Re: Do you use Tota Lights?
It is possible to use a suitably sized dimmer with a Tota-light.
Like all incandescent bulbs they will shift towards the warm side in color temperature as they are dimmed. Sometimes this shift is used for effect (art) and sometimes it is corrected for with various densities of CTB gel. Using lower wattage bulbs, Neutral Density or diffusion gels and adjusting the distance to subject will change the output without changing the color temperature. Often combinations of these techniques are used. Don Bachmeier Lighting Applications Spec. Lowel Light |

Re: Do you use Tota Lights?
Don, as far as the color shift is concerned, can this be resolved by simply doing a manual white balance when changing to a dimmer. Also, when you say a "suitable sized" dimmer, is there a certain specs that I should be looking for?

Re: Do you use Tota Lights?
I have 4 of the Harbor Freight speed controls. They were great for a while but then one went bad and I'm finding some lamps start buzzing when dimmed much below 90%. One of them is a Tota with a 500w halogen. It may be related to the age of the lamp and I don't know if a proper dimmer will operate better. I also had noise in my audio from those dimmer when I joined two XLR cables together. The metal XLR connectors were picking up the interference.
http://www.dvinfo.net/forum/all-thin...ighlight=audio I didn't get a chance to try the remedy so I don't know for sure if was the Harbor Freight speed control as a dimmer. |

Re: Do you use Tota Lights?
I've heard all of those complaints (they do go bad, but as usual, you get what you pay for). Buzzing is often a function of the dimmer quality.
A better way is to use a quality household rotary dimmer mounted in a housing or even better yet, a big ol' variac. But I know peeps around here like the cheaper stuff, and these will run much more money than the Harbor Freight.
