I replaced the CFLs in the office with Cree 100W equivalent LED bulbs a while back. This involved some shenanigans with the ceiling fan fixture that required installing a longer nipple so that the bulbs -- with their big heatsinks! -- would fit. I also installed one soft white and one daylight bulb to try to average things out.
I've noticed it's been getting dim in the office lately when the sun goes down. Yesterday, I finally took a good look at the problem and concluded that the soft white bulb was failing. In theory, it's under warranty, but in practice it will be annoyingly inconvenient and expensive to get that warranty honored. So since I was in Home Depot yesterday on a different mission, I checked out the LED bulb aisle.
I considered getting another of the Cree LED bulbs with the huge heatsink, but I noticed that Philips had a much smaller, supposedly 100W equivalent LED bulb for about 2/3 the price of the Cree. I figured I'd try it and have now installed it into the fixture.
There is a lot more light in here now.
I wonder what I should do with the failed bulb...
