Review on ⚡ Emergency Adjustable Backup Battery with Hardwired Connection by Jeff Davidson

1 of 10 lamps does not work, ie when switched off only one of the two LED lamps lights up. After much negotiation, the company agreed to send me a replacement lamp, but it never arrived. After being interrogated a few weeks ago, I still haven't received an answer. Revain didn't help either as they can only handle full returns, not partial returns of 1 out of 10 bulbs. So the 2 star rating is only because 1 out of 10 lights are not working, but I need 10 lights for my final inspection.
