I was asked to help a friend move more heat from his 5 watt "D" cell mod with a "push in" battery tube heatsink and came up with this heatsink.
It threads into the mag's head just like the battery tube and by threading in or out will accomodate the SO 27 and SO 20 reflectors and the 30mm optic Elektrolumens sells and with a thicker lens o-ring (included) will allow using the SO17 reflector and NX05 and Fraen low profile (narrow beam) optics. (And maybe others that I don't own) Screwing the battery tube against the bottom of the sink locks it in the desired position and if you sand the annodize off the end of the battery tube, you will create a strong path to ground through the sink. The sink disk is about 3/8" thick 6061 aluminum and 1.535 in diameter threaded 20 tpi as is the battery tube. It uses my PR base connection for ease in changing hosts
I include some thermocote heatsink grease for the threads and the thicker o-ring mentioned for using the smaller optics and reflectors. The LED shown in the picture is not included.
The price is $16.00 shipped in the US. Cash Paypal only, please! Please PM me for international rates. I have 5 on hand and will make more if you want them!
