round about gues of how many lights can be supported

i was wondering how many cfls could be support by one regular outlet and is is dangerous if the cfls are touching a little cause if they dont make a lot of heat wouldnt they be ok then thsanks

common sense, and prob read the breaker. Cfls literally you could do tens of. but no touch. no warmth. In ca we get grow fires all the time. idk what they did, but, bet it was more than cfls.
