I bought mine on Ebay. I highly recommend purchasing the milky cover T8 tubes. I made the mistake of getting some with the striped cover and this produces uneven lighting.

The 4000K color lights are much warmer and look better for indoor lighting. The 6500K lights give the blueish hospital/industrial look.

Check out this store on Ebay.

The 4 foot G13 T8 20W tubes are what you are probably looking for. They take 120V AC directly (end-to-end) and fit in standard 4 foot fixtures.

I installed the 20W, 6500k tubes from LED King in my workshop in March 2015. One of the best projects / investments I've done in a long time. As my posts indicated at the time, I had an adjustment period for the 6500k lighting but after testing some 4000k ones, the 6500 was clearly the best way for me to go in the shop. Now approaching the second full year, the whole project has long since paid for itself. One tube failed a few months back for no apparent reason but was quickly replaced with a spare.

Regardless of which way you go, the milky white covers are the only way to go as the direct lighting from the other covers creates shadows from any object. Remember, direct LED lighting is not diffused and each individual LED is a point of light that creates small shadows as it passes an object. The milky covers acts to diffuse the light a bit though each fixture can cause some shadowing that doesn't exist with normal fluorescent lighting.

I bought a few of these for the garage and workshop. No issues so far and nice bright white color temperature. I didn't take the time to convert the flourescent tube fixtures.

I see a lot of unfavorable ratings on the Sam's Club lights. Considering that all of these fluorescent replacement lights have a built in power supply to convert the power source to a voltage the LEDs can handle, I doubt any will make the 50,000 hour, so called lifespan. Yes the LEDs themselves might survive that long but not the rest of the assembly. No matter to me though as the ROI is short when replacing fluorescents just from the energy savings alone. And you get a superior light source in the process.

When still running fluorescents, I was having way too many problems (failures) with the instant on, cold tolerant electronic ballasts and all that went away with the LED tubes. Happy so far.

I have eight each of the 8 foot long florescent tubes in my shop. They are the single end pin and instant start and the biggest problem I have is when it's warm and humid in Florida they will not always start, I suppose it's due to the high-voltage leakage when humidity is high.
I would like to replace them with LED units like the ones I have replaced in the house with a 4 foot long units.
Eventually I will replace them with LED units but it's winter right now and they start fine since the humidity is very low. Yes they have a slow warm-up time it's really cold but at least they start during the winter.

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

I have not found any cost effective 8 foot LED tubes. They all seem way overpriced. I talked to one electrician that does a lot of LED replacement projects and he said in most cases where they are replacing the 8' tubes, they just replace all the fixtures with 4' ones.

Anyone found an 8' LED replacement yet?

There's a number of them available but none that I could find that are cost effective. Probably because the lighting companies have for the most part abandoned 8' tubes for new construction. 8' and any bent tubes are all expensive .... fluorescent or LED.

While strolling through some of the big box stores, I've been looking up at their lighting. Many of these stores have 8' fixtures but they have been modified to hold (2) 4' bulbs. When this is done, the bulbs sit at a bit of an angle in the fixture and a center socket assembly has been added otherwise the bulbs would not fit the fixture. So far, all have appeared to be fluorescent but it is clear that during one of the past bulb change cycles they made changes. Probably to get rid of the overly expensive and short lived 8' tubes. I would imagine these will be converted to LED in the next change cycle.

Regarding bulb changes in large stores, some years ago I had witness to one of these change cycles. While I had never considered lighting in large stores that use fluorescent tubes, I had never considered how they maintain their lighting. It seems that traveling companies show up with a large crew of workers, several truck loads of lifts and however many semi loads of bulbs necessary to do the work. This is a huge project and usually the store is shut down during the time it takes for completion. All the fixtures are cleaned and repaired if necessary and all the bulbs are changed at one time. Maybe boring to some but I thought it was interesting and just one of those things that happen behind the scenes in modern life. I can't imagine the cost though ....
