2xTrinity
Flashlight Enthusiast
This is my latest creation. 3 MC-Es directly driven off of two LiIon C-Cells. (2-series, 6-parallel die arrangement) This was mainly an excuse to test out the MC-E, and use up some spare parts I had lying around (a tri-star mag heatsink, a tri-reflector, and a 2C host).
I also used a power mosfet to bypass the stock magswitch and cut the resistance. At some point I should be able to update the circuit with a thermal circuit breaker to turn OFF the light using the mosfet if the body gets too hot.

This is next to my P7 Ultrafire C2.
I'm actually just running cheap unprotected cells from DX (these) -- as the light is direct drive, the output dims to nothing sharply as the Voltage of the cells drops to ~3, time to be recharged. I'm using my pricier AWs in my incan, as those require low-voltage cutoffs for safe operation.


EDIT: the emitter tint is 6A, not 7A
The P7 Ultrafire C2 isn't really for output comparison, more to show the beam angle and color. It's also direct drive off a 18650 and it's only drawing ~1.8A as its Vf is high.
Also shown is an ROP with MOP, also drawing comparable power -- around 4.2 amps off the battery.

This is the ROP with Fivemega MOP cammed reflector defocused to just short of "donut hole" territory shown on the ceiling. This is how I use the ROP most of the time, as a flood rather than as a thrower. It appears my ROP has finally been de-throned as my portable flood light.
Color temp and CRI appears almost identical to my 3500k CFLs at home (eg toggling between ceiling bounce and room lighting doesn't change the color of anything in an obvious way)
Since this project worked fairly nicely, at some point in the future (when I get some more "funds") I want to build a similar MC-E array into a mag with variable output and thermal negative feedback (eg temp goes up, output goes down). That will probably have to be a D-host in order to fit all the circuitry. The ability to crank out nearly 2K lumens, or dial that down to like 10 lumens with insane runtime is something very attractive for a light to take camping, for example -- eg if we need to find a lost item in the dark, I can turn on the sun, or I can simply enjoy a super efficient moderate-output flashlight.
