you are right tux, my bad. i was in a rush and trying to make a point and misspoke.

how do higher kelvin values mean less lumen output? the color temp is controlled by the gasses in the envelope, nothing more. how can i buy two 23W, 1600 lumen CFLs and get one in 6500K and one in 2700K?

CFL question So im getting 2 150 watt cfl's actual wattage and one in 2700k and the other is 6500k can i use both of these at the same time or do i have to use them one at a time like 6500k for veg and 2700k for flower hoping i can use them both together obviously for the extra lumens. sorry for sounding like a total noob Rating: 5
