When will you learn that Theory only works in a vacuum ? lol
OK, maybe I'm a glutton for punishment, or maybe it's Costco's Pied Piper thing, but my wife and I were in Costco today and they had the R30 LED bulbs. Actually, they are PAR30's, so they can be used in damp locations, out of the rain. They are rated 650 lumens, draw 13.5 watts and emit light at 3000K at only a 38 degree spread.
So at only 15 bucks each this time, (with a 15 dollar instant rebate), I bought 2 of them. I installed them already; they are dimmable, emit decent color light, but the spread angle is a little odd compared with CFLs, and incandescant R30 bulbs, or the previous LED lamps that failed and I returned, that spread out probably 90 degrees due to their reflector.
These LEDs have 6 individual led units in each bulb, and its like stare-ing into the sun. For 30 bucks total, with a 5 year warranty, hey, I'm game again. Hoo Hah!
How can you resist buying anything at Costco? If you enter, your lost, and your wallet is at least 200 bucks lighter; actually 350 bucks today, even with all the coupons and rebates. Buy in bulk and save; who invented that crap?
