In these pictures you can see the MGI opened up:

Here it is lined up with a couple of other fairly well-known lights, the SureFire L4 and Baby Pin:

You can see that the Baby Pin puts out slightly more light, although both are obviously brighter than the 5W SureFire.

Here are the same trio's beams on my speckled ceiling from 20 feet below:

At distance the MGI starts to match the Baby Pin's output, although they both maintain the same brightness advantage over the L4.

And finally, the MGI's lux reading:

So it approaches the original full-length LGI's output but in a smaller package. Given the handier and more pocketable size, without any delicate circuitry inside and much less to go wrong, the MGI turns out to be a pretty nice mod indeed.

Since it rivals the performance of today's complex $100-plus Flashoholic specialty mods, if I were to build them for sale they would probably go for like $48 shipped. With an 1/8th-inch thick copper heatsink and lockout clickie tailswitch included, what else do you need? [EDIT: Mr Bulk sez this light will not offered for sale. "With the Up-coming Baby Pin, there will be no need for any other flashlight!!!"]

It's time to get back to basics. We're building flashlights, not refrigerators.

As the Mexican Bandito would say, "Circus? We dawn nee' no steenkin' circus!"
