Any cost associated with maximizing thermal performance at the mcpcb is well worth it. Iād gladly pay an extra 2 or 3 dollars per light to keep these Nichias cool. 3oz copper pour over the whole board and the thinnest dielectric should be sought out.
What thefreeman and JaredM said, this emitter will be WOW as iām now in my builds. You wonāt regret it paying extra bucks for every quality component!
Olga is a nice optic, and LEDIL is a generally a good choice IMO. The Olga RS will probably be the best for SFT and maybe XHP35 HI where absolute max cd is the goal, but for the SST40 and B35, check out the Gaggione LLC25N. Itās a similar sized optic without any injection sprue so the bezel / oring design and machining will be simplified. This line of optics is color mixing and doesnāt project a ghost image of the emitter in the corona. Cd/lm is on par with the Olga RS for larger emitters , both offering about 14cd/lm for the B35.
If any 1mmĀ² or 2mmĀ² Osrams or Cree emitters are also offered, Iām not sure who offers the best cd/lm and clean beam in the ~30mm optic range. The Gaggione LLC05N is rated at ~145cd/lm for the 1mmĀ² flats which is impressive IMO.
Yeah I have a few Gagionne lenses on my wishlist, still havenāt ordered yet because the shipping is expensive despite same country shipping , Iāll add this one.
I donāt see any ghost image of the LED with the Olga though. Iāll take a pic once I have installed it in a light.
I would really love to see it be no wider than the KR1, and possibly narrower. Iāve been wanting a Noctigon FW1A for a long time. Something I can comfortably carry all the time.
