A local space has some off-the-shelf 500W halogen flood fixtures (basically the architectural version of the cheap portable worklight) as their only house lights. These fixtures are obviously horribly energy inefficient, burn out constantly, and even have sockets that regularly fail when run 24/7. For worklight purposes, I would immediately replace with LED, but they use these on a dimmer for house lights (although they are often on 24/7). Certainly, they could get different fixtures for "show" and "not show" purposes, but obviously this would require hiring an electrician and adding new wiring (and of course budgets are tight). I see very little in the way of dimmable LED flood fixtures on the market, and none from any reputable manufacturer (at least none that I've heard of), and most anything else seems to be a much narrower beam in comparison to the existing fixtures. Potentially DMX could be added to these locations with less expense, but would still be a little tough for them (and also most of these fixtures seem either pricy or not likely to be designed to run 24/7 for years). Does anyone have fixture recommendations for this application? (Again, the preference is for something directly dimmable, but if it's a DMX fixture, the cost shouldn't be too outrageous and it should be ok to run 24/7).
