Review on 4 Pack Hykolity 30W 2FT LED Shop Light - 3500Lm 6500K Super Bright White, Linkable Ceiling Fixture W/ Built-In ON/Off Switch & ETL Certification. by Maurice Cunha

I purchased 10 of these 2 years ago. The description says 5 yr warranty. One has completely stopped working and two have about half of the leds not working. I contacted the company over a month ago and have heard nothing from them.UPDATE. Now 3 have completely stopped working. I contacted the seller and I contacted Revain. I've heard nothing from anyone. 5 yr warranty apparently means nothing. Revain says contact seller, seller does not reply.With no help from Revain I finally got hold of the company and they refunded what I had paid for the lights. They say none are available for replacement so I'm going with another brand of light. I'm sure all of us who have bought traditional style led bulbs or any other led are going to have problems with the 50,000 hr or long warranties. I now have an outside, wall mounted light with intergrated led bulb. It has stopped working and I must replace the fixture, can't just put in a new bulb.
