Excuse that I am an idiot here. I am aware that not all people are honest and many one Bay exaggerate, but I am seeing numerous sellers with many adverts now selling Ultrafire C8 1600 lumen flashlight plus others from a single 18650 3.7v cell. I have questioned some sellers, but they stick to their adverts stating it is fact. Checkout eBay tomorrow, I’m selling my old $35 pocket 100,000 lumen flashlight.
So how is this possible with a single 18650 3.7v battery,and an XM-L T6? Or do batteries run out after 10 minutes? They state 2.5 hours on full. Maybe they are a good hand warmer for winter.
Last I checked, the answer is it is not possible to get 1600 lumen out of a single T6 emitter regardless of how many batteries you use. Match did some great testing on this and got a shade under 1000 lumens running the t6 as hard as it can be run without turning it into a flashbulb.
Put simply, the ads lie. Regardless of whether it is one battery or 12, a single t6 emitter will not deliver anywhere near 1600 lumen.
Whenever you see these "measurements" from ebay, cut them in half. 1600=800 in this case. I have found that is usually accurate. These manufacturers know "lumens" is a buzzword of today for light buyers and they hype their products up as much as they can.
I don't own one, but I do own an ultrafire XML c8. Maybe 750 lumens. I have zoomables, but that feature gives a loss of usable light with its cool zoomy feature.
Two 18650s might get you over 860 lumens, but that's it. Although, you might still buy and like them anyways. They are bright for all practical purposes, and regardless of some number on a ticket, you may love them. I'm looking at several now. Just keep on being skeptical.
Sad thing is.... even if people know it's impossible if two lights are side by side ,same light ,same price and one says 750 and the other says 1600 lumens ...they will still buy the 1600.
they are lying ....and they are hoping you don't know any better.
Most people don't know and do not even know where it is made or comes from. More Lumens = better!
Many (in the U.K.) expect what advertisements state is fact by law, so believe what it states. So yes most people go for the huge lumens and think that's what it is.
Others like me are more sceptical, but still hope that inside it is new tech and so will work better. So choose the higher rated in hope, and even if it is only 750 lumen then it is the same as the other so worth taking the chance.
Even you experts buy these to test and to prove them wrong, and some out of curiosity. So yes it is good marketing if not legal. It is all down to us not knowing and wanting to believe!
So hat's off to these forum sites and you guys for helping the rest of the World out. Thank you!
