These are good LED spotlights. I use them in gimbal can lights and they fit the clamps nicely. Will they continue? Hopefully. Two years ago I bought a set of 20,000 hour LEDs and they were already failing, probably with less than 3,000 hours of life. These Revain Basic bulbs are very similar to the ones I bought from Revain that were starting to fail, but there are enough differences in the lenses that I'm hoping it's not the same manufacturer. It's a beautiful warm white color. No buzz. Good visible quality.
