These look fantastic and give off a nice high CRI light. I've We tried a lot of brands and both of them were too dim, too bright, or various combinations of those. Finally, these tribright LED bulbs were perfect. We have it on a dimmer and it works perfectly with that. They've only been installed for about a month, no any quality problems for now. Nice upgrade from 150 Watt incandescent bulb in the garage Screws in like a regular bulb. Easy to adjust the panels to direct light. Brighter and less expensive. I may buy a couple more.
