200 W?!?!

Post #359,021 by Another Scott 6/16/12 8:10:05 PM Reply	200 W?!?! Zooks man! That's a lot of power for a light fixture, especially in a home. Incandescents are terribly inefficient light sources. Most of the power is given up as heat. If you really want ~ 2500 lumens, you should think about something like this - http://www.amazon.co...ers/dp/B00774Q6E6 2500 lumens at 28 W. The power savings would be significant. Single LEDs are up over 254 lumens/watt now (at low power), and being improved all the time. Most halogens are less than 20 lumens/watt. I keep waiting for reasonably-priced LED lamps that have the qualities of halogens, but they're not quite there yet. We're using compact fluroescents and living with the lack of dimability, etc., for now. One gets used to them (and we haven't had any overheating/fire issues like malraux mentioned, but YMMV). Cheers, Scott.

No, I'm going to wait a while before investing in those to see how it shakes out. They all require replacing fixtures too. I have used curly fluorescents in some locations for at least 15 years, but they are locations where light quality and dimability are not important to me (5 locations). But yes, 200 watts per fixture. Kitchen, office, bathroom, bedroom and dining room. One ceiling fixture in each room (hanging lamps in the dining room). I consider that the bare minimum illumination to work in those rooms (and the ceilings and walls are all painted bright white to maximize light).

Post #359,025 by Andrew Grygus 6/16/12 11:12:39 PM Reply	Well, I also have . . . . . another ceiling fixture with a curly fluorescent in it, but it's rarely turned on because that side of the kitchen is storage. Since walls, ceilings and cabinets are bright white it gets enough light. I turn it on only when I need to read small print at the phone.

Go sit under one and read a book for a few minutes or work on some tight electronics and you will see the benefit. You too Box. I'm thinking of putting one over the fish pond for my evening entertainment.

Post #359,033 by crazy 6/17/12 8:31:24 AM Reply	None No dimming. And warmup is about 5 minutes. And yes, they need a special ballast. They are not a general replacement as people are trying to get you to do. I'm simply pointing out there are non-standard light sources that most people don't deal with, yet the spectrucm they provide is far better than what most people live under. In this house, the guy went all out on a variety of lights, so I got choices.

Florescents and leds have their place but a reading light or a workbench I prefer to see without strain or burn Any opinions expressed by me are mine alone, posted from my home computer, on my own time as a free American and do not reflect the opinions of any person or company that I have had professional relations with in the past 55 years. meep
