20 watt Coralife 50/50 bulbs

[jeremyhaas]

I am using these in my 10 gallon. They are 50/50 bulbs, 20 watts each. Half 10k/Actinic. I am using these over my 10 gallon tank and if I need bigger lights I will get them but if these two 20 watt power compact bulbs will be sufficient enough for low light/medium coral I will stick with them.

Bumping an old thread b/c I have the same question.
Anyone with experience using these bulbs? I plan on using 1 over my 5g nano, but I'm not sure if that's enough to keep zoas and rics happy.
