The SYNIOSBEAM - CFT90 recoil thrower

Nope, there is close to 0 space left!
It’s not getting hot now that it’s heatsinked well though.

RecoilBeam reminds me on those small ultrafire recoil led flashlights (UF 007, 008), and it will mess google search by bringing them into search results.

Be more creative than that :stuck_out_tongue: .

Enderbeam :smiley:

:+1:

Or maybe Enderman Endlessbeam

Wow.. pretty sick stuff here! That is impressive!

EnderFire™.

LuminousBeam™
Model CFT-90

Sick!

Awesome :smiley: You gotta find a way to “shrink it” and make it the pocket thrower of the century :smiling_imp:
Nice work :+1:

Don’t forget to machine an attack-bezel for it!

After all, it wouldn’t be “tactical” without one! :smiling_imp:

NeverEnderBeam :person_facepalming:

I kinda like the current name. It has a kind of futuristic/scientific/outer space type of sound to it.
I didn’t associate it with the led the first time I red it.

You should contact Disney so they can put this in the next star wars film as a hand held death star with the newest beam technology called the syniosbeam. :smiley:

Oh yes :slight_smile: :+1:

True, that’s why I liked how unique syniosbeam was :confused:
If you google “recoilbeam” as one word however there are no other search results, so it’s still unique!
I might go wit that, or stick with the current name.


Would rather not have my forum username be part of it :stuck_out_tongue:


Thank you!


This is a good one but I’m not sure if I want to have it named after an LED, what if in the next few months something even better comes out from cree or osram?


Thanks :slight_smile: Some time in the near future I want to mod/build a single-cell compact EDC light that can do like 1-2km or more!


Haha, just hide this tactical flashlight in your pocket :slight_smile:


Yeah it’s a pretty unique name, and the the light was designed around that LED, so maybe it would be more appropriate if I just describe why the LED choice changed mid-build.
Rather than pretending I chose a different LED from the start.
Changing the name to “recoilbeam” would still allow me to explain why the beginning LED was changed while having a unique flashlight name.
Thanks for all the suggestions :slight_smile:

FIRST LUX MEASUREMENTS:
I did a very quick test last night at 140m distance, first I got ~5Mcd, but after one quick eyeballed focusing job I got it up to 7.5Mcd!
380 lux @ 140m (measured with a laser meter and also google maps).
Since the reflector collects light all the way to 85 degrees off-center from the LED, the lux is very sensitive to focus.
.
Once I get smaller tubing which doesn’t push on the reflector edge I will do more lux measurements at 500m, hopefully this distance will make the focus have less of an effect.
Instead of just guessing the focus like last night, I will also try adjusting the focus while someone (on a phone call) tells me the lux at 500m so that I know when I find the sweet spot.
Hopefully this can get me above 10Mcd which I was hoping for.
.
If I switch it to a CFT90 I will probably still get above 5Mcd, but the beam will be 5x brighter which will be really sweet.
The focusing will also be easier since the LED is 9x larger.





Comparison to the Optofire:

You can see that the reflector removes all chromatic aberration that the Optofire had, and also the yellowish tint that the wavien collar gives.
The beam doesn’t seem much brighter though, since the intensity per area is halved compared to the Optofire (which uses a wavien collar), and instead simply has more area making the beam wider.
After getting as much candela as possible with the black flat, I will switch it to CFT90 in order to get a more visible beam just for fun.

It definitely looks more sharply focused vs the last post pics. CFT-90……can’t wait to see the beam.

Your making Giggles look like this. :frowning:

Nice, now the farthest throwing led reflector thrower ever - by a large margin!

The second pic looks really cool!

The beam looks very similar to my light, but that was to be expected (in truth it’s actually much slimmer though). The focus looks a bit “off”.

BTW: you could improve the performance a tiny bit by putting a spherical mirror into the center hole of the reflector. :smiley:

EDIT: I just checked, you should be getting up to around 11-12Mcd. You’re still way off. Like I said - focussing is very, very difficult.

Yeah, even a barely visible brightness increase to my eyes brought the lux up from 5M to 7.5M, got some tuning to do for sure.

:frowning:

Thanks!
Yeah I was expecting over 12, however to get the focus right it will require a very long distance measurement, and then atmosphere might start affecting the results.
Will have to do the 500m test on a very clear night.
The only ways to make the focusing easier are to increase the LED size, which only makes a bit of a difference, or make the optic have a larger F number so that the mirror is farther away, sort of like in a mirror telescope.
This basically would make a clear die projection like a lens does, but then I lose the advantage of compactness and light collection.
The next light I build will be a longer focal length, either reflector or lens I don’t know yet.

And yeah I bet I can get 1 extra lux from adding a spherical reflector in the middle there xD
