    I have found that the LED's last forever but the power supplies fail quickly. So the 4' led replacement tubes only last a year or two then they no longer light up. best is to get separate power supplies and led's but they cost more.

    14k lumens for $28 sounds like a good deal. Can you share your source?

    I have not seen LED tube that have​ an external driver. Tubes that work with a ballast still have an internal driver. The ballast does not contribute anything to the equation.

    I always wonder when I buy something like that from the bay if the ratings are inflated. Is it really 14k lumens or is that like sears compressor horsepower? It is 14K lumens for 1/2 second before it overheats and melts. So it is throttled down to 4K actual output but the leds are capable of more. I know the lifetime claims are wildly inflated.
    I do not trust the China DB claims for ear protection but I trust Sweeden's numbers AKA Peltor. I can get 10-20 DB reduction by moving the microphone from the motor to my ear where it counts.

    I've got new LEDs in my new shop.

    They claim they will burn for 50,000 hours. If I monkey in there for 25 hours a week, I'll be needing to replace them in 38 years.

    I'll be 105 and I'll need some help.

    According to my lumens meter, they are basically spot on, some a little more.

    I did the same 8 months ago. So far, so good.

    Same here. I got 8' fixtures for $20 from 1000bulbs.com and 5000k, 2000 lumen LED bulbs from Amazon. The bulbs came in a 20 pack for about $120. I have 9 fixtures total and it cost me a little over $400 to outfit the shop. One of the best things I've ever done.

    As others have said, you'll be able to purchase ballasts, sockets and LED refit lamps for a long time, that will allow you to keep the fixture appearance constant........Rod.
    You could argue that by removing the ballast, the "fixture" becomes a junction box, and the new "fixture" is the LED tube. Ballasts run fluorescent tubes at several hundred volts, so the tombstones are good for 120V.

    New installation. There is ZERO reason to buy obsolete fluorescent fixtures and convert. Buy new fixtures and get at least some warranty. I have 2x2 and 2x4ft troffers in my basement that I purchased from Both HD and Lowes in the past three years.
    They run 2 to 8 hours a day, 5 to 6 days a week. No issue at all, no flicker, work at 50 degrees (basement is cold in winter) and put out more light that a 4 bulb std fl fixture.

    You could argue that Jason, however the inspector won't agree with you..........Rod.
