I don’t like working on other peoples things myself. I figured your response on the lines of what you mention, based on some of your comments on other threads.
Matter of fact, I noted your response prior to mine.
Maybe Vinh will come up with a nice recipe for the GT. If he does, I may get interested enough to follow through by sending him one of mine.
That last picture made me chubby. Any chance This won’t require me getting a second job to pay for it?
I would be in for research assistance.
The first one costs like $10,000
The second one I think you can find for under $1000 if you look hard enough, but only on sites like aliexpress or alibaba and stuff like that

Ok I’m seriously considering putting this LED in the Syniosbeam (after I do testing and have fun with the synios LEDs)
The 85% collection of the reflector would mean over 4k lumens in the spot and more than 10Mcd 
The main reason I would do this is to have a really bright and visible beam, kinda like those pictures from earlier.
The compromise is less throw and a less-collimated beam.
I talked to lexel and he would be able to build a custom 30-40A driver for me for only a couple hundred dollars, so this might be a good mod some time in the next few months.
I still have to finish the syniosbeam though first, haha
The_driver, a few weeks ago you showed me a link to a 30 or 40A CC driver, I can’t find the post, can you link it again please?
Thanks
Are you referring to this post:
The SYNIOSBEAM - CFT90 recoil thrower - #13 by The_Driver1 ?
It is in your own Syniosbeam thread 
.
There it is!
Thanks, for some reason I couldn’t find it xD
Enderman, Do you have any idea how many kcd could be achieved in an Olight SR52UT? If you think that 500kcd is possible in the R40, I would think that the Olight should do much better in throw and heat management.
Manker u21 do 465kcd / 800 lumen with oslon led… i am very impress with it… of course i bought it from skylumen…
Oh, my R40 idea was not related to the CFT90, it would be a seaparate project using aspheric lens + wavien collar and probably a Black Flat or one of those new laser phosphor diodes.
If you want to know kcd for your Olight flashlight just tell me how large the optic diameter is, if you want to keep the reflector or switch to aspheric, what LED you want to use, etc.
Is it an easy task modding Olights?I ask because I know that they use red Loctite,which makes opening up very difficult.
No idea, never owned one or modded one.
It seems like almost all manufactured lights are extremely hard to open 
I pretty much destroyed my TK41 when I opened it.
I would use the CFT-90 LED and keep the reflector. I do not have the SR52UT yet, but the head diameter is 64mm and by looking closely at photo’s I estimate the inside diameter of the reflector to be about 60mm.
I know that lumen and throw numbers will be affected by how hard the LED is driven, which of course is limited by how much heat the host can handle. I know that 465k lux can be achieved with the Olson black flat, but I was looking for more lumens and maybe a bit more lux.
A lot of thrower fans are looking for max throw distance which, in reflector based lights, means going bigger and bigger. I am looking for 2,000-3,000 lumen and 500-600k lux in a medium size light, 2.5” to 2.8” head and 6’ to 6.5” length. I have a GT and it is a lot of fun, but I am looking for a thrower that allows me to identify things at a distance. The GT throws farther than I can really see and the resulting physical size makes the light impractical in many situations.
Maybe an Astrolux MF02 with xhp50.2 (domed or sliced dome) and Lexels buck driver at 3A/12v for about 3,500 lumen?
You get more lumens and a bigger hot spot.
I am hoping that spending the extra money for the “Mother Of All LED’s” I can cheat the size/throw ratio as we now no it. Getting 3 1/2” reflector performance out of a 2 3/4” reflector flashlight. Maybe I am hoping for too much, but who knows.
Yeah unfortunately the CFT90 would only give 300-400kcd in that light.
You need something with a bit larger head, or go with a different LED like maybe XHP35 HI or SST40
A TN42 would do that easily but the head is still bigger than 3”.
Why do you say XHP35 HI or SST-40 would throw better than CFT-90 in a light like MF-02?
It must be severely underpowered to throw as little as 150 kcd. And will achieve that luminosity with about the same power as XHP35 HI.
The CFT90 only does 200cd/mm^2 at extremely high currents, and in a small flashlight body that will heat up fast and drop the output.
The XHP35 HI and SST40 (dedomed) can do close to 150-180cd/mm^2 at lower power requirements, still get over 2k lumens and good throw.
Unless you have a giant flashlight or active cooling (or both) the CFT90 is not the best option if all you need is 2-3k lumens.
Or, if you’re satisfied with just a few seconds of high output and throw.
The only way the cft-90 will work for my application would be if it can be lightly driven to produce 2,500 lumen and throw 400k to 500k lux in a smaller diameter reflector light with a manageable heat load. I was hoping that the efficiency of the cft-90 might make this possible. I do not need it to provide unlimited turbo run time, but 15 seconds is useless. Five minutes at a time might work for my intended use.
My ideal reflector would be the 2.7” reflector in the Acebeam T21. Vinh has gotten 500k lux with the xp-g2, but only around 900 lumen. If the XHP35 HI and the CFT90 are both driven to produce 2,200 lumens, which produces more heat. I know that the CFT90 will throw better.
I know that the CFT90 produces a lot of heat if it is driven hard, but I do not know how how it does when under driven.
The intensity is proportional to lumen output.
So driving it at 50% of the lumen output (2500 instead of 5000) would give half the intensity.
That’s why you want an LED with a smaller die that gets 2000+lm when driven harder rather than a CFT90 driven lighter.
XP-L2 dedomed, SST-40 dedomed, XHP35 HI, are all possible options that are over 2000lm max.
