It's a duel bulb 'H'
fluorescent fixture. Each bulb puts out 6500k at around 3400 lumen, so 6400 lumien total output. I got it because it's compact and I thought would be perfect for a single bucket, but I'm kind of regretting that now. Looking around, the
bulbs are hard to find and more expensive than T5 or T8s. Live and learn, I guess.
Just in looking the algae seems to go down a quarter to half an inch or so. I'll try spiting it open and getting the little guy into a new rockwool today. It's too late to move it outside and expect it to produce, so may just keep it going inside and see what happens.
Thanks for replying Stan. If I decide to keep it going, I may start a thread in the blog or setup forum and keep y'all updated.
