600watt is more efficient lumen for watt. Also its considered to be the best light for most situations.i got a whole range of globes from my mate. i have a 2x3 grow area with 8 pot plants
what would be the best globe to use a 400 or a 600. Will the grow speeds be any different between the 2 globes or would i be better saving power and going the 400W
Well said, if I could rep you again I would .600watt is more efficient lumen for watt. Also its considered to be the best light for most situations.
im not here to argue but a 600 is hotter than a 400 and a 600 is a waste of light and energy in that space....... thats truth, you may get more bang for the buck but its worthless if you cant use it and the extra bang will be wasted in that room. a 400 is all thats needed. your right every situation is different but a 2x3 room is still just a 2x3 room and only needs a 400wThe 400w might prove to be too hot for that small of an area unless you got good ventilation. Generally speaking, the 600 is a much better bang for the buck but every situation is different.
