I worry about the heat……
I am using L6 with 2x26650 W/O any problems.
Because the flashlight must be compatible with 65mm to 70mm batteries, if you use 65mm batteries. It will be significantly shorter, and now I provide the corresponding accessories.
I am using Orbtronic 26650.
It’s not difficult to produce corresponding reflector. I just worry about the heat.
1S 6V 3A driver runs well my S21A with xhp70.2.
Heat is quite good on medium modes and of course it gets hot on 100% but regulation steps down accordingly.
FC40/XHP70 reflectors for M21B, S16 and S21 would be awesome.
Also XHP50.3HI 90CRI is coming
This requires customized drivers. For example, turbo mode needs to be turned on by double-clicking the switch, and the working time will not exceed 30 seconds.
Heat can be managed in a couple ways. Either by amp limiting in the driver design (permanent), or a driver design that gives you the best of both worlds:
- support max amps via a direct FET channel, or amp limited depending on the emitter used (ex: linear regulated)
- smart thermal management, as implemented in Anduril or Anduril 2
It may require high quality springs, or double springs, or bypasses.
This is why a few of us have been mentioning an Anduril or Anduril 2 option because you can get the best amps a LED supports, but with the safety of true thermal regulation/management by limiting the max temperature via an MCU internal sensor, or external sensor.
I would like to see more aggressive thermal fins on some lights as well. For example with the new 3X21A, there are many fins in the proper area but they are too shallow - they need to go deeper into the body, and if they did, it should reduce the weight as well -- another advantage.
Less aluminum mass if possible, more surface area -- good goals.
Not at all. Your drivers are perfect for it (6V/3A and 12V/2.5A)
Sorry. L7. And it does not have spring from driver side.
Ok, no spring then fuggetaboutit.
Rear spring is very small.
Actually, this model is springs-free!
Any news about Convoy 3X21A 3*XHP70.2? When will it be available?
Any update on l7 26800 extension tube?
Simon, if possible I’d like to request you to make a special run of 2-26800 tubes for your L series. Maybe a sample run? I now you’ve stated that you’ll be making extensions, however a few may prefer solid one piece tubes. Part of the Convoy success is you make a very solid product.
I would have to agree with others… an S21 with this LED would be awesome… Besides… who runs on turbo?
Are you planning on a GT-FC40 version of the 4x18A?
I would love to upgrade mine, but unfortunately the XHP70.2 is 6V instead of the 12V the GT FC40 LED needs.
When a 12V driver is available, please let us know.
I agree, an S21 with the gt fc40 would be awesome. Those wanting prolonged use with fewer heat concerns could easily use one of the mode groups with a 50% max mode.
I have build one with Tamagotchi driver. Amazing high cri pop can!
The only thing i need is 25mm MCPCB for FC40 :)
Tamagotchi driver? Do you have more info?
