That’s true. I only don’t like XHP50.2 and 70.2 but i like XHP50 and 70 cause they don’t have yellow goo around emitter. In fact i have XHP70 4500K 90CRI installed in M21C. Just beautifull.
It means? There is no information in the descriptions. I am asking because I remember that the first batch of S21A had too narrow tubes and did not fit all 21700 cells.
Please add throw distance meters / cd info for the lights in your store, else it’s impossible to judge what to buy. Good choice to add usb charging for the new lights.
I think I’ll wait for the new version of M3 with USB-C charging and Ramping UI . Then I’ll make a decision to buy S21B or the new M3. or both of them ?
I hope Convoy will make Anduril an option for the new and updated flashlights. Also usb-c charger for as many as possible. Most will then probably chose Anduril.
The maximum output for the LH351D version probably will be a bit less than the Wukkos FC11 (FET driver), rated as 1300lm, but not very different. SST40 gets about 1600lm. Let’s say the LH351D output should be about 75% of the SST40 version output.
Edit: precise lumen measurements would require a well calibrated integrating sphere.
i have few 3V XHP50.2 LED in stock ,
I can also install XHP50.2 as you require.
It’s just that I personally don’t like the uneven light spot of XHP50.2.
There are many other COB manufacturers that are just as good but cheaper, such as Samsung and Citizen. There are super cheap Getian Opto-Electronics, but less efficient ones. I made a lamp on Citizen CLU048-1212 80CRI 3500k Verison 6 I really liked the light.
