YaoKuem LED Emergency Exit Lighting Fixtures with 2 LED Bug Eye Heads and Back Up Batteries- US Standard Emergency Light, UL 924 and CEC Qualified, 120-277 Voltage (4-Pack)

For the price, these are worth it. They are easy to install for anyone who has basic electrical knowledge. They seem to be able to hold up to the required 90 minute test requirements, but until next year I won't be able to accurately claim that. If you are in need of cost effective emergency lights for your business, or for installation, you won't beat these. I will continue to order these as long as there are no issues in the future.

lightweight, led, bright, dunno yet as to lifespan but will see

worked well

Good product as specified

Thanks
