I bought some 40 watt (150 watt equiv.) CFLs the other day thinking they would be better then the 23 watt (100watt equiv.). I decided to look into it more and found out they only have 2000lumens when I could use two 23 watt bulbs to get 3200lumens.

I'm guessing I should probably return my four 40 watt CFLs for eight 23 watt CFLs. That way I could put 4 bulbs on one socket instead of just two and still be under the 100w rating while getting way more lumens.

make sure you use the right kelvin or color temp!

Yeah i actually prefer the 23 watts because i do cab grows, and the smaller the light with the more lumens = best. 40 watt is pushing on size considerations in my cab... go with the 23s they work great

I use 10 of the 23 watt CFLs in a home made fixture. It seems to work really well and when the plants get big enough I turn on the 10 dual tube 4ft flourescent fixtures on the sides.
