you boys are getting ripped off...trust me...i have looked at prices and types of lights for non stop the last 3 weeks..and i am here to tell you...you are buy little cheap ass lights that you will end up needing a whole sht load more of because they are not 100 actual wattages...they are equivelents...they are probably really 13watts or 23 watts...something in that range...its a lot cheaper...TRUST ME...to just buy an actual 150watt CFL off the internet for AT MOST 65$...then this is pretty much the only lighting you would need for a small personal grow
