2c m@g mod

ok i have a 2c M@G light, VY0T 5 watt, 1 x Arctic Alumina 14.0g, 1 x Arctic Alumina Adhesive (2 Part Epoxy), and 1x Hotlips-C. i want to run this on 3 cr123's can i run it direct drive or do i need somthing else for this mod. thanks

You need to add about a 2 ohm 2 watt resistor and actic alumina that to something aluminum in there too.
Take all precautions to avoid a short in that tight space.
Good luck.

were can i get a 2 ohm 2 watt resistor? and how much tolerance can it have?

I have used 1.6 - 2.2 Ohm with good success with comparable ***T Luxeon5s.
www.nteinc.com has those listed I think.
Or do a search for metal film 2 watt resistors with google.

thanks for your help 3rd shift i ordered 4 2 ohm 2 watt resistors can't wait to get this project going

guess what

What?

mrdee,

instead of ordering resistors online.
you can buy them from one of your local electronics stores and then won't have to wait for them or pay any shipping.

do you think radio shack would have them i look at there web site and they only had 1/4 and 1/2 watt

Radio Shack might. If you have access to a Fry's store, they sometimes have some good selection as well.

My Fry's electronics used to until I cleaned them out of these resistors. /ubbthreads/images/graemlins/grin.gif

Good luck on that project.
When you get the star, mark it's (-) "leg" with a black marker before pulling it from the star.
There are some threads with instructions for pulling emitters from stars safely.
Clip the leads back a little after pulling the emitter to protect them.
I use a sharp pair of scissor blades to clean off the crud from under a pulled emitter.

I put my resistor on the negative ground wire in, just in case it shorts. = Nothing bad happens.
Just keep the wire from resistor to led insulated all the way there as you would with the positive lead wire.

thanks for all your help
