## Let me know if this is a bad idea...

I really don't know much about wiring and stuff which is the main reason I'm here.

I'm trying to wire 9 150watt-max outdoor lampholders together to hold 9 23watt compact fluorescent light bulbs.

The box that the light come in say do not use more than 25 bulbs on a single 20 amp branch circuit so I figured this would be feasible.

Could this be as simple as splicing all 9 lampholders together to an extension cord?

If my math is correct that would be 207 watts running through the cord.

What worries me is would splicing 9 outlets together make the light be dim or if one broke would they all go out.

Any information would be helpful. I hope there's a way to do this because I think it would be way easier than running 9 trouble lights out to my yard...

It's only 575w for a ~2400w circuit, so maybe these CFLs pull a large surge current on startup. Could this be as simple as splicing all 9 lampholders together to an extension cord? Yes, but the NEC might say otherwise If my math is correct that would be 207 watts running through the cord. and 207/120 = 1.7A What worries me is would splicing 9 outlets together make the light be dim or if one broke would they all go out.
No, they'd all be in parallel.
See the heading "Parallel circuits" in

It's going to be a portable yard light that I can use when working outside.

I know I could go get an el cheapo hallogen light to move around but I already have all the supplies to make one myself. Therefor I wouldn't need to spend any cash.

The extension cord is rated at 13A 125V 1625W.

Think I should leave the plugs at the end or should I snip it and end it with a lampholder?

Thanks for the info Yoyizit.
