Does anyone know the angle of the beam? Or, does anyone have a chart showing the area of light at given distances?

The strong center spot is about +-2.5 degrees. The outer weaker spot is about +-45 degrees.

It is a flood pattern. Don't know the angle. There is an identical lamp available as a spot. I have both and there's not a huge difference in the light patterns between the two

At about 3 feet (from the illumination target) with the sleeve all the way back in flood mode, the beam is about 3 feet wide. Also at 3 feet, the beam (with the sleeve in spot mode) is about 4 inches across. Extrapolate that out to the distances you would need.

Its infrared, so it isn't visible to the naked eye. Anyone with bc can see it. At 30ft the beam is 1'

if you center the beam ( by pointing it down to be 3 ft. in front of your front wheel) I would sayabout a 3 ft circle. does this help? wish I could remember the site I found it on, as it had pictures of various lights in the same scenario, and the cygolite 420 stood out, especially in relation to price.

It has a wide beam with a defined brighter narrow beam as well. Beam width is not adjustable. Great light.

I'm not sure about the model number -- mine has no identification other than "DORCY" on it -- but it looks like the photo I see on they question. So on my flashlight, the beam is very very bright in a circle which is 6" in diameter at a distance of 6'. There is very low-level illumination in a cone that is about +/- 45 degrees from the center of the beam. There is no adjustment for beam width.

10 yards is the peak brightness. At that distance they hurt your eyes, and traffic hates me which is why I bought them for my motorcycle. I want to be seen! The exact angle I can not determine. it is a very tight pattern that does not spread out until about 45 feet.

Length of it is 2.28'', diamater is 1.97'', please make sure the size fits your fixtures.Beam angle is 45 degree, if there is a GU10 socket in your fixture and supply 100-240vac input voltage, it will be suitable for your track lighting.

To infinity...and BEYOND! OK maybe not quite. The guy "selfbuilt" has an excellent technical review on candlepowerforums.com if you search you'll find that. His comparisons to other Nitecore lights show this one as more "throwy" than them, ie it is a more narrow beam that appears to project farther than others. In my use around home, it brightly illuminates a treeline across a small lake about 150 yards away. Haven't tested it myself further than that, but I would guess that the concentrated beam I see at 150 yards would be notably visible at least twice that far. Maybe more?

I'm not 100% sure. The lights I have are listed as a fog light, so the beam is wider. I is probably close to 60 degrees. The spot lights that are listed are probably closer to 30 degrees.

spot beam and flood beam, this is about the light shape, spot beam 10 degree, and flood beam 45 degree

It has a wide viewing angle of approx. 50 foot wide, at a Distance of 150 feet, ( I measured it with my 100 ft tape) the beam would probably go farther but that is where my travel trailer and boat is. The minimum distance would vary, as mine is tilted up for maximum distance. My beam starts at 22 ft from the light source and lights up everything out to the 150 ft. I bought the first of these lights and it lasted two days before burning out. Amazon took it back, and I bought another one. It lasted 36 days before burning out.

Don't know the beam because mine never worked from the moment it came in the mail. I can't recommend this item

I bought a set of 2. At first I didn't notice, but after about a week or two at night after I installed them, I noticed that the two light have vey different beam spot sizes, or flood patterns...or whatever you want to call the illumination pattern. I measured them, and one is close to 8 degrees, and the other is close to 30 degrees. The 8 does look like a spot type. With some small amount of outside the spot light beam. The 30 is more or les a flood type light. No real focused beam. Still seems to look as bright when doing the stare test, or the 'dark garage wall test. I'm trying to contact the vendor and ask them. FYI - *** When I've looked at other sellers of LED moto lights web sites, the majority of them do mention that they sell a spot version, and a flood version.( for the same lamp type) And if you don't specify exactly what two you want in your order, they sys they will ship you one of each. That may what happened to me.

If you look directly into the device, there will be a faint res dot. You can not see any light otherwise. It will throw out to about 150 yards effectively, maybe a bit more. There ia about a 30 degree angle either side od center.
