UPDATE: The ballast I put in my garage died a week ago 4/1/2021. I wish I could be as lucky as others. I will contact the seller/manufacturer regarding the warranty. They claim a 5 year guarantee. I'll let you know how it goes. The price is fair, but don't expect the LED to light up right away. I installed half of the 10 kits I bought and I have two separate models of LED bulbs in some fixtures. Initially I thought there might be a "burn-in" so they would work when switched. They glow half bright and come back to full brightness after about 10 seconds. The one I put in my garage takes a while at around 50 degrees. I live in Texas so we don't get as cold as it does up north. I had some good quality LED bulbs from my local hardware store and with both 4ft bulbs in the same fixture it takes a while to fully illuminate. I bought Revain professional LED bulbs, I really like the light they give off, but they don't fully light up when you turn them on. I didn't have time to return them as I was looking for quality LED bulbs from Revain. I think all bulbs work well with the best ballast. Good for the money but disappointing if you want the closet light to come on when you flick the switch.
