I have a flashlight, it has a very high lumen output. When it is on high it does not last long.

It does have a "dim" setting. This setting just strobes the led, enough where it does cause headache.

What am I to search for to have a flashlight that does not strobe the led? Maybe one with multiple leds that shut off? Is this a specific type of flashlight?

  • Does the light have to be directional? If not, perhaps a lantern would be a better fit. You can find LED lanterns that are very energy efficient and which maintain a charge for much longer than a high-powered flashlight would. – Jonathan Landrum Aug 20 '20 at 15:01
  • @JonathanLandrum I did see they have very long-life on low settings, but same issue with flashlights? – paulj Aug 20 '20 at 15:15

    All my headlamps from various brands have a low setting that is advertised to last >24 hours. They are nicely dim for use in a tent in the middle of the night without blinding you or your tent mate. – Jon Custer Aug 20 '20 at 15:21
  • @JonCuster they achieve this low output by turning on and off rapidly. It's obvious when using the touch as a bike light in the rain - each raindrop becomes a short streak. It's normally a few kilohertz, far too fast for the human eye, but it sounds like the OP has one that's much slower, whether by design or failure – Chris H Aug 20 '20 at 18:15

    go to r/flashlight on reddit or budgetlightforum.com and ask for recommendations on flashlights with no PWM or high frecuency PWM. There are a few people that can still see high frecuency PWM but it's quite rare. – ggf31416 Aug 20 '20 at 22:37
