I just got finished a 2D mag mod with following specs:
- 2D to 8AA battery holder
- Battery tube inner diameter sanded 1mm larger (holy crap what a job! :green: ) to accept those damned oversized Energizer 2500 mAh Nimhs.
- Shark converter
- 3 stage switch: 50 / 250 / 1000 mA
- Runtimes 35 / 8 / 1,5 hours correspondingly
- UCL lense
- 4*Seoul P4 U bin leds
- 4*McR20s reflectors
- Works best with Nimhs, but alkalines can be used as well. With alks the runtime at high drops to 30 minutes but other runtimes remain the same.
In case of emergency 2 D cells can be used as well. Low and medium level will work ok then, but you will not get full brightness at high.
Here is general pic of the mod:
That is what the business end looks like:
Yet closer look on the business end. It was very hard to get the emitters centered because the reflector hole is much bigger than the led dome.
Here you can see the current setting 3 stage switch. I left the original switch as it was for turning the light on/off. Watching carefully you can see a reflection of me and my camera...
At high mode the light head gets quite warm, some 50C at room temperature. You can touch it but you don't want to hold it in your hand for a long time. This makes me think that 15W of heat is pretty much the upper limit that the Mag head can safely handle.
Thanks for looking!
