At what distance does this deliver 10,000 lux?

Wendy, if you go to the Philips website their have two videos showing their smaller products which they position about 6 to 12 inches from the side of the face. Based on that, I positioned the light about 12inches to the side and slightly back behind me. I have found that it works perfectly. The instructions that come with it suggest that you do not look directly into the light except on occasion. The instructions also provide positions for use. I really enjoy this light and it has worked for me. I use it about 2 hours a day.

The light power is adjustable. I don't know the technicality of it, but you should be at a distance where your eyes can look at it occasionally. You need to use it for approximately 30 minutes in the morning or afternoon.

I don't know. I think they recommend being within about 4 feet for maximum benefit. It is really very bright- too right for me once I had cataracts removed.

At full charge, I believe it releases all of its 3,000 lumens to light up an area of nearly half a mile away from you.. never owned such an intense bright device of this kind before. Frankly, I love it because I live in the middle of nowhere staying in touch with Tarzan, Jane & Korak nearly on a daily basis. I don't have to walk far to give light to a very distant object or thing. But the BIG drawback is what I mentioned before: such intense brightness only lasts 6-7 minutes, then it fades away...and dies.

Sorry, I don't know exactly, but the highest setting is so bright that on a clear dark night it probably could be seen for miles.

i'm not quite sure, but it sure doesn't put out much! Probably only 20. It's barely bright. It's useless & a waste of money!

I don't know its limit, as far as distance. However I shine it into the back of my yard, which is about 150 feet away, and it lights everything up quite well. As far as the spread of the beam, I would say it's in between a wide beam and a spot. I have owned the light for about 6 months, and I have no complaints, especially for the comparatively low cost.

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

I don't think so it's pretty bright I have mines about 8' I think it will still work at 10' if some one walks by.

It depends on your requirements. It can project to the distance of a mile... but it will be very, very dark. Google "projector calculator", and find the projector you are interested in; you'll get needed info.

tough question. How much light do you want? The light shines on my mountain 300 feet away and I can see the bushes and rocks. Beyond that I can't say.

light is awesome and very bright have transmitter on handle bars but could not tell you if it would reach 7 ft as light is under seat area. I had no reason to test that kind of distance. Sorry probably not much help.

Realistically it's usable out to about 450~550 feet or about 150M. if you need something to shine out usable light at that kind of distance you need to look into a purpose made spot light.

Scrolling over the picture, the label on the bulb shows it's 6500K lux. After searching several sites, that is the highest I've found in this shape of bulb. To get 10,000K lux, I only see it in the slender tube-shaped bulbs, or in units with two 5000K lux bulbs.

Without making a direct measurement, I would say that at about 10 feet the brightest area is about 3 feet wide,and at about 20 feet distance the span is about 8 feet wide. This light works well for me on streets at 15 mph ; I can use it alone, but I normally aim it low, close to my tire and use another light aimed straight ahead.

Simple answer, no. Not even close. It is bright, but not the advertised 1,000 Lumens.

I can't give you a technical answer but I would say that a couple hundred yards at the highest setting. The LED is a very bright light so it goes a long way.

10,000 lumens Way more than I needed, but rather have too much than not enough.

Doubt they will illuminate that far away. You'll need something more powerful.
