another fuge bulb thread
 

Iven been using melev's 5100k bulb on my fuge for about 3 months now and my chaeto has maybe increased 30% this seems really bad to me considering im hovering around 20ppm nitrate i run it reverse photoperiod . Anyone have any other bulbs out there with sucess ive been reading 6500k is a good choice will i see a difference in this?

Regular old 20W compact fluorescents work for me. Use two if you have a large fuge.

i'm running a 27w 6500k CF bulb, getting good growth

with everything else equal increasing intensity will add chaeto growth.. the LOA floodlight is 65W and 6500K color.

Im with the LOA or even a simple light bulb, my experience was that the more yellow the better the Chaeto grew! I ran a simple shop light over mine and than went to LOA and it was great!

I use two bulbs similiar to the one's Melev uses. The more the merrier.
