Bests & Worsts Reviews from Amazon

I purchased the pack in 5000k. At first I was very happy with how bright and great the daylight color was. However after only two weeks of operation, one of the lights began flickering horribly. I was going to rate this 5 stars but it appears there is a quality control issue. At first I thought something was wrong with my power output or my dimmer. However after recording the lights for a while I was finally able to catch it in action. One of the bulbs started flickering and I switched it to a different location in the light sockets. Sure enough the same bulb in a different location flickered, this time even worse than before. There's a QC issue here, likely there's chips inside that might be broken or poor quality. Additionally the heat might be a cause. If you buy these, I'd definitely give them some time to "burn in" first and let them heat up under regular load before deciding to keep them or not. *Update* I returned these and purchased a second set as replacement in July 31 2019. It is now November 2019 and another light bulb is flickering and struggles to turn on. When I flip the switch 3 out 4 bulbs turn on instantaneously but one is partially on, meaning only some of the LEDs inside turn on and the rest flicker. Until about 5-10 minutes after the bulb warms up the rest of the LEDs in the bulb turn on. Even then they flicker occasionally. I gave this company two chances unfortunately they blew it both times. They have some severe QC issues. I would go with a more reputable brand. *Update #2* It is January 2019 and two more lights started flickering. I purchased two boxes of these and bulbs from both boxes are flickering. So far 4 bulbs from two different boxes have gone bad. Clearly these were not built well. I called Great Eagle about these and was offered a refund quickly. I appreciate the quick refund but unfortunately it's not a brand I'd purchase again. **Update #2** it’s July 2020 and of the two boxes I purchased (6 each for a total of 12) only 4, one third remains working. They have all slowly started flickering and died out completely. Not recommended.
