No no, don’t worry, this is another led with a much better phosfor distribution. But even a slightly uneven distribution with the phosfor just a bit thicker (=more yellow) towards the center (my led) already produces the effect in a smooth reflector (have not tried OP yet).
Ahhh, I see…
Yes, smooth reflectors aren’t the 144Ax mates. I tried them in my predator’s reflector, many narrow TIRs, big reflectors, etc…always a slightly yellow center spot. Fixed easily with even very mild 5 degree diffuser. All medium, wide, and diffused optics worked great. I’m sure OP reflector will do OK since this the artifacts in 144Ax are much less problematic than XHP50
Ok, I just put the 144A in an insulation gasket and tested it with 50 mA from my power supply (sorry for not taking pictures, but I needed all of my hands):
- With aConvoy C8 OP reflector there is a very visible yellow spot in the center of the hotspot.
- With this 52.7 x 57 mm SMO reflector the hotspot is much more intense and there is only a little bit of yellow seen on a white wall.
I guess that the deep reflector directs more light into the hotspot and thus mixes the colors better. When you optimize the focal distance it might become completely invisible, only I do not have the equipment to try that.
My 144A shall go into a McR-27S reflector that I am currently waiting for. When it arrives, I will appentd my findings.
I see the m43 being the perfect host for these 9080 LED’s. That way you have enough of them to get some good output and it would make a truly amazing photo light.
I took a few pictures today with my triple 9080 and the color is fantastic. It really does make every other LED I own look bad.
Got my McR-27S today. The hotspot also has a light yellow center, but not as pronounced as with the C8 OP reflector. Maybe the XM-L gasket that I use does not adjust the 144A in the optimum focal distance. I still have to check that.
- No stock for all Ra9050 and Ra9080 219B/C series. The lead time could be anytime between 1,5 - 2 MONTHS!
Nichia headquarter decided to (temporarily?) stops the sw45k production. Don’t know why. 4500K has been a rare CCT in Nichia these days. My earlier sm453 9050 144A purchase delayed by almost a full month. Then I only got sw45k 9080 219B in limited quantity.
I’m still trying to get whatever stock left there.
