Couple Questions about a M@g Mod Build

[buschpounder]

I have a 5 D M@g sitting here with an extra Cree Q5 and a UCL lens doing nothing. I was thinking of getting a fatman driver, MCR45 reflector and Hotlips sink and putting them all together. I can't seem to find a source for the MCR45 reflector or hotlips. Are they still being produced? If not, are there equivelant reflector/one LED heatsinks out there? Thanks in advance for any help.

From the TaskLed website concerning the Fatman driver:

"Note, Fatman is a Boost regulator (step up), so input voltage must be less than the output voltage to ensure Fatman remains in regulation. If the input voltage exceeds the output voltage (at the dialed in drive current), Fatman will no longer regulate and the input voltage will go through the series inductor and schottky diode directly to the load. This will cause the output current to a LED to rise rapidly since LEDs have a very steep Current vs Voltage curve (Vf). "


You need a different driver. The Fatman is a boost driver. You need a buck driver with 5 D's.

I have an SOB buck driver coming from the Sandwich Shoppe for a similar mod as yours.

If it's a MOP reflector that you want, they can be had from Fivemega.
