These are cheaper in a large quantity than retro-fitting your older 4ft two light fluorescent shop lights with 120v led 4ft lamps. Easy to install and very bright. Better light than the ufo type led's.

Just finished installing and testing. If you're installing new lights this is the way to go. Simply hang up, and plug in. Easy to install.

Super bright. Fantastic light output. Much brighter. It's like being outside on a sunny day. The difference is night and day. It is fantastic.

Not even installed for 3 months. Out of the 14 that i use almost daily that are not working correctly.

These bulbs are very bright and have a warm glow even at full power. They all dim well and without any buzzing. Haven't installed dimmer, yet.

Only downside is they are made in china. They exceed their cri rating of 80 at a measured 84. They are 75w equivalent at 940 lumens, which for a br shape at this power consumption is adequate.
