Re: [Green Tech] LED Bulbs + Totally Enclosed Fixtures + Cold Winters

As a CFL gets older it won't start as well as when it was new. Add additional obstacles like low temperatures and it may not start at all.

LED lighting is a good choice for cold outdoors.

Meh, they cost me 2$ a bulb at Costco for 23W (1600 lumen).
Good luck finding 1600 lumen LED bulbs anywhere near 20$ (10x price of the CFLs I buy).

However for Lurch77, since he turns them on only when they are in their yard or guests are arriving, then LEDs are worth it, though incandescent might be just as good, considering there is no need to conserve energy for a lights you use less than 1h a day on average.

I hope you speak of cold cathode CFL's. Most people don't even know there are different TYPES of CFL's they can purchase. They just think all CFL's work the same. :P

Probably. I bought them at Costco and they are rated for outdoors use in winter.

These LEDs are 850 lumens. I paid $15. So they are not that cheap. That is for sure. If initial cost is an issue then LED is not a good choice. But if you read my posts in this forum, price is not my only concern. These bulbs are made in the USA. I like that, and will pay a slight premium for it as long as the product is quality. Which I've found these bulbs are.

Walmart has recently committed itself to aggressive pricing on LED bulbs; 800 lumens would be typical. I've seen LED flashlights that would throw a beam a mighty long way and practically blind you in the process, so I'm guessing that the real limiting factor here as far as cost and brightness go isn't the LEDs themselves, it's the electronics that you need to step-down and regulate the AC line voltage.

LEDs might very well be a cheap and near-perfect match for DC systems like solar. In fact, I wouldn't be at all surprised to soon see new homes have their lighting systems wired up directly for DC, with AC used for everything else. Or at least to have some shared AC-to-DC conversion systems, maybe at the fixture level. This would no doubt eliminate at lot of the cost of the electronics for each bulb.
