DIY WF-501B Host Assembly, Unmarked

This is the long-popular WF-501B host assembly. Made of anodized aluminum, it includes the bezel, heat sink holder, battery holder and tail cap with "clicky" switch and wrist strap. Note that the is the host "shell" only, it does not come with a heat sink, driver pill or brass ring. We plan on offering heat sinks for the host in the future but until then, you can search on Laser Pointer Forums and there are currently at least two sources for them. Packaged in a protective bubble bag and a white paper box. Available in red & gold anodized colors (select color from the drop down menu). Some hosts include a lens and a forward battery contact that can be pushed out. These ship with no branding applied.

Designed for use with two rechargeable RCR123A or disposable CR123A batteries, or one 18650 battery depending on the diode and driver used.
