THanks for the info Dougal. I can't believe I didn't think of the Y adapter thing, pretty good idea. I think I will get two of those bulbs and a Y adapter and see what happens. The cost of 2 of the 6500K bulbs is about the same as the 2700K so I really have nothing to lose. I only have like 4 plants at a time in veg, so I have enough sockets to do one light per plant, so each plant is getting the 4200 lumens by itself.
MasterKushy Reviewed by MasterKushy on . Lumens vs. Kelvin? Is it more important to have more lumens or a good kelvin temperature? I have been using 2700K 68W (300W equiv) CFL's that are about 4200 lumens, but I found some 35W (150W equiv) bulbs that are 6500K but only like 2200 lumens. Which would be the better buy for vegging plants? Rating: 5
