Extend the life of your expensive "lifetime" LED luminaires.
When LED luminaires fail, it is almost never because of the LEDs themselves, but the "ballasts," or more accurately, custom power supplies, don't always last as long as they should. Anyone with a basic knowledge of electrical wiring and safety should be successful in replacing the factory power supplies with appropriately spec'ed replacements such as this one. I was able to replace the existing box using its original screws and holes, and the results were totally satisfactory.

Worked, saved me money
Thus far, so good, I replaced the attached LED driver with this new one. Saved my fancy LED light from going into the trash, and saved me like $70. Was not the clearest thing in the world, but for my experience, all the colors lined up, except black (my light wiring), that was blue on this new one. Hoping it lasts

No way of knowing
I can only assume the problem was not with the driver I have or the one I ordered was also defective. After installing it the light fixture would still not function so I returned the item at my expense ($17.84) and was only reimbursed a portion of the purchase price.
