      • When temperature exceeds 55°C, driver automatically reduces current to lower heat output

      • Note: This only reduces heat - flashlight surface may still become hot

    I placed a large order with Convoy, including several flashlights: 3×L21B and 3×M21B with different LED models, plus accessories like diffusers, holsters, remote switches, batteries, etc. From start to finish, the service provided by Simon’s shop was excellent: Simon always answered my emails, whether for advice or special requests. He arranged fast shipping with DHL, immediately shared the tracking number, and provided the necessary documents for customs clearance. This was not an easy task since the package was delivered to a small island in the Pacific Ocean. The flashlights I received are perfect: powerful and exactly as described. The accessories fit perfectly as well. I can’t wait to use them for night hunting. I had only read extremely positive reviews about Simon’s shop on specialized forums and on Reddit. As you can guess, I also highly recommend this shop and its products.

    Excellent light and fast response from Simon 👍. Accidentally ordered the 6500k ver of the LHP73B instead of the 5000k I planned, quickly emailed Simon for the wrong order. He replied to me nicely and changed my order from 6500k to 5000k. As for the light itself, the LHP73B is clean for me. No rosy tin or green tint. It will be replacing my old edc the Sofirn sp33v3.

    Flashlight is a very good compact size. I like the first mode grouping because it has every single mode in it and memory mode is perfect and it’s like super bright

    Just received mine, with SFT40 emitter. I love it and amazing for a pocket thrower. Communication with Simon has a fast response to all my questions. Still planning to buy another model in the future. Last 2018 bought s2+ was bought, still working up to now. This brand is durable and fully supported by Simon.

    Additional information to add to my review below. I finally was successful at entering the modes and tried several. Mode 8 is my favorite, as the highest level is 50%. By my calculation it's 4000lm where it holds for 1&1/2 minutes then ramps down to 1800lm at 2 minutes and held there to 15 minutes more before intermittent flashing signaled a low battery. I had been using this battery since yesterday and had 3 flashes on battery check on a previous mode, so it's bound to go longer with a full charge. It did get quite warm, but I could hold the head without discomfort. I'll use this mode for a while, knowing that if I feel I need 100% I can change it in minutes.

    I received my M21B yesterday. I ordered the orange flashlight with LHP73B diode and Molicel P45B battery. Using my diy light box I came up with the approximate readings as follows: 0.1%=1lm, 1%=100lm, 10%=1000lm, 35%=3000lm. I could not measure 100%, as it's beyond the range of the lux meter in the box. It's extremely bright, though my M21G with the LHP73B is slightly brighter at 200 meters at night. Both have a well defined spot that throws and a blending flood. Even though both have the same LED the M21B is noticeably cooler, but I ordered both in 5000K. I'm not sure why. I'm still wrestling with the 20 taps to get it to go into the program mode. It is stable at 35% for two minutes, then slowly ramps down to 10% and holds.
