, and for how much? Thanks.

Alec9378

Usually, the diode is small, and performing these manipulations is not very easy, so it's better to buy it on the star - less hassle. And the Kree don't have long legs at all. I don't know about that. You can try at the Kharkiv cosmodrome, but the prices there are also not low in retail. It's cheaper to buy the radiator here. ... Diodes are sold by Ray on Aquafanat - three LEDs on a big star, he's from Kyiv.
