I agree as well but my one supplier says they sell a lot of them so I am looking for reasons to support that. My other supplier only sells LED lamps that are direct wired.I strongly believe that the bypass, direct-wire type is the only way to go. Why pay to keep the ballasts warm? It's similar to people who replace automotive turn-signal bulbs with LEDs, and then add load resistors to load the existing thermal flasher, instead of installing an LED-compatible one. Why waste the energy you're trying to save?
I recently had a few customer-supplied LED tubes burn out, along with a ballast or two, when mixed types were tried in various combinations. There was no warning on the tubes about mixing, and the customer did the un-boxing before we were called. We ended up installing new ballasts and fluorescent tubes, at his request, and cost.
Pretty easy to find LED self ballasted replacement tubes that work with shunted or non shunted tombstones.I do bypass lamps to actually get the benefits of LED lighting, not just the appearance of it.
Don't forget that you probably need to change the tombstones to a non-shunted type if the tubes have hot-and-neutral pins on the same side.
