This mod is actually a recipe of Old4570 (with an XP-G). I just replaced the XP-G and added the Fwd switch to handle the current

Considerable trimming wag needed, It is a tight fit.



Measurements....



Guys this time I was blasted!

Low: 0.16 Amp draw – 120 Lux

Med: 1.52 Amp draw – 1050 Lux (at turn on, latter stabilizes at 690)

High: 3.08 Amp draw – 1910 Lux (at turn on, latter stabilizes at 1310)

Guys this mod is pushing 550 lumens OTF at medium! Exactly what a similar mod with an MC-E was giving me at High!



Beam

Fat and Smooth. Really! At 1m hotspot is 1+ foot across and spill is 4 feet wide!



Issues

Well, there are and they are contributed to the Cutter board that is –as usually- very high for the Chinese flashlights.

That made the pill to screw less, hence rob some space from the battery. Screwing down the flashlight parts will push – through the tailcap spring- the WHOLE switch module back, breaking contact with the retaining ring, electrical contact too. To work it has to be tapped from the back to bounce the switch module in place in contact.

So....I will have to redo it, thinning down the LED mcpcb.....



Temperamental with a mind of its own, like the original Rantaplan!
