21700 tube light

Lol, like many people on this forum there’s always something rattling around in my noggin. Don’t know which one will make it to fruition.

007 I considered a press fit retaining ring but thought it has limited benefits over the current set up. As it is the driver is a firm fit so ground contact is good. If I make a retaining ring I’ll definitely go for threaded.

The reason I mentioned it, is I have Had a few drivers that didn’t make good contact to ground. The light would flicker, not light up unless bumped or change modes on its own. The driver your using looks to have a way better ground ring than any I have used. It may work fine, but if you use something like a amc7135 105c driver it may give you problems. At least it’s a simple fix. :wink:
