Update - I added a 65w equivalent daylight (5000k) r30 cfl flood light with $8 metal clip reflector to light my fuge, and still has the cheap 3w LEDs which have some blues. Now instead of watching my cheato slowly wither away, it is growing like a champ. And the bits of keyna tree that I've banished to sump seem to be happy as well. I'll have to try Xenia soon. So I am very happy with this cfl light, total cost with reflector was under $20 at home depot. At this rate, I will have to harvest some cheato in a few weeks for the first time ever. Nirates are zero (or undetectable) and I am over due for a water change, its been over a month since the last one.
