BLV and Ushio are basically the same. If you need good growth, take BLV 10k, or better yet, Aqua Medic Aqualine 10000 150W 13K. However, you will still need to supplement with some actinic light.

Here is, by the way, a reference table of PAR levels for various lamps.

Thank you for the advice. I have already ordered a Giesemann megachrome coral for myself.
