I’d like to briefly share “the Chinese Enthusiast Customized R9080 5000K XHP50-Like Emitter” that was customized by a enthusiast in the Chinese flashlight community as a hobby, this emitter doesn’t actually have a name, so that’s its name. Or if that’s too long for a name, you can call them “that Custom XHP50-Like emitter”.
It actually has an unused name, FL5009R. I know the name because, it has a newer brother, FL5008R, which was re-customized by the customizer of FL5009R and another enthusiast, with the advantage of a smaller die gap, and the disadvantage of a slightly lower Ra(95) and R9(90). I currently don’t have the FL5008R, and FL5009R and FL5008R are currently sold out on the market (the initial sellers).
This emitter appeared around August last year and was only sold on the secondary market, here is a post on the forum about it. Ra97, R9 95, -0.0007 DUV, this was mainly to fill the gap in the market where there was no R9080 XHP50 and to achieve higher efficiency with SanAn’s latest chip, and btw the pads that can be switched 3V/6V. The manufacturer is probably one of the OEMs of the FFL emitter called 弘欣顺(HSXLED)/Hopthink. There were actually a few people who customized similar emitters before and after and I have to say that this is not the latest, I mainly do a brief share about it.
The emitter color is great, But because of the die gap, there would be a donut and I had to remove the centering ring to eliminate it.
The 2 Custom pictures at the bottom seem a bit too dark, probably a brightness issue, but it’s just a brief comparison anyway.
The main thing that caught my attention is the comparison between the 519A and the custom emitter, looking at the green leaf on the upper-right corner of each photo. It seems that the custom emitter does much better at rendering the dark green compared to 519A and 219B, much closer to daylight. Usually blue LEDs fail at this because of a gap in the cyan region in the spectrum.
Indeed, looking at the spectrum tests on the Baidu forum, the cyan gap is much less pronounced than 519A, and the R12 (deep blue) reaches 89, while most LEDs at this CCT, including 519A, tend to have R12 below 80.
Is there any way for us to get these emitters, or are there plans for larger-scale production?
Forgot to ask: in person, is the difference in dark green rendering (between 519A and new LED) as pronounced as it seems on camera?
Also: why are the red flowers “blown out” toward the right on the 519A photos? Were they just overexposed, or is there a color rendering problem? Sometimes I find blue-pumped LEDs to give a grey cast over everything due to the blue spike.
They look somewhat oversaturated to me. The gamut index Rg of these custom emitters seems to be really high, maybe over 100 or so (the FFL909A 9V I tested earlier was at 107 which is extremely high).
I think it’s likely just overexposure and brightness differences, or an issue with my phone.
It’s hard to redo a comparison because I swapped emitters on the same flashlight in succession.
Perhaps somehow this picture is misleading. After all, subtle Ra R9 DUV differences would have been difficult for the camera to capture, and would have been more affected by other factors.
