The HaikeLite MT07S - HI seems like a good candidate for this emitter for any that don't want to electrically insulate under the emitter base. Looks like you would just need to use plastic screws to keep the driver from grounding to the host. Maybe a piece of kapton tape under the 2 driver screw a points for extra measure.
Pluses:
Smooth reflector.
The light would already have a large XP emitter base.
I'm assuming a buck driver? Just sense resister to 4 or so amps. Should have good run times
Black flats arriver few days ago. I putted in an L2 and a GT mini. Not tried them just picked the first. In the GT mini I got strange ring beam and only 160 kcd.
Replaced the reflector with the Emisar D1S (perfect fit) and I got 214 kcd. Still not happy with results completely. These numbers are measured with GA cells. With HG2 it was worse. The L2 is worse then old XP-G2 S4 2B dedomed.
You need to check the focus outside on an object that is far away. It’s a lot of work to get if perfect. The smaller the led and the larger the reflector, the more difficult it is.
I just put a Black Flat in my D1S as well… amazing !
I can’t measure the intensity accurately but according to the ceiling bounce app “calibrated” with my stock M3XS, well I hit a mere 350 kCd…
Even if I’m 20% wrong it’s still really impressive and the beam is really tight !
Oh, and BTW I also put one in the said M3XS… 450+ kCd :heart_eyes:
The luxmeter app available for Android is called “ceilingbounce” but you can also evaluate throw by stating the distance between the sensor and your flashlight. It does the calculation on its own and gives you kCd approximation.
You could use the D4 Nichia 219C firmware, it limits the maximum output at 80% PWM. If you need to go even lower than this, you need to alter the ramping table further down. It’s a nice and clean reversible software solution.
I just finished my GT mini with D1S reflector yesterday and I can’t go above 255,5 kcd with the OSRAM KW CSLNM1.TG. I tuned the focus for hours. Measuring every tiny bit of change. With Black flat it was 213 kcd. I just can’t understand how can it be 340 kcd. And 300 with C8? How?
