Thanks Hank! Sounds interesting...
Oh boy, looks like I’ll be ordering another kr4… and probably the d4s too… thanks Hank!
I hate to ask this question, but if you have the ability, is there anyway to give an estimate lumen rating for the kr4 or d4. I will look at the CREE data sheet and probably get a decent estimate… but I am just curious, more so compared to the 5d 4000k. I feel like my 5d 4000k lights are close to as bright as my 3a 5000k xpl-hi lights. Hoping the 8d is similar too!
Hmmm, the 8D's are T6 bin, so down 2 levels from the V2 5D's, so from what I've measured, they should be lower. How much to be noticeable is another issue.
Is not V2 5D 4000k and T6 8D 2800k?
Should be lower, right? I guess I do not understand bins well, so if someone could clarify, I would appreciate it.
I do understand one letter/number combination indicates distance from BBL (or maybe both?)
So much still for me to learn.
T6 and V2 are bins, for brightness or lumens output, not color, tint, BBL related, etc. Explained here: https://flashlightwiki.com/Brightness_Bins
The wiki has some good basic info, though dated, it's pretty much all or mostly relevant.
T6 is a brightness bin, 8D is the chromaticity bin, you need to check the XP-L datasheet , T6 means 280-300lm at 1050mA, 8D is below the BBL. For reference kaidomain has a 90CRI XPL HI T5 7C1, one bin lower and above the BBL, so I guess this a good deal.
XPL HI at 3000K is too warm for me.
I wonder if I can get a high-CRI XPL HI light by combining 2 or 3 of these high CRI XPL HI leds with maybe 1 low-CRI cool white XPL HI.
Thank you. Foundation of understanding is progressing. I am appreciative.
Hi Hank. Do you have a measurement of the lumens output and the throw of a KR4 and / or a D4V2 with these LEDs?
T8 8D should be 10% less brighter than the higher bin LED like XP-L HI V2/V3.
Noctigon KR4 Ti all colors available,
According to the Cree XP-L spec sheet, lowest luminosity for the 8D bin is 280 while for the V2 is 400, so looks more like 30%, in theory. I was wondering if you had measured one to make sure.
Awesome! I have another chance!
Hank any info on the new light DT8?
Looks like 2 choices now on Raw Ore titanium D4V2 as well as KR4 colors returning.
I missed out the 2850K XP-L HI 8B few months ago and now just ordered the 8D. Couldn’t find any beamshot and tint photos online hopefully it is good!
Truly impressed with the look of my new cyan d4v2 with cyan back light . Photos don’t do justice .
Me too. When’s that coming out? :heart_eyes:
You Firelight2 are playing with me ? Right ? Already a photo shown here . An cyan d4v2 with white boot is a beauty by itself and the total effect is very cool .
