[RE-wrenches] 110Vac LED resistance to weak grids in developing world

[Jesse Dahl]

I don't know about spikes or grid events, but my home is 3/4 LED and have zero complaints.  The warranty on them is a little weak compared to life cycle......  All of mine vary in K rating and lumens and work beautifully.
