LED Light Bulb Discussions
I've been considering replacing 50W PAR20 halogen bulbs with 7-8W LED equivalents for the pot lights in our high use areas - kitchen/dinette area, possibly a few others. For the kitchen at least I figure those lights end up being on for an average of 5-6 hours a day easily (maybe less in the summer but certainly most of the rest of the year).
If you do the math and use an average cost of $0.12/kWh, that ends up being around $13/yr per bulb whereas the LED equivalent would only be about $2/yr. With the good LED bulbs now costing around $25-$35 each it only takes 2-3 years for them to pay for themselves, and they will supposedly last 10+ years (25,000 hours).
I've been looking at some of the newer ones available and the Philips bulbs seem to be some of the better ones. Does anyone have experience with these or other PAR20 LED bulbs? I'm mainly interested in:
- How good is the brightness compared to halogen?
- How is the colour?
- How well does the dimming work?
The dimming is especially where I'd like more info. I heard early versions of dimmable LEDs had a lot of flicker. I also experimented a bit with dimmable CFLs and found they didn't work very well at all.
Finally, ideally I would also want to be able to use them with an intelligent dimmer like Insteon, UPB, etc. Do these work okay together?
