Is this 100 lumens? I teach a class of 60 students. Will this be useful?

the resolution is 800x600 so if you wish to show powerpoints, or anything students have to read on it ,the letters are gonna be blurry if you plan to stretch the size to help 60 ppl see what is projected. the projector is bright but once again from such distance I doubt be enough.

Sorry, I don't know the lumens, but I think it should be quite adequate for assembling a puzzle. We use ours to sit on the sofa and read the paper or a book, and it works well for us. If we play games at our dining room table, which has no light over the table, it's fine for that too. We just replace the "D" batteries when needed (it takes 6 of them.) Hope this helps.

No, mine is 81 lumens but it is the absolute best flashlight I ever owned. Absolute versatility and power. This flashlight seems to have a built in brain and you will soon know what I'm talking about once you start using it. This flashlight could even save your life someday, it's that good. I use it for work, I use it for fishing, I use it when fixing my car, I use it when I walk at night, just carry it with you everyday and you will find out that it paid for itself in no time. Uses rechargeable batteries flawlessly.

I don't have a lumens measurer... but it's bright. I would give it 1000 for sure! if you can tell the difference you play with flashlights way too much.

The unit or package insert do not say what the lumens are; I am not certain if LEDs are measured in lumens or not. There are two settings...one for high and one for low. I find that the high is very bright and sufficient to cover two - four pages of music. I've tried other portable music lights, but I really like this one. Hope this is helpful.

Hello,Thanks for asking. This 5000 lumen is per ANSI standard. So the answer is per ANSI standard, yes.

I would say that the light output is fairly impressive. To me the lumen output is around 60 lumens but its a fairly wide beam. The beam pattern is somewhere in the range of 160 degrees as it spreads out pretty fair. Ay other questions just ask.

the box states that it is rated at 617 lumens. I agree with the previous post that is about that of a clear 60watt bulb or just a little less. very good fixture. I recommend.

I don't have the email reply I received from the manufacturer when I asked the lumen output question. I believe it is 250 but it is very satisfactory never the less.

Amanda, I know that it provides 3780 lumens, however, I do not have any photometric information at this time. That factory is in the process of moving, but if I can get anything further from them I will get back to you. Sorry -- Barry

I looked this up and it the 170 lumens is not so. This lantern provides as follows: High for brightest light; 340 lumens; runs 30 hours * Medium for bright light and longer run times; 175 lumens; runs 70 hours * Low provides extended run times for when less light is needed; 33 lumens; runs 295 hours - Red LED (one red LED) * Red LED High - Steady (night vision preserving mode);10 lumens; runs 235 hours * Flash SOS mode for emergency signaling; 10 lumens; runs 430 hours.Bob

I think no difference on lumens according to battery or pwer But i'm not satified with this rojector cause its not very clear on the class room window light

I was wondering the same thing. They don't seem to know what they are talking about. Wikipedia says there are around 16 lumens per 1 incandescent watt. A 100 watt incandescent bulb puts out about 1,600 lumens by the Wikipedia conversion, to give people perspective. I just got a 2,000 lumen Snap-On LED Worklight, which by the Wiki conversion is equivalent to 125 watt incandescent bulb (or 30 watt compact flourescent).

Use lumens to compare a light's relative brightness to other lights, not wattage. This light, (which allegedly outputs 3334 lumens) I'd say realistically is in the ballpark of a 150w-200w halogen light. However, this light doesn't need any CTB, has a larger surface (thus is softer), draws only 36w, and runs cool. Those are huge advantages, depending on what you're looking for. 600 LEDs. Google "cn600sa" for more info. It's a generic light from China, sold by many vendors.

I don't have actual lumens, but I can tell you for a fact that it is BRIGHT. I typically keep it on the low setting. What is especially nice is the wide angle of illumination; You can open up several pages of sheet music and it covers them all. The only thing some people may not light is the color temperature. It is a clear white light, without the amber hues of tungsten.

The info. I got was 500. I have no way of testing it. At 500 or 600 its still super bright. I saw a test where it beat a 800 lumen light.

I don't know the exact lumens, but it seems to be equivalent to a 40 watt bulb however, the is very directional and would probably work for your application.
