Highly recommend if you need flluorescent bulbs
Magnus—November 19, 2025✓ Verified purchase
Keep this company on deck if you live in California and have an older lighting system that uses fluorescent bulbs. You can no longer buy them in the state and the LED repplacements at Home Depot, Lowes, Ace, etc do not work. If you have a upgraded system that accepts those, consider yourself lucky and go buy them. After installing, there was 2 second delay before they turned on. I have not experienced the delay since then and the bulbs work fantastic. Read more

Good quality light and exactly what I needed.
M. Smith—February 12, 2025✓ Verified purchase
It was very well packaged but it took longer to get to me than initially said. Due to all the storms I understood it taking longer to get to me. I had checked locally and I was told it was out of stock everywhere in the southern states. Read more

kpd—November 10, 2025✓ Verified purchase
Hard to find at the big box stores, it's a very unusual bulb. The bulb was a perfect fit. These bubs last for years! I am very happy that now I don't have to buy a whole new fixture. Read more
