In today's economy it's critically important to get the most you can for your purchasing dollar. So there's no sane reason to over pay for 50w Xenon when there are lots of them for sale on eBay. Plus, eBay is one of the largest and most trustworthy online shopping sites in the modern world. This site is sanctioned by eBay to help you find the 50w Xenon you are looking for and show them to you. If you don't see the 50w Xenon you are hunting for below. Use the search function on the right to find the variety you want.
I have a basement full of 50W Halogen Recessed lights running on 120V through several dimmers (controlled in sections). Only problem is that they run incredibly hot, while the rest of the house is nice and cool the basement is running like a sauna. I'm looking for alternatives and so far I haven't found anything that would really solve the issue. I really don't want to rip up all the lights to replace them with something else. I've looked into GU10 versions of LED (3-6W, expensive, tall, not dimmable), CFL (~11W, tall, not dimmable) and even Xenon Filled bulbs that promise to run cooler but I haven't found any real data supporting it. I'd like to keep my dimmers if possible but I'm open to other suggestions. Even though I found dimmable versions of LED and CFLs, most of them are too large to fit in the standard housing (Catalina Lighting Recessed Housing) or only are available in 240V versions.
The thing about LEDs is that they can last as long as100,000 hours, this is usually about 40,000 hours realistically, run a lot more economically, and cooler. To really get a design idea for your lighting you could find a consultant @ bigbullsboomland@yahoo.com, Bill is a national rep for several companies. Another thing to run the current cooler would be to rewire at a higher gage. It looks like the equivilent light of a 35w is the best you can do with the LED. These are available, new product development is working on what you are talking about, but the size (GU10) is a product in development right now, I will check another source. Replacing with LEDs will give less light but cooler. To replace with CFLs I found a dimmable product from a different manufacturer. A 23W spiral that replaces a 100W incandescent, 1600 Lumen output, dimmable. 5.1 inches long, 2700ºK. Compare that to par30fl50 Halogen with lumen output at 660 lumens, there is your animal! Up to 3x as bright with half the power and not as hot. If you are looking for color rendering index, there is a florescent out there that produces a 97%, but in a fO32t8, which would mean that you would want to have troffers.
