You will not notice anything different in the beam when the 2mm2 Flat White is used in a reflector light.
the sofirn c8t driver can be bought from sofirn store on ali. its max 4.5 amp according to them.
Is there a reason this wouldnt work?
its pwm tho so regulated should be better right?
this is still a DD driver so no regulation at all, just their main Mosfet sucks so bad it has limit the current a bit, but not with ultra low Vf LEDs
Ow oke thanks for the response. I already ordered some 7135s so i guess my soldering skills will be called upon 
MF04 on Osram 2mm² vs stock
NICE!
Which is which please?
Osram has cooler tint and tighter/sharper beam, not as fuzzy.
Thank you Enderman.
Edit.
What about data-throw?
Osram on left, stock on right.
In real stock is more warm than on the picture and Osram is less blue.
T:2s ISO 200 F: 4
I didn’t measured throw.
Yesterday was foggy.
From 5m osram has a hole inside the beam.
I guess the correct distance to measure is around 25 m.
You are right! :+1:
I measured osram led lights and GT xhp35HI version at 15, 20, 25m
If you have a hole in the beam at 5, 10m in MF04 with osram you are close to good focus. From the image I think it is perfectly dialed in.
Should any thrower have a hole in the beam at short distance ?
I still didn’t succeed dialing my Emisar D1 with Black Flat correctly … only 60kCd
Actually yes, the beam needs some distance to fully form. But depending on the light this can be only a couple of centimeters.
Yes.
The distance in which the hole dissappears depends on the relation of the diameter of the reflector to the size of the LED. The bigger it is, the longer the distance.
I documented my experiences regarding this topic here and did some simulations here and here (in German).
All focused lights should have a hole in their beam at close range. Even small edc type lights will have a donut-hole hotspot in the first couple of inches of their beam. Super throwers will have this hole for many meters.
I wish someone would make a new thread solely about focusing thrower LEDs with steps, tips and best practices. It’s one of those things people talk about but never in detail. When I made a thread about how crappy my spring bypasses were everyone chimed in and I think it was very helpful basic topic (to me) to rehash after so long.
This is around 30cm from the wall with convoy c8 and 7mm gasket from int outdoor.
This is around 1 meter from wall with c8. I didnt sand anything down just aiming at the ceiling unscrew the reflector a bit and tightening it again till best centering is found. At 3.05 amp this led is already insane in a c8.
This applies to all LEDs, not just throwers.
Thanks, exactly what I was hoping for. I replied with a few questions. On paper this seems like a much more practical solution than eyeballing or messing with a lux meter at too close range.
D1 reflector is not good enough for black or white flat. It is only good for larger leds like XP-L HI. Me also only got around 60kcd with white flat. You can’t focus it better.
