![]() ![]() ![]() Don’t Get Wooed by Lumens-Understand Themįlashlight brightness is measured in lumens, which is a measurement of “total light, radiating equally in all directions.” Manufacturers were historically optimistic in their published lumen figures, and while many are now reasonably accurate, there are still some dubious claims out there. This circuitry has another benefit too, as it prolongs battery life. For this reason, many LED flashlights have circuitry to manage power consumption. Too much heat can damage an LED, and it gets less efficient as it gets hotter. The second way is to regulate the power used to illuminate the LED. The first is to physically draw off the heat by mounting the LED to a “heatsink,” a piece of metal, with a lot of surface area, that absorbs heat and allows it to dissipate. There are two ways to manage heat that may be employed independently or in conjunction with one another. And with some manufacturers vying to produce the brightest flashlight made, the heat generated can be significant. LEDs in flashlights, while more efficient than traditional bulbs, can still generate a fair amount of heat. What You Need to Know About LED Flashlights Because they’re more efficient, LEDs are brighter than incandescents using the same amount of power. Without a delicate filament suspended inside, the “emitter” is far more durable than a traditional light bulb. The LED itself is a semiconductor that emits light when current passes through it. LEDs, on the other hand, are 70 to 75 percent more efficient than incandescent lights. Aside from this, light-bulb filaments in flashlights are notoriously delicate, breaking when jolted or dropped. The introduction of halogen bulbs proved to be more efficient, although they can still generate a lot of heat. Department of Energy, as much as 90 percent of the energy required to illuminate an incandescent light is given off-essentially lost-as heat. Imalent claiming a 25% higher output than their light actually produces is no different than the random crap flashlights all over Amazon and Ebay who claim 5000 lumens out of a 2x AA flashlight.Traditional light bulbs are inefficient and waste a lot of energy. LOL I love the lumens war but now it’s just getting artificial. There’s a second thread buzzing about this light also.Ħ250 lumens per LED with 90% optical efficiencyĪnd it’s Imalents heat management you’re relying on to not destroy your nearly $1000 flashlight. Apart from this you have to carry a huge and heavy piece of hot metal with you. For a short moment you can flood those 10-15m in front of your feet with 100.000 (probably actual 75.000) lumens and that’s it. So, what will you get? I expect something like a bigger Acebeam X80-GT. I already discovered that the MS12 is not significantly brighter than the DX80, at least to the human eye, see my impressions on TLF: ► click here ◄ I expect the MS18 to cost more than $ 600 (without codes). The price/performance ratio is getting more and more out of control - most people become reluctant to spend such amounts of money. So, if Imalent won’t surprise us with a miracle technology it only gets worse with more XHP70.2 stuffed into this host. The MS12 becomes veeeery hot after some minutes and takes forever to cool down again. It won’t cool down the MS12 enough as Matt (“vestureofblood”) recently proved in his video review. The fan of it’s predecessor MS12 is a joke. Imalent usually exaggerates with their lumen ratings, e.g. In my opinion this “War On Lumens” is getting more and more rediculous.
