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.

Yes, but the NEC might say otherwise

and 207/120 = 1.7A

No, they'd all be in parallel.
See the heading "Parallel circuits" in

What is the final application of such a setup? Extension cords are not approved as permanent wiring methods ....

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.
