High, I just finished my first real growroom and i have 4 42 watt CFL each puts out i think 2600 lumens . Thanks,
Color rendering is a little lower than you would have if they were daylight bulbs, but since the lumen output is about right they should work. Just not as good as daylight for seedling and veg. Maybe someone with more knowledge will know more.
soft white...., i want to say that has a bit of a blue spectrum to it but not to much depends on the bulbs manufacturer, if its growing your seeds than your fine otherwise consider a cheap 100-150 hps security light from home depot or lowes for like $50-$100
