Ordered one in 3D, I’m also interested in one in SST-20.

Congratulations to the team for a successful completion to this build Beer

I know it was said a little ways back, the thread is hot and everything gets buried fast, but ToyKeeper? Cool white eliminates a target downrange better than warm white. I’ve got pictures proving it with both emitters in a GT hitting a water tower at 1.9 miles, in a light rain. I’ve got pictures both looking down the beam and from the side at a closer range (I drove to within a few hundred yards of the tower and shot photo’s from off line right, very plain to see that the cool white was putting more light with higher resolution on the tower.

Your test was biased on so many level that it made me “cringe” and in science an example is never considered as a proof or a demonstration.
“I can prove that a bullet isn’t lethal”…by shooting a part of the body without arteries and vital organs.

On earth ground, the lower the angle between the observer and the beamlight, the higher the rayleigh back-scattering. This applies to molecules (air), not particles (dust).

Source (link edited).

Which means that if you are holding the flashlight in your hand, you will have more Rayleigh back-scatterring than someone that is far away on your side. You will have less back-scattering when your are taking a picture on the side of the lightbeam than if you are close to it.
The farther on the side you will be, the better for your demonstration.

The rayleigh back-scattering intensity is greater with short wavelengths (blue) than for higher wavelengths (red), then a CW LED has more rayleigh back-scattering than a WW LED.
It also depends of the spectrum wavelengths absolute and relative intensities.

DB Custom wrote:
At long distances high CRI is really irrelevant…

CW LED has more blue light absolute intensity than WW LED, but with a higher CRI at same CCT, the red wavelengths of a high CRI LED have more intensity than a med CRI LED = more throwy red.

Also keep in mind that when you are holding a flashlight in your hand, the receptor is your eye which doesn’t respond the same to a given spectrum than the receptor of a camera.

Your experiment was very interesting though but have too much relative parameters/variables to draw a firm conclusion like you did.


yes in Dale’s experiment the flashlight was held eight feet to the side of the camera so that the camera was not looking down the beam shot. I found that holding my arm straight out to my side causes a lot less scatter and “reflection“of the light (cool neutral and warm). Sometimes holding it straight arm above my head works better also because you are spilling less light directly in front of you on the ground. Also other objects in the spill or beam between you and the target are going to reflect light back to your eyesight. The warmer it is the less all of that scatter and objects in the spill interfere with your ability to see down range. It’s very easy for people to experiment themselves with the flashlight held at arm’s length off to the side or overhead especially in different atmospheric conditions. Headlights make this even more apparent because the light is right next to your eyes. A cool white headlight on a misty or foggy night is just plain miserable. I’ve seen this in cars/trucks also where are the higher up the seating position is above the headlights the less glare you get. Edit. I’m using scatter reflection and glare somewhat interchangeably here. Not entirely sure I should be doing that. Second edit. The other thing about those Water tower pictures is what is missing. What’s missing is anything in the spill.I don’t know if that’s because the pictures were cropped or the camera was zoomed in or he was up on one high water tower looking at the other one so there was nothing in the spill zone. But objects in the spill is/are going to interfere with your ability to see down range with human eyes. So there are problems with the camera experiment.

Ordered one in /A, I’m also interested in another one in SST-20 if it’s still possible

I love all kinds of lights... storm lanterns, kosmos & matador lamps, gas lanterns, tallow lanterns, flashlights, lasers, tritium vials...

I got my PM at 4:34am, exactly on time. Awesome work, TK! I ordered a 3D and a 7A and will order 2 more when the SST-20’s come out.

Thanks so much to everyone involved!

This has been talked about at least a hundred times already. The SST 20 is a cheaper LED. The XP-L HI is more expensive.

We have known for months on end about the price difference. Have you not been keeping up??

The XP-L HI is not an “inferior led” either. It is a great Medium CRI emitter.


Excellent response. Excellent restraint too. I would have had a tough time not being more punitive! Thumbs Up

If I’m not too late, interested for 2 thanks.

The premise goes well beyond this thread. If you look at any multiple emitter option lights for sale, you’ll find that SST-20 is not a pricier option. So someone coming along as a new member and declaring XP-L HI inferior, is extraordinarily ignorant. To make it less so, they could have framed it a very different way, first admitting their lack of knowledge, then stating they didn’t understand why the price difference by emitter and if someone could explain it or point them to a source to read.

Since we aren’t closed yet, I’ve ordered my first, have reserved a second for hi CRI. May want a third when I pick up number two. So if necessary, I’d like to list for a third. Thanks again guys! Beyond excited!

I’m an old member and declare the XP-L HI inferior to the SST-20 in several ways (throw, CRI)…except for its price. Big Smile

Do all Carclo 3 LED optics fit?

This looks very interesting:

Just ordered my first one from Nealsgadgets, hallelujah it’s been a long wait. Many many thanks to all the people involved in donating their personal time and expertise to this project very excited to receive my first light. Will we be PM when the sst-20 emitter is available to order?

Thanks to the team for gettimg this over the line. Ordered a 7D, looking forward to the warmth! Probably like one of the other emitters too, please add me to the list again if necessary (was only down for 1).

Yes, all TIR lens from the same series (105xx) which share the same footprint, diameter and heigh will fit. Have fun with swapping and experimenting, first step to modding.
(Check each one’s PDF and compare dimensions if you have a doubt).

Er, I enjoy little puzzles like that anyway. I doubt everyone does though.

Like, we were watching a sitcom one night and they posited a puzzle. So when the show was over, I went to go work out the answer. I ended up staying up too late because it was trickier than expected, but by golly, I finally found a solution.

FWIW, the puzzle was this:

  • You are presented with a set of twelve identical diamonds, each one extremely valuable. Same size, same shape, same color, everything. Except one of them is fake, and it weighs more or less than the others.
  • Along with these, you also have access to a balancing scale — the “scales of justice” type with two hanging platters, so it can only tell you which side weighs more.
  • If you can determine which one is fake, you get to keep them all. Otherwise, you keep none of the diamonds.
  • You can only determine the answer using the scale, and you can only use it three times.
  • You must decide exactly which three measurements to make in advance, before you have actually measured anything.
  • You don’t actually get to touch the goods. Someone else does the measurements and lets you see the result of each.
  • The diamonds will only be given to you if you can prove that your method always works. They won’t give you anything if you guess which one is fake but can’t provide a reliable algorithm.

So, how do you figure out which one is fake?

Oh, and then they add in one more detail: If you like, you can double your payout if you attempt the problem for thirteen diamonds — but in that case, getting a wrong answer will land you in jail. So there is a harder version for those who are willing to play with higher stakes. Everything is the same except there is one more real diamond in the set, and you can also use one dummy weight which has the same mass as a real diamond.

Any ideas?


Dammit TK I thought you were a nice person. I just stayed up an extra half hour trying to work that out Glasses . I reckon I’ve got the answer but I’m not about to try and type it out. I took pictures of my scribbles though. I came up with 4 scenarios.
