The ballasts (in the case of the 277 VAC/60 Hz stray voltage) have been cut out of the path. The LED tubes are powered directly by 277 via the non-shunted tombstones original to the fixture (rated at 600V).

Even on a test bench with no fixture, the LED tubes exhibit the issue. Depending on which pins are powered (according to the manufacturers instructions) there is voltage present on the heat sink.

The Eurilight LED tubes are of Chinese manufacture, designed by Irtronix in California.

I would contact the manufacturer, maybe they need a recall.

They responded to my emails twice, but I have yet to hear back from them a third time.

It's a waiting game...I hope they hurry.

In my view these are unsafe tubes, and they are available at homedepot.com...

Maybe notify HD, that they pose a shock hazard. They for sure sound like a bad design. Maybe they'll remove/discontinue them in the meantime. I'm assuming they're UL listed? Maybe contact UL labs? You might just save a life.

Ok, I didn't understand or missed the part that the heat sink was unbounded to the chassis . In that case holy cow. I would contact Home Depot , that will get the manufacture'r to start paying attention.

I haven't been able to get a video together. This has become more of a nuisance than anything i.e., not a part of my regular job...disassembling and testing of a stupid light bulb, if you get my drift.

A can't represent my employer officially, so I am left to waiting for the safety department to make a determination. They can sound the alarm officially.

I did call the Consumer Product Safety Commission, however, and start a case. I don't know how long that takes.

If anybody here comes across a similar device, I would advise caution and testing. If more people come up with the same results it would only bolster the concern for safety.

I am heading to HD later today and will see if they have any of those lamps, I may get one and do some tests and pics if I can.

Meantime, since this appears to be a safety issue, I am copying this thread to the Safety notices forum.

I have been using either Keystone or Eiko with the ballast removed and so far good luck. That can't be right, should be nothing there. Has to be defective. Time to find another brand. I don't think you're going to escape the made in China, but maybe somebody more well known.

I have the same style tubes from two other brands, might have to test them.
