Was wandering what "Ansil Lumens" are I cannot find any measurement in regards to projectors or light output. I understand about ANSI lumens, American

Maybe... you are right. Any way 80 ANSI (Is it ture? I don't kow) not enogh to use the projector at day. I can be used for only night.

1800 LUMENS ! ... so say my measurements (electro-optics engineer)LEDs are RED 630 nm (they say) - I see 620 to 630 nm.BLUE LEDs are 460 nm. (they say) - I see 460 to 470 nm.Uses two power supplies: Output of approx 64 VDC at 150 mA(in case you need to buy a new power supply!)This is very over-priced. Available direct from China they sell for $40.

Unfortunately I do not know the answer to this question. And I would add that the light was not as expected product., I thought I would have more light.No part of this product, lumens is not much explanation.

The lumen output goes up very slightly as voltage rises due to the regulation not being perfect, but the difference is so small that most peoples' eyes could not discern the difference. Lumen output is roughly 1200 to 1500 lumens, it is hard to compare since the beam is so floody but this is what the component datasheet suggests at the measured drive current.

Those are 2 very different measurements. Lumens are the light output while kelvin is basically the color. Expect about 600 lumens and about 8000k. It depends on how you drive the light and what type of power source you are using for the output.

I don't know the lumen output, but the light is for effect only. It is very low light. Also, the batteries do not last more than one season without replacement. I have had these 3 years and that is my main issue.

The product description says that these are 72 lumen total. The LEDs are 3528 SMDs which output 6 lumens a piece. If you're planning on building a flashlight, my advice would be to use a Luxeon or CREE LED instead; these tiny SMDs just don't put out enough light per square inch. On the plus side, they're dirt cheap, so if you're on a budget then this is probably a good choice.

Hello David, The answer is sort of technical, so bare with me. The lumen is the derived unit of luminous flux. Luminous flux is a measure of the total "amount" of visible light (as measured in the green light wavelength spectrum) emitted by a source. Luminous flux differs from power (radiant flux) in that luminous flux measurements reflect the varying sensitivity of the human eye to different wavelengths of light, while radiant flux measurements indicate the total power of all electromagnetic waves emitted, independent of the eye's ability to perceive it. Lumens are related to lux in that one lux is one lumen per square meter. Check out Wiikipedia for a more complete answer. Thanks, Glen from CampingStuff

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

I have no idea what the lumens are. However, at in the late night, when I narrow the beam to it's smallest I can see a 4' x 4' area 200' away, very clear . That is very good for a flash light with one AA battery that last a long time. S. R. Kirkley Tyler, TX

Allen, Actually the precise known distance is unknown, I did talk with the rep from cygolite and they were not sure them selves. I know that this is 360 lumens

I wouldn't worry about the Lumens. I returned them because out of the whole box only one worked. I wouldn't recommend them.

I can not tell you the lumens (you may find on printed materials provided, I have not looked) but I can tell you the light it provides me as I use it in the theatre pit exceeds any light I have used in the past. This is the best answer I can give you. I hope it's helpful...

It's a little over 100 lumens. Those who wrote 200 and 300, are only comparing output to generic lights that are fraudulently rated higher than their actual output.

Thanks for the info. I hope to goodness that the lamp life is not 3,000hrs! I've been waiting years to buy a projector that doesn't require rip-off bulb replacements. My own HS201 is on a UPS truck at this very moment, waiting to be delivered to my house...
