While it's not technically an ROP, here's a nice setup I put together for my S/O:
- 2D Mag
- Cheap KD 3aa to 1d battery adapters x2
- 6 Duraloops
- Mag xenon 5cell bulb
- Stock reflector and lens
She absolutely loves the thing and uses it all the time (mainly dog walks and garbage runs). No problems whatsoever to date, I've had to charge up the batteries about 5-6 times so far. The stock smooth plastic reflector does not produce the prettiest beam, but believe me she's not wall hunting; and in real life usage who cares?
I do not run any of my ROP's (lo or hi) with plastic lenses or reflectors, it may be fine but I need that peace of mind. Along with the fact that I am not limiting myself to short runs, constantly worrying about melting something. ALSO, do not run any ROP setup with the cheap KD battery adapters, they have way too much resistance and would probably melt down.
So if you want to start off with a cheap setup to get a feel for what modding a mag can do I highly recommend the 5cell magnum bulb on 6 cells. The adapters are around like 2 bucks each and some good eneloops/duraloops won't run you too much along with a decent charger if you don't already have one.
