Looking for Astrolux E02 driver replacement

Received Astrolux E02 with faulty driver and looking for replacement. Original driver is 20.5m with side switch, but electronics on it can fit only in 17mm tube hole :confused: Any idea what to look for?

my current TA series 20-22mm needs 17.5mm parts diameter

I could make a 17mm Layout with 20.5mm diameter if needed, but till I get the board a lot time will pass

So i guess, im gonna cut bigger hole for electronics, then i get bigger chance to find driver;)

Couldn’t you send it back ? Get a discount ? Have them send a replacement board ?
