Halogen brightness for video I'm trying to get an idea of the brightness of halogen lights before I go and buy any. I'm going to be producing a music video and for some indoor scenes I'll need lighting. I'm on a small budget unfortunately so hiring hundreds of dollars of lighting is not on the agenda.

I was planning on getting some cheap work lights of 250W or 500W but I've heard people say that 500W lights are actually very bright and get rather hot.

If I was looking for an exposure at 1/50th of 1/100th (for 50fps shots) at f/2.8-4 at around ISO 100 or 160, will a 500W light be too bright? I obviously want the ISO to be as low as possible since I'm working with an APS-C DSLR, not a dedicated cinema camera.

I do have an ND4 filter on hand. The only remaining issue would be controlling the light from the work lights.
If anyone was curious, I managed to pick up a 400W halogen work light (supposedly delivering equivalent to 500W) and the exposure within a few metres (3-4) was spot on. I also bought a 250W halogen that I would probably use more as a fill light as it's a stop or so darker.

At f/2.8, ISO 100-320, 1/100th at 50 frames per second, the exposure on the histogram was pretty well on the money.

And the light cost me all of $20. I filmed it at 3000K (approximate temperature of halogens) using the CINEMA pf2 profile on my Canon EOS 60D. The profile produced an almost completed colour grade.
