Re: [Frameworks] Make shift lighting-installing a dimmer to work lights.
Thanks guys, really appreciate your help on this!

Re: [Frameworks] Make shift lighting-installing a dimmer to work lights.
The only real reason for dimmers is to perform light cues, as in a stage production. To simply adjust intensity on the subject, just move the lamps closer or farther and let the inverse square law adjust the illumination. If you need to have less bright lighting in a fixed smaller space, the easiest way is to have a selection of different watt lamps (i.e. what muggles call 'bulbs') in your kit that you switch out into your instruments (i.e. what muggles call 'lamps'). If you're basing the kit on on hardware store halogen utility lights, these generally take a generic size halogen lamp, that is, you can probably get lamps that size in 250W, 300W. 500W etc. Easier and cheaper than trying to rig up dimmers. The dimmers also create a lot of counter-EMF and can play havoc with electronics plugged into the same circuit. An amazing resource for specs and cross references of projection and studio lamps is www.donsbulbs.com. Don's prices are competitive on some items, not on others, so check the other online sources such as top bulb. If you're shooting video, you can, of course, put just about any kinds of lamps in your kit as long as they match without worrying about color temperature, since white balancing the camera will take care of that. For tungsten film, of course, you need 3200K. If you do have hardware store lights with the protective grids and glass shields in the front, take those off. They just add weight. Mever touch a halogen lamp, hot or cold, with your bare hands -- the oil from your skin will stick to the glass causing uneven dispersion of heat, shortening the life of the lamp. You can affix 'softspun' or other non-flammable diffusion material to the from of the instrument with wooden clothes p[ions (the spring kind). If tried fitting barn doors to hardware store worklights, with not very good results. If you need to control the beam, the best bet would probable be making some kind of jury rigged snoot out of an aluminum clothes dryer vent, aluminum roof flashing pieces, held together by aluminum tape or maybe pop rivits. A possible upgrade for a DIY light kit is to order the mount parts for a Lowel V-Light, I think it's called a Lowel link (??) which will make the light easier to position and provide a spot to attach an umbrella. djt On Oct 28, 2011, at 10:49 AM, Kevin Timmins wrote: Hi, I'm trying to make myself a frugal 3 point lighting system with one 1000w work lamp and two 500w work lamps.
