No ground prong, so not the safest but those compact fluorescents draw minimal current.
Compensate for the lack of ground by ensuring it will never get wet, dont use a long extension cord ( shorter the better).
As long as you use it on a circuit that isnt carrying a heavy load already you wont experience any problems.
FunkyMonkey Reviewed by FunkyMonkey on . Need some opinions! I found this today and i bought it, i was wondering if every1 thought it would be safe to run 2 CFL's in it, or if they think its a fire hazzard, theres a pic attached, and it will be attached to an extension cord. Rating: 5
