Nice find! I passed on the first Defiant XM-L but this one has piqued my interest.
45 kCd and only 500 lumens from an underdriven XM-L throws a red flag, though. That’s likely to be physically impossible to have those kind of numbers with only a 5.6 cm (guessing) diameter reflector. Regardless it looks like a great host!
Just read and looked again, it appears the bezel inside edge is 2.5”. Cool.
This thing is huge. Good sized reflector, I believe 57mm wide, I think at least 65mm deep. Comes apart in 3 pieces, aluminum threaded pill, plastic isolation disk, definitely XM-L. Has a nice hot spot, one brightness level. That's all I can do from here, I'm sure Garry will post some pics later.
You can handle it Garry! It is very easy to disassemble. I know you will beat me to it as I'm Central time and can't look at it tonight until at least 7pm CST.
