Newly Enlightened
Hello everyone!:wave:
A while ago, I had the chance to mod a quite unknown MTE H8-1. The light uses an interesting lens system to produce a circular beam.
Following my little build-log:
Almost all threads were "secured" with glue. The first glued part was the battery tube...
... followed by the lower part of the head.
Of course, the heatsink-pill was glued, too...
... like the secure ring in the front.
Fully disassembled. There were four lenses in this light. One small condenser lens in front of the LED, followed by a aspherical lens 2cm above, and two spherical lenses behind each other in the front.
The ground of the original heatsink-pill was really thin.
So I added some more mass to it. The aluminium part was press-fit and also glued with Arctic Silver thermal adhesive.
Used a XM-L U2 on copper PCB (without dielectric) from LED-Tech, which was also glued under pressure using Arctic Silver.
The new driver with custom modes got a massive brass contact and was potted with a high mineral (75-80% purest SiC) thermal adhesive.
Close-up of the condenser Lens. I enlarged the openings a little bit on all three parts.
Done! What a massy thing...:naughty:
For size comparison, next to a 4Sevens X10.
Ready for beamshots!
Target is at 65 meters.
60 meters.
95 meters (tree in the center).
25 meters.
195 meters to the small house.
The original circuit had 5 modes (3+2) and around 2.6 Amps in the high mode. The new one is equipped with two modes (800mA & 5.2 Amps) and starts always on "low".
Regards,
Vinz
