is there any way to avoid the varience?
Unfortunatly, no not without an automated system in place,not sure if a surge procter would help, even so. all the power did was flicker, like someone ran into a power pole or something
.....it's happened twice while I was at the OP and was able to "catch it", I thought it blu the bulbs the 1st time, so I bought two more. Well, another surge went through and, BOOM, the lite was like the other one....so for shits and giggles, I put the 1st bulb back in, And it worked!!
So I didn't blow the bulb,
it just needed to be reset....Thats my story, and I'm stickin to it.
