Question: what is the total lumen output?
Document: So you get a charger with this and they advertise the batteries are supposed to come, I order some for over $30 and they will not work! Total ripoff! Then I tried 8 rechargeable CR123s and they will not work. When the blue light blinks rapidly it is not working. You cannot use rechargeable batteries. The charger is totally a waste and a lie.You have to use rechargeable CR123's and you will have to buy a charger because the one that came with the flashlight will not work.
Coming from a flashaholic, this is my "current" favorite light. It is bright, even brighter than my Olight SR90 intimidator. The Olight is more of a thrower, and thus illuminates farther than the TM15, but to my eye not as much total light. What I love about the TM15 is that it is very small. Quite amazing how much light comes out of a package that is so small. I like the user interface too. Takes a little bit of getting used to though.
I purchased this light with an external nitecore charger and 4 nitecore 18650 batteries. When the light arrived I charged the batteries overnight in the external charger. I installed the batteries and was impressed with the overall construction and materials that make up the flashlight. The light output and size of the flashlight were impressive. The microprocessor that controls the flashlight however failed after the first use. I left the flashlight unused overnight and the next day, with less than 1 hour of actual use the batteries were dead.
As of now July 2013,there is nothing else like it. The brightest, smallest most versatile light using four 18650 batteries. Light output is instantly adjustable with one hand. 350 lumens max brightness and 3 lumens at the lowest setting with three settings in between. Also strobe, beacon and SOS. The illuminated two step button switch takes some practice to become proficient.In a light with such brilliance and high battery capacity a truly low setting, in this case 3 lumens is an almost unheard of option.
this is the brightest thing I can find that does not require 2 hand operation. It puts my car's headlights to shame. amazing led light.
You get a decent throw as well as a lot of spill. I can turn the lights off in the bedroom and set this light on the dresser, set it to the highest setting and the entire room is lit up more so than if I turned on both lamps. Crazy bright!! !
Without a doubt, the most amazing flashlight that I've ever owned. A powerhouse in a flashlight that fits in your hand. The switch system is very effective and works perfectly. I've loaded mine with 123 cells (I buy them in bulk,) and i'm very impressed by the Tiny Monster TM15.
This thing has some hype from the manufacturer, and some favorable reviews on respectable forums [eg candlepowerforums]. So, does it live up?Oh. Hell. YES.For intense, detailed, knowledgeable technical review and comparison to other Nitecore lights, see the review by "selfbuilt" on candlepowerforums at [...]. That guy is the best flashlight reviewer in the world.
This light went beyond all my expectations. It is by far the brightest flashlight I have ever seen or owned.
This light is almost better all the way around than the first tiny monster. It is brighter, but this new light has considerably less peripheral light l guess you could say. The flood effect on the first light covers almost twice the area than the new one, which is something to consider. I like being able to see as large an area as possible. I think its because the lights are set deeper than the first one.
Answer: yes
