I found what seemed like some nice LED blubs at Lowes..
Shop Utilitech 40-Watt Equivalent Indoor Warm White LED Light Bulb at Lowes.com
But, I've already had to return (for free replacement) four (4) of these
new Utilitech 40-Watt Equivalent LED blubs. (out of about a dozen).
Not very long lasting.. I do get a bit of high line voltage at times. Right now, it's 124.3 vac.
My TED recorded a peak of 140.5 vac at 9:30AM this morning..
If the line is really getting that high, when the LEDs are on, I can see
how that could cause damage to the PS in the base of the blubs..
I do have a couple of the Philips 12-Watt (60W) LEDs,
12-Watt (60W) LED A19 Soft White (2700K) Light Bulb (E)*-423343 at The Home Depot
and so far they seem to be lasting a while..
