To what distance is it 10000 lux?

According to the company's specs, your eyes should be 12 inches away from the light source and approximately in the center of the light. Also, the light screen must be tilted at a 15 angle toward you.

The description on Amazon for the Day-Light Classic (the larger lamp) says you should be 12" away to receive 10,000 lux. The Day-Light Sky will require closer exposure than 12" because it is a smaller lamp, but I cannot find any details on this. I have emailed the company to find out the distance for 10,000 lux for both models.

I don't know as we don't have outlets that are 1000 feet apart so I can't even test it for you!

Yes it has 10,000 lux. You want white light not blue. As far as the distance it depends on which lamp you buy. I bought the travel model. I set it on the kitchen table in the morning about 12 inches from the edge of the table. I read the paper and drink my coffee with it on. It has made all the difference. I use it every morning throughout the winter. Go online to Northern Light Technologies or call them. You can see the different styles online and they are happy to talk to you to answer your questions. I would have bought it directly from Northern Light except Amazon had a special price.

Usable distance with the naked eye? 1/4-1/2 mile. About the same with any good spotlight. Remember, it's a spotlight, not a floodlight out to that distance. Using use my 100mm 80power spotting scope I shine it on my buddy's house 5 miles down the valley on a clear night and see it reflect off of his cars and house.

I believe that the range is approx. 12-15 feet. After that the light starts to dim. But for the price of the 2 units, I don't see where you have much to lose.

I just read on a circadian sleep disorder clinic site that the product should give you at what distance you are getting the 10k lux. Do not see it in this product desc. Will keep looking. Thanks to others for their input.

The owners manual says it is accurate to 100' or appx. 30.5 meters. I personally have not used it for measuring that great of a distance but I can tell you it is a great tool for the price. I often work inside building with poor lighting conditions and the back lit display is great. The accuracy seems to be spot on. One of the best time saving tools I have ever purchased. I wouldn't know what to do without it!

Barabara a 10,000 lux light is only 10 to 12 percent a bright as a summer day. It might be cheery to have as a light source.Everyone responds differently to light . SAD has been a problem for thousands of years and the medical establishment discovered it25 years ago. Actually, an engineer discovered it while recording his moods per time of day. I used to point clip on reflector lights ondepressed college students... years before the discovery...some depressed students recovered.

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

Your question is not easy to answer. My idea of bright over a certain distance may not agree with your ideas. Anyway, the flashlight produces a very bright center spot dimming gradually as it spreads to the sides. At about 25 to 35-ft, that spot of very bright illumination (near daylight to you, blinding to the subject) will be about 6 to 8-ft wide spreading out to well illuminate an area roughly twice that size. I'd say the maximum range of very bright light is about 75-100-ft, but you'll still see your subject well beyond that.

It is about 10 square metre of illumination by this lamp when it is at its highest position and brightness level.

the 220 has a fairly good tight spot that goes as far as 100 feet or so, however, the farther it goes, the less tight the spot is of course. the light from the 220 can be seen from a really far distance, probably a half mile or so, maybe more. the 300, even though its output is greater, has a flood so it does not shine as brightly for farther distances.

Thanks for your inquiry. This unit has a Working Ambient Illumination of up to 2000 lux.

I dont know the exact range but my lights will detect motion at least 20 feet away

I think about 100 meters in clear, the light is very good, is a bit heavy but it does the job well.

Visible light length is 300 meters, maybe a little more, but in the dark light at a distance of about 500 meters

It was advertised to illuminate at a distance of 50'. I need it to illuminate at 10' and it is insufficient at that.
