The Clamp light vs. Worklight vs. PAR38 Cans

Alrighty then, Ryan and Potato, you guys are making sense. I'll at least stick with the household incandescents for the initial setup and maybe experiment with other stuff later on.

So I'm heading to home depot next week to pick up some aluminum sheets and try make some diy barndoors for the scoops. I'll post my results...I'll also be building more in-line dimmers for this and likely put the 6-8 dimmers all in one housing. Now I've got to do a little reading up on how much amperage is safe per household ac plug...hopefully i wont blow anything...hehe.
 
Typical household circuits are 15A. You shouldn't be anywhere near that for a small set up like what you described.
 
P = I x V

P is power which in this case is measured in watts, I = Current in amps and V = voltage So;

Watts (9x150) = I x 120 (US voltage out of a standard household outlet)

1,350 = I x 120

I = 11.25


I didn't realize you were planning on 9 150W bulbs. Do you really need that much light? I thought this was a small space.


EDIT: If you're planning on a couple of those being used to light up your background, you might go ahead and use CFL's instead. You shouldn't really need to dim them after you get them set up how you like. This will help keep the heat down. With that many lights it will get hot down there. In fact if you decide to go with a standard lighting set up for all the lights, you can skip the dimmers and use all CFL's (or mostly CFL's). If the segments you are shooting take longer than an hour or so the heat from the lights will really become obvious. Dimmers are convenient, but you can always move the lights farther away or apply diffusion. It's hard to get everything you want on a budget.

Yea, I think you're probably right. Plus, power management would be really simplified.
