loupe to LED

I converted the Princess Auto Power Fist loupe to a super bright red LED today. I deliberately used two 240 ohm resistors in parallel to raise the current into the LED to around 30mW. The primary reason for this was to generate more light atop my charts. I'll need to try it in the field to know for sure if this has been successful. A spin off, of course, is that it will let the four AA batteries last longer.


If the light isn't much better, than I can try putting more than one LED under the magnifying glass, aiming down. Won't be a issue then!
