Is it a good idea for a flashlight including three 3000k lights and nine 6500k lights? The total is 12 LEDs.
Will you guys be interested in such a flashlight?
Looking forward to your genius opinions.
It all depends on the flashlight, I really can’t stand anything in 6500K and avoid it when possible.
Yes. The result will likely be a tint below BBL. I’ve done something similar with 5mm LEDs (9x2300K, 3x5600K). Quite warm and super-rosy, so I guess your arrangement will be even more lovely.
Just have nine ww LEDs and three cw LEDs 
.
Edit: Ah, what do I know - show us prototype beamshots!
Edit2: Want one for testing 
Makes sense. what if there’s option for turn all the lights on or only turn on a few of them. In that case you will have option to turn on the 6500k or not to, it’s totally up to your needs.
For examples:
Mode 1: Warm white with 2000 Lumens.
Mode 2: Cold White and Warm white with 8000 Lumens.
Mode 3: Cold White with 6000 Lumens.
Mode 4: Cold White with 3000 Lumens.
Mode 5: Cold White with 1200 Lumens.
Mode 6: Cold White with 300 Lumens.
Will you be interested in such a flashlight which with 6 modes?
Mixing temperatures to get a better tint - yes, but my preference would be a final CCT of 4000K or lower.
Switching or ramping between temperatures (like the BLF LT1) - yes, but I would prefer the highest CCT to be no more than 5000K.
However, after thinking about it a bit more I probably wouldn’t buy either type of light with 12 emitters - it would most likely be too large for me to use regularly.
Maybe
Hum…9x6500k and 3x3000K?
Isn’t it going to be much more on the Cold White range than in the Neutral even with those 3 x 3000K?
It is not like what Unheard posted above (9x3000K and 3x6500K), it is the opposite…
I admit, my light sends you in the deepest red sundown. Not a light one would take outside.
(no ambient light)
5000K is my maximum.
5700K or 6500K only if it’s E21 emitter, otherwise no.
Yes I would like to have 3000k in my bedroom. It gives me a warm and relaxed feeling. I saw it at one of my friends home.
If they can switch between CW, WW, CW+WW modes then it could be interesting.
If you only have one mode (CW+WW) then it’s probably moot. Your final output will end up around ~5000k (admittedly with rather rosy tint).
I would have to see the flashlight first. I have around 60 torches and I have viewed everyone except 2 before I have purchased them. It’s just my way and I am this way with everything I buy. The only two lights I bought because I thought they where cool before viewing were the DN35 and DN70. One I gave away and the other one sites in a junk box. For example, the new Manker MC13 deal, I did not purchased the deal because there was no way to view it but now there are a couple of videos out. After viewing them I am glade I did not buy it because its not impressive to me at all. I purchased the EC03 instead and its a nice torch and I watched every video I could find before buying it. All new torches sound nice on paper and even look good but until I can see it preform I will not buy it. I’m the same way when I buy a knife or short wave radio or any of my gear. This way I am least likely to be disappointed in the items because I know what I am purchasing. It took me two months of researching before I bought my 70lb compound bow. When I bought my first Subaru it took almost 6 months! After tons of research and video reviews I got the 2004 Forester XT and its been fantastic. So with all that I would have to see it first. This is what makes BLF so great because I can read what everyone else thinks of a torch I am interested in, view it and make my decision
I’d much rather just have all the emitters be neutral or warm white. The only time I’d really care for something with wildly different LEDs is something like the Acebeam X10 where there are both throw and flood options - I care much less about temp and tint for the “throw” setting (but would still prefer 5000K or lower).
There are people that prefer very cool white lights, but then I doubt they would have much use or desire for the 3000K setting. Vice-versa for anyone that strongly prefers warm or neutral white.
While it is common to find flashlights with “cool white” emitters, these usually are the worst possible color temperature choice for a flashlight, namely if used strictly at night. To make things worse, led emitters are deliberately rigged or tampered just because their output is measured in lumens which are pondered with the luminosity function, and so it is common for @#$% leds to emit light with Duv above the BBL (the amount of lumens gets slightly higher), very often resulting in ugly greenish tints or tints yellower than it should as a consequence, which is wrong. :facepalm:
Many years ago Arie Andries Kruithof performed lighting investigations describing the influence of colour temperature on visual perception, and is best known for the Kruithof curve:
While it has been criticized, as many others I sort of have to agree with his findings.
And while it is quite unlikely for me to be interested in the above flashlight, if I were to make it I would use one half warm white emitters and one half cool white, allowing for way better flexibility in choosing output CCT by combining the power at the emitters.
i would probably not be interested
Wouldn’t it be awesome to have a flashlight with an LED that has variable tint? Adjustable from 2000K to 6500K
It’s also weird that you never hear about lights above 6500K. Not that I’d want one (getting into warm lights) but it makes you wonder
Good idea. For photography I often like to contrast warm and cool lighting. Some of my photos are in my insta feed
I’m into lasers too and I think it would be so cool to have a handheld one with adjustable wavelength and a phosphor crystal to create a focusable white beam if you want like the LEP flashlights
There is at least one RGB laser available now… but it’s not cheap. World's First FULL COLORS RGB Handheld Laser by SANWU LASERS
Ha thanks I actually have several Sanwu lasers. I just got a little pocket sized 200 mw green. I noticed the strangest thing… there were a bunch of birds / ducks on a pond and when I shined the laser on a tree near the pond, they went ape**it and flew away. My blue lasers don’t provoke that reaction
