Our experiences with LED light bulb replacements

<< < (10/13) > >>

longrun:
There's been some lame arguments that the reduction in power consumption from CFL bulbs results in less overall mercury being released into the environment in areas where coal-fired generators are the norm - because less coal (which also contains mercury) gets burned. But that sounds more like an industry thrashing around to find something - anything - to throw up against the fact that no level of mercury exposure is ever good for us.

I totally disagree. Less mercury is less mercury, and CFL's are easily recycled where I live.

Been hunting for an LED light that can be used on [covered] front porch.  Needs to be reasonably weather resistant, if not weatherproof.  Also would be nice if it had built in light sensor so I don't have to remember to turn it on - or off! - but I might be reaching a bit there  :-\.  Corpus, while comfortable, is not a shopping metropolis  :tellme:, and I'm not having a great deal of luck searching online.  Any suggestions?

Lowes has a couple of variations on that theme that screw into the bulb socket, and then the bulb screws into them:

I've had similar motion sensitive widget on my front porch for the a few years now. Walk up, the light comes on. Walk away the light goes off in about 10 minutes. And the best part is, I do nothing. :)

Might be useful. Very informative notes here from Michael Herf - the guy who I gather is the author of f.lux (which I have used for a while now) and the original author of Picasa: - notes on Full Spectrum lighting.

mouser:
Just reporting in that I'm still quite happy with my switch-over to LED bulbs.

A few observations thought:

1. I've had quite a few go bad.  CREE (manufacturer) replaced them though i had to pay shipping to send them the bad ones.  They seem to go bad in certain fixtures and not others.
2. I have a couple of Phillips ones that do a good job of lighting, but make a buzzing noise.  Very annoying.
3. Soft White is the only way to go, the cool temp bulbs get annoying very quickly.
