Got mine with 3000K SST-20, and get a bit over 600 lumen on “turbo”. It was an impulse buy and although the build quality and led choice is very nice, I’m not really sure if it adds a lot to what I already have (but then, what other flashlight does do that?).
At least the SST-20 is doing its thing, produces a very attractive beam and at low mode in the hotspot I measure 97.8 CRI, R9=88, 2960K and duv –0.0008. At higher modes the CRI is slightly lower but with rosier tint.
I’m still trying to figure what the merit is of extreme CRI in a throwy flashlight
Also, is the driver side end of your battery tube anodized? That seems strange to me. I almost want to sand it down and let it contact directly with retaining ring.
Should be fun. In a Lucky Sun D80 that has the same reflector diameter I got 140kcd with the White Flat, I reckon that this reflector is slightly better, but I have no idea if the current will be correct.
The CCT doesn’t make a difference in output. It’s the flux bin that matters. Warmer CCT are usually limited to lower flux bins. I measured many NW versions of the same flashlight brighter than CW version. For example I measured output of several E07 and to my surprise the NW one measured brighter than CW.
I understand, but after looking at the datasheet the flux bins are very linear with the tint. The highest flux bin 3000K is not even as bright as the lowest bin 4000K. I realize this doesn’t apply to all LEDs.
1,250 is only going to be achievable with the low CRI 5000K or 6500K. The 3000K is going to max out at 800 “LED Lumens” and even less since this light isn’t driving it at the absolute max.
I think the hype train made a stop at your house and your ticket was punched.
Thanks,well NEALE needs to make that clear on his website. I was not familiar w/ that led. This is what he lists! He needs to break it down by color temp. or say this is for 5000K 6000K ect.
Yes, my Nightwatch Seeker runs at 5.13 A at turbo, in my test of the 3000K SST-20 that is nicely close to max btw, and I measured 830 djozz-lumen, that should be 770 real lumen when compensated to maukka’s calibration. For a reflector light I usually take 82% off that for OTF estimation, which is 633 lumen. I just remeasured at 30 seconds: 643 (real) lumen, pretty close to expectation.
A low CRI cool SST-20 should be almost double that.
ok,thanks,by the way NEALE advertized it I would have no way of knowing that. He did not specify what color temp. that was and I really knew nothing about this LED!!!
I never thought about how in other LED’S CW is usually more lumens than NW,But not always. One example is my TN42vn90 with the CFT-90, My 5500K is the same output as the 6500K which is:
So if mine is ~ 650 lumens[not 1250] than it will probably about 50Kcd instead of 90Kcd!
I hope I am wrong.
Although that is not always the case,Oslon LED’S[~700L] and my OSTS TN31mb is ~750L/477Kcd w/ xpg2,albeit a much bigger reflector, same LED in my TX25C2vn DD/Single mode is 850 Lumens/75Kcd
