My observations since I posted this last year. I would think the plastic lens would melt with an LED, as I ruined a couple of stock reflectors pretty quickly.
I got the MOP and smooth aluminum reflectors from Kai. Both work well. I definitely like the orange peel better. The mirror has a little more throw, but not that big of a difference.
So I put the Malkoff in a 4D. It's a great unit and is built very well, as is everything Malkoff. However, I've made up four 2C Mags with these 300Lumen rated Cree LEDs I picked up on auction sites for around $16, along with the Kai aluminum reflectors and glass lenses. They have decent tint and are only a tiny bit less bright than the much more expensive Malkoff ... although definitely not as bomb proof as the Malkoff. Makes for a nice light to carry in the vehicles for around $50 total. I love the 2C Mag for many reasons.
Here's one I did up with a vintage 2C with flat tail cap & old style bezel, and another newer one I did with a paracord wrapped tube. Also did up a Chevy Truck 2C for my Canyon.
The only think about those Kai reflectors is they're just a hair too big, preventing the bezel from being fully screwed on. I wish they'd machine them down a little more.
