Not trying to hijack but......

I was in Menards the other day and was wandering around the lighting section. I came upon some HPS bulbs and was looking around. I found some bulbs where the wattage went from 35w up to 250w I believe.

Here is my question....say I have a friend who used 6 - 4ft. flouros for their last grow. Well, I was thinking he could buy 4 - 100w HPS bulbs to use instead. I asked the lady working and she said the bulbs can be used in a regular light socket. Being how they are only 100w I didn't see why not.

Cause obviously 4 - 100w HPS would put out more lumen's than the flouros, correct? His basement stays cool and ventilation is good. The area is 5ft x 2 1/2 ft and about 3 ft. tall.

What you guys think since we are on the topic?
Lit Up Reviewed by Lit Up on . 600w hps + small closet = no go? in theory would a 600w hps (95,000lumen output claim) in a closet 3ftx3ft x9ft*heigh* be a major fire hazard or damage anything? Also, ventilation wise the intake should be bigger then the exhaust or vice versa. Last but not least could tinfoil be used to line the walls without damaging vegetation with intense light spots until mylar can be obtained? Thanks Rating: 5
