:mecry: :mecry: :mecry: :mecry: ...IF I HAD TO choose...
After a little over-analyzing, here's what I think:
- M3
- M6
- M4
- M2
Start from the bottom - I do not have an M2. My brightest 2-cell bulb is an EO-9. I think the LED lamps are better options in the 2-cells arena, for my uses anyway.
Middle-guy M4. Not the brightest nor the smallest. Good compromise between size and power, but just not as versatile as the M3.
Power hitter M6. No comparison when it comes to power. Truly an engineering marvel. This is my hobby light. Its output simply amazes me.
Versatility winner M3. Not as powerful as the M6, but it probably delivers more light per mass. With a Lumens Factory HO-M3* or HO-M3T lamp, it can run either two lithium ion rechargeable or three primary cells. The M3 (non-turbo) version is definitely my favorite. It's handily-sized, lightweight, and nimble. Carrying six extra primary cells, I can probably work an M3 to last a few times longer than the M6.
*still no luck with the EO-M3 running two li-ion.
I'm surprised no one brought up "how can you make us choose among those?" The really sticking point is that they do not share the same power-house. In other words, how do we logically compare 2-, 3-, 4-, and 6-cells lights? Not exactly the most logical decision but it's good exercise for the brain.
