how do you figure out how many lumens a flashlight puts out with this meter?

The simple answer would be to go into a completely dark room and shine the flashlight onto the white, globe-looking, sensor. However, I have seen "readings" on the packaging of flashlights in the stores and I do not know from what distance those are measured - i.e. if you are wanting to compare. If you are measuring several different flashlights for comparison, then you will want to measure them all at the same distance because the farther away you get from the source, naturally, the readings will become smaller/dimmer. Good luck and have fun...

I am not sure what the standard/norm is regarding how far the meter should be from the light source, but I would think you put the meter right up to the lens of the flashlight. Light output decreases exponentially with distance (proved in the experiment for which I bought the meter,) but I think that anywhere from touching the lens to maybe an inch out will give you a proper reading. I would put both the flashlight and the meter sensor on fixed surfaces, then look at the reading on the LCD display. Oh, and this is important: do it in a VERY dark room. The ambient light will make a difference.

I compared the value read out from this meter to the value from the calibrated meter (note that this meter can not measure the light from camera's flash).

This meter only measure lux which can be converted to footcandles. It does not measure total lumens.

Sorry, I dont know the answer to that question. I really like the flashlight. It has all the power and brightness I could want.

13 lumens sounds about right. I would have guessed less than 50 lumens. This thing is not that bright for using 3 AA batteries. I would rather get a CREE flashlight that uses 1 AA.

Lumen measurements for any flashlight/light source are meaningless unless you have the raw data.This flash light with the "zoom" at max spread, from a distance of one foot, with a coverage area of 1.5 feet, using quality 3.7V 18650 Li-Ion bats:High Mode:*Initial lux 4800~4900 (450 lum sq/ft)Med Mode:*Initial lux 2600~2750 (250 lum sq/ft)Low Mode:*initial lux 680~720 (65 lum sq/ft)Multiply these results buy 1.5 to get a more accurate lum sq/ft number.Focused to a point at 1 foot, well over 90,000 lux (bright as the sun), but that's what makes it great. You get that visible light WAY out long away if you need it.

When you push the rubber part then, the light lights up at the top of the flashlight to let you know where it is on its program... This sounds too confusing ...so, visit the maker's web site at http://www.hybridlight.com Hope this helps.

I'm sorry, but I can't answer that question, since I never timed it. I can say that this is a super bright flashlight, with a beam of great range and width. I mainly use it to keep tabs on what my dog is doing in my back yard, and it lights up a great swath of the yard. I have been more than satisfied with the duration, and recharge the batteries about once a week, but I cannot quantify the battery light in terms of "How long does it last @ 4000Lm?". I have three sets of batteries, so I can pop a fresh set into the flashlight if its brightness begins to wane. I can say that it does not seem to have a sharp cutoff - the brightness just begins to slowly diminish.

Sorry, I do not know. I have 3 flashlights and did not keep any information but I never look directly into any light.

Maker replied me - it's in 5,000K. It's Kelvin btw. Still no words on lumens though...

The button has 3 settings that cycle thru if you LIGHTLY click it while it's on. first is full power on 214 lums, second is half power 80 lums, third is flashing strobe. A FULL click will switch the flashlight on/off.

it states a light output of 190 lumens of light which is = to a 1/2 descent flash light

I have no way of testing the actual lumen output, but it is the brightest flashlight I own right now. For the price, I love it. I use it often but not for extended periods. It's really bright even in daylight situations when you need a little extra light. It also seems to be quite reliable; I have dropped it numerous times and it still functions perfectly and I have not had to charge the battery yet so it seems there are no voltage leaks in the circuitry (had it over 1 month now on initial charge). Overall, I believe it is well worth the price.

Are you wanting to know the diameter of the lense or the body of the flashlight

Probably around 10 to 15 lumens. It's not "Super-Bright" as the name implies. It's not a bad flashlight for the money, however. I still have mine from about 2 years ago and still use it a couple of times a week.

74 Lumen Output (Estimated Max Lumen output only. Actual performance depends on operation conditions, cells used and flashlight.)

I purchased the Klarus XT11 CREE XM-L LED Flashlight on 8/23/13. The so called manual that came with the flash light says "Max 600 Lumens." The label on the Flash Light does not show any lumens description.

Don't know the lumens but it is quite bright and adjustable from dim to bright.

sorry, but i can't locate the instructions for my own flashlight. All I can suggest is to contact the manufacturer. They most likely have a website or an 800 number.
