This light includes square-cut threads, glossy finish anodizing, and an integral LED shelf. The included retaining ring will now work with the 17mm qlite driver, making for easy installation. The OP reflector produces a nice smooth beam profile. Just add a 20mm MCPCB with LED, 17mm driver, a bit of solder, and you'll be in business!
Custom Build Service ***CURRENTLY UNAVAILABLE***
For an added cost, I will build and test this light for you. Just check the box and also add your choice of 17mm driver and 20mm LED to your shopping cart. If you add more than one LED or driver please specify in the comments section of your order which you would like me to use in the light. This service may add 4-5 weeks of handling time.
