idk i think they have different heats
if you dont have alot of space
you can buy the cords with lightbulb ends on it
and get the Y adapters that make 1 light socket into
2 , those are made for celing fan lights i think
and you can run cfl bulbs , the 100 watt ones use like 20 watts
and they make giant ones too lol and last for 7 years
pit6ull420 Reviewed by pit6ull420 on . CFL Question... Does anyone know.. - does it matter if you dont get a blue spectrum cfl for the vegative and a red spectrum for the flowering because on my budget i was only looking to get the one cfl lamp at £20 and one cfl reflector at 50ish pound. So does anyone know if it matters that i dont get both spectrums, and if i should get both why do i have to.. Answer back please... Peace...... Rating: 5
