I always wanted a 10440 or 14500 SBT90.2 light but the LED always was too power hungry for that battery. Now Sky Lumen introduced the R100 LED which he says will produce 30% more output when driven hard compared to the SBT90.2. he placed it inside the Convoy T6 host.
Is this emitter just more efficient than the SBT90.2 or is it a smaller emitter so it can fit in smaller hosts?
100 bucks for a T6? Wow the Vinh tax was worth it 10 years ago when I’d get P60 drop ins from him, but thats a little crazy no matter what emitter goes in there (in my opinion).

This listing seems a bit suspicious to me as I don’t see a way to meet the throw claim. Or the output claim either.
Even assuming +30% efficacy over the SBT90.2 and 80% optical losses, 3200lm of output requires 8+A of current, good luck getting that out of a 14500 cell. Accounting for resistance within the circuitry and the almost-sure falsehood of the efficiency claim, 10+A will be necessary. The only way I can see this emitter achieving +30% efficacy is to essentially become a broad-spectrum green emitter.
Now the throw claims. The second image shows the emitter die as circular, and at least 3.5mm in diameter (the reflector opening is 5mm). This gives a light-emitting area of 9.6mm^2, which combined with the 3200lm claim suggests a surface intensity of 333lm/mm^2. This is half the intensity of a well-driven SFT25R, which does about the claimed distance in this reflector. So I don’t see a way for this light to meet the claimed 548m throw.

As far as I can tell nobody has ever accused Vinh from using Chinese lumens or anything like that. For me the only way he makes an unbelievable claim is when someone else fed him the information but somewhere lost track of the decimal point.

3200lm is possible in a size like that technically but i SEVERELY doubt the 75kcd claim. Thats almost lep levels of throw in that sizw class.

Is this R100 emitter the same one that Fireflies is using for their 900mx?
I dont know which one it is but fireflies only uses the sbt90.2 and their own ffl emitters nowadays. Some leftover stock uses nichia and osram w emitters but i dont know about this r100 “mystery led”. More details about it would be nice. I tried to search the usual culprits(aliexpress and other chinese ecommerce stores) but could find any info. It wasnt a very thorough search so maybe someone has better luck.
It looks to be the same to me. Would this LED in a 14500 host be able to produce the numers claimed?
Even if - something not mentioned here as far as I can see is the size of the host compared to the produced heat.
I have numerous lights that are laughibly overpowered for their size and get too hot to hold in under 10 seconds, which isn’t a problem because I didn’t spend $100 on them.
But to spend 100$ on a flashlight that can give you the turbo output for like 5 seconds before everything overheats is super pointless.
I just bought a T6 for myself today, including a battery 17$ or something. So just for the LED and the driver you are paying 80+$
THis light has nothing to do with the forum’s name. It is the exact opposite of a budget light.

I guess this light isn’t for you 
I don’t really have an issue with this light from Vinh, he’s building lights which takes time, plus it’s not like its insurance or food or housing or something which people need.
Personally, I’m not interested in it for the above reasons, but I don’t really care if he wants to build and sell these things at a price he charges.
If you want to make your fortune by undercutting Vinh, go ahead and build and sell some lights, what’s stopping you?
Last I checked, it’s not advertised as a budget light? It’s far less expensive than a lot of lights that are discussed on this forum.

Does there exist a 14500 cell that can continuously output 10+ amps? I’m not familiar with the state of cell technology, but my first hunch is no.
This one says 10amps is safe for continuous draw.
So i should be able to get 6 minutes of life out of it before swapping batteries lol
This looks promising. You probably won’t get maximum output for more than a few seconds though, since the battery voltage sags severely under high load (full battery starts at 3.8V at 10A).

Haha, I’m sure it has more than one mode. I think a 10A turbo will be fun, yes, for a few seconds either due to heat or battery limitations. Something like 25% would be a more practical “high” mode. 1% medium, .01% low. Hopefully the driver has a lot of range.
I’m skeptical of 75kcd if it’s an S2 (not plus) reflector like the stock T6 and a 14500.

This light is extreamly impressive. I bought a stock T6 SFT40 as a control light and the T6 R100 blows it out of the water.
