“I used my sp36 underwater and killed it. Fortunately they sent me a new one free, but I'm only trusting my dive light underwater”
“So far my Sofrin SP36 (for lighting up a room) and SP10 (for task specific lighting) have gotten me through.”
“My 6k lumen sp36 pro can light up a field but it tops out at around 100-200m of meaningful illumination.”
“I have 2 of the lights listed here the ts22 and sp36 blf. I would recommend the ts22 since the sp36 is 3x larger in size. You really dont need a monster size light for indoors.”
“I’ve used my SP36 the last time we lost power (thankfully only for about two days) on moonlight and standing on its tail.”
“I had a Sp36 then it disappeared. I suspect it rolled away, since the SP36 is just too round and has no retention options.”
“Then I went for a Sofirn SP36 as a splurge and loved it.”
“I can tell you that the color difference between 3500K and 3000K isn't enough for me to use my Sofirn SP36 BLF over the D4SV2. The size difference of the D4SV2 means a lot more to me than that 500K difference.”
“I've previously owned the SP40, IF25A and SP36 - and the more I used them the more I wished for stable output, ended up selling them and waiting for something new.”
“I also killed my SP36 submerging under a foot of water for about 20 seconds. It fogged up next day and a few days later it died. Sofirn did replace it free also.”
“The only one I did regret was the Sofirn SP36 which is just too big to carry in a pocket and has no lanyard. The light itself was pretty good.”
“SP36 2700k BLF: On candle mode, I swear this thing drains almost no battery. It's creepy and I love it so much as a lantern.”
“My Sp36 pro just burnt up here in TN after a hot summer, plugged charging cable in last night and it started smoking and shorted out my trucks outlet too smh.”
“SP36 is great if using at medium but gets hot and isn’t efficient if you want sustained higher lumens. Mine sits by the back door to quickly light up the backyard if need be. I much prefer my sc33 for a flooder due to size driver.”
“Sofirn SP36 pro. I have one, live in Iowa, and this is exactly what I use it for. Uses the same USB-C plug to charge as my phone.”
“My anduril sofirn has a "self defense" strobe that repeatedly flashes at turbo brightness (SP36, so supposedly 5k lumen). It would SUCK to be hit with that in the dark.”
“The SP36 is a budget light. It uses a simple and cheap FET driver, which overheats quickly and forces the flashlight to reduce brightness due to the heat.”
“that's a characteristic of the SP36, every single one of them that has ever been produced, in every single spec, has this beam profile. If you don't like this artifact, you can go for another multi emitter flashlight with more LEDs”
“I bought a Sofirn SP36 BLF and assumed it would have a lot of light and good runtime. However, when I tried using it on a walk, I realized that it still heats up quickly and doesn’t cool down easily. My 5000 lumen light turned into a giant, heavy 2000 lumen flashlight.”
“tbh, my Wuben X1 has replaced my SP36. Insane amount of light in a smaller and handier package with far better regulation. Just have to lose the High CRI and battery bank part for 12,000lm (measured 10,000 @ turn on) insano' flood.”
“For me that’s an easy one, sp36 blf anytime. I have both and my sp36 blf could have 100+ hours of use on it while my q8+ would be lucky to have 10+ hours on it. The q8+ is a wow factor and the sp36 blf is everything else but still has impressive output and throw by normal standards.”
“Sp36 is the perfect back door light, lights up the entire backyard.”
“I noticed that some very dim LED's on the power button stay lit when the light is off. Has anyone experienced this? How do I turn it off? Can I even turn it off? This was going to go in my truck, but this seems like a dealbreaking design flaw as it will surely drain the cells”
“I personally rock a Sofirn SP36 for my nightrides, gets the job done but sometimes I wish it was just slightly brighter.”
