The standard high-pressure 300 to 500 watt work lights are very inexpensive $ 16 to $ 49 at Lowes etc. The color value is between incandesent and sunlight. They are physically hot but come with tripods. Painters work lights the clip on type are $ 8. If you look around flea markets you may find folding tripods with a top that takes the place of the clip. You might find the old spun aluminum reflectors that are 12" to 14" dia. They can be fitted to a new base and 300 w bulbs. I have considered standing fluoresent fixtures on a base for general lighting. They have a color temperature similar to sunlight, maybe more blue that can be either filtered or PS'ed. Misha comments on dimmer use which will move color temperature toward red. Since lumens varies with the square distance it is easier to use distance. Another place to look for lighting would be old theater lighting. Both floods and spots are already fitted for gel filters. They are heavy but can be reclaimed and refitted for 110v standard bulbs. For bases you can fill plastic milk jugs with concrete and stick a piece of conduit that lights can be clamped on. If they are 6' high you can use standard clamps for making setups. Happy hunting at the hardware! Bill
