These light bulbs are not bright. It’s more light a very dull blue cool light. These aren't white 3000k. These are absolute junk.

As bright as a 100w bulb. Plug and play no hassle. Brightness is around the same as regular light bulb as it intended to.

It's made of plastic and soft zinc alloy. The bulb has a very accurate color. The light isn't as harsh as the cfl bulbs.

The prong height on these is about 1mm shorter than the other bulbs that work. The divot in the center of the prong is significantly smaller on these. Would not trust the dimensions if placing in an enclosed fixture.

These have nowhere near the life advertised. Also had a lot of black dots/burnouts after limited use. These are a hazard.
