I’m only about a year into the first of them, still have a lot of CFLs to switch over, not to mention recessed lighting incandescents. But for the 15 or so I do have, so far so good.
Lowes and Home Depot regularly run sales on them. I picked up four 60 watt-equivilant spots last week at Lowes marked down from $24 to $14 per. Incandescents normally lasted two years, these say 20+ (riiiiiight .... ) but I’ll be happy to get 6-8 out of them and then anything else will be gravy.
The only issue I see with them is that they don’t dim as low as incandescents would. But thats really it.
I am wondering how their internals handle the occasional brownout/blackouts when a storm comes through and the power may flicker on and off a couple times.
