The SYNIOSBEAM - CFT90 recoil thrower

Sounds impressive, looking forward to the build and first the parts list :slight_smile:

There are examples use here. Torches for the surveillance of the site SLDlaser removed. But they reach many kilometers 
 The first EDC offers” Acebeam”:http://www.acebeam.com/w10.

Looking forward to the build, nice work Enderman! :+1:

This is a very cool pic!

I agree.
Although Enderman’s light wont look anything like that with just 400 Lumens. :slight_smile:
It will be more laser like and the beam will be less visible.

I still think the Luminus CFT-90 is by far the best suited LED for this project.

Couldn’t agree more.

I have done research which suggests a laser phosphor system could get much higher than 300cd/mm^2, but have done no real world tests yet due to the high cost of lasers as well as the danger to the eye.
In the future I will definitely be exploring that option, but it was just not something I wanted to put into this light.
The goal for this was LED only :slight_smile:
I don’t really consider the laser phosphor technology an LED.

Thanks :smiley:

Great idea, I will work on a comparison of different lamps.
I also have to add some stuff to the optics comparison, stuff like multi-lens is missing.

I have designed a focusing system that is very precise, some spring-loaded screws can be turned to move the entire reflector forward and backwards by fractions of a millimeter :slight_smile:
You will see in the renders I post soon.

Thanks :slight_smile:

Yeah I was surprised when I heard about that W10 getting such high lux from such small diameter.
Laser+phosphor may be the future for high intensity!

Thanks! I have’t shows any of the real work yet since I want to post all of the preliminary stuff first like parts list and renders, but I have begun working on the physical thing.

If I can find a compact 30-50A driver that fits in the light I will mod it with a CFT90.
Currently the only drivers I have found that can do that run on 120/240VAC.
I do agree the beam brightness will be much more impressive even if I get less throw.
Worst case scenario I will mod it with an XHP70.2 and see how it performs :slight_smile:
For now I just need to get the thing built first haha

See here. Can be ordered here. You can choose the current (up to 40A).

Also, Lexel recently developed a 20A driver. You could ask him if it’s possible to make a 30A one or combine two of them.

Would this light be able to shed that amount of heat? after all the led needs to be in the beam path incl. the which includes the heat sink.

Maybe a heat pipe or water cooled solution to have less stuff in the beam and shed the heat at some place not affecting the beam.

Looking forward to the build.

A 6x6 array of XD16 dies would be perfect. ~28000 lumens and 80-100 cd/mm^2. :open_mouth:

BEAM SHOTS!! :partying_face:

Too large to fit inside the light, unfortunately.
I only have a few cubic inches of space due to how compact everything is inside.
When the light is finished, if there is no 30-40A driver out yet I will contact Lexel and see if he can custom build one for me.

You’re correct, LED cooling is very important but also hard to do when the LED is floating in front of the reflector and trying to block the least amount of light possible.
It is liquid cooled :slight_smile:
I’ll post the parts list tonight and renders tomorrow.
If I used the Synios DMLN31.SG I might have been able to get away with simply using heatpipes or directly attaching it to the aluminum, since it only uses 4W.
The higher temperature will probably reduce the candela though, even if it doesn’t overheat.
I might test it anyway though.

That’s not a lot of CD :frowning: but 28000 lumens in a spot does sound kinda cool :slight_smile:

Use your imagination :slight_smile: It isn’t even built yet! xD

Should be interesting :+1:

Not a lot of cd, but it should be a bit more than the sliced XHP70.2.

The XHP70.2 without slicing is almost at 100cd/mm^2 though?

At least near the peak of its performance.

I still think the CFT90 is the best choice for throw+lumen output :slight_smile:

That is not taking into account the effect of the cross on throw from a reflector. The cross between the dies always takes up some area in the reflector, reducing the effective luminance. Though the XHP70.2 is better in that respect than the first generation. Texas_ace measured the sliced XHP70.2 at 6A (12V) in the BLF GT at around 65 CD/mm^2. I present you with Giggles, the most hardcore BLF thrower in the World. - #101 by Texas_Ace

I agree the CFT90 is in another league of brightness and output.

The cross doesn’t affect anything, all the light from the dies goes to every point on the reflector.
There is no “taking up part of the reflector”.
The result is simply that the lux in the center of the hotspot is not as high as the lux slightly to the side diagonally, where one of the square dies would be projected.
This is only for short distances though, far enough away the four beams from each individual die will have diverged enough that all the points in the hotspot have the same intensity.

65cd/mm^2 at 6A definitely suggests over 100cd/mm^2 at close to 20A.

That’s 6A in the 12V configuration.

When I look into the beam of a C8 with sliced XHP50 from 7m away there is always some area of the reflector filled with the dark cross, in the beam center and anywhere in the beam. What you say about going slightly to the diagonal makes sense, but have you observed this? In my experience with the four die LEDs it is always like I describe above.

Oh I see, so 12A 6v.
I haven’t tested my XHP70.2 in a reflector yet, but from the modded GT beamshots there is pretty much no cross visible.
Anyway, I’m just concerned about lux, not how visible the cross is.

Since the light will still hit the entire reflector the lux will be the same if you measure it where the die projection is.
As you can probably imagine, if you just take a single die LED and move it a bit to the side you will still get the same lux because the LED has the same surface brightness and the reflector has the same area.
It’s just that the spot with the highest lux will be slightly over to the side off centre.

Well, sometimes our imaginations are wrong. :wink: I’ll just let you try it out.
