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.
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?)
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.
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.
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 .
So glad to hear it ! and thanks again for helping me figure that out! My cyan with cyan switch and gray with amber swtich should be here tomorrow or Monday! Also, I didn’t even think about how nice it would look just having the white boot on them. Excited!
