If the lense output is 10 degrees, what is the efficiency of the lenses? I bought some "spot" LEDs where the 10 degree pattern looks like a flood.

This item has the biggest reflectors in the market for best spot beam, It will not look like flood.

These have a flood beam that I would say is about 90 degrees... the light is very cool in temperature, perfectly diffuse, no hot-spots. This is not a SPOTLIGHT. It is a work light. Doesn't throw very far, but has I wide beam.

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.

I'm not sure. I use them for low voltage outdoor lights. I can say that the angle is fairly wide, so not 10 or 20 degrees.

This is not a spotlight, the output is pretty uniform, and there are no visible "hot spots" in the lens. The lamp is supposed to be equivalent to 65 watts, but it appears brighter than that.

Measure your lens. My lens was in the 38mm range +/- 2mm (kinda hard to measure with it installed in the lamp). FYI, between my son and I, we have 4 of these. I prefer the wide angle lens for single LED lamps. I ended up taking if off my three led lamp because it made the beam very oddly shaped. But it works beautifully on the single LED lamps completely eliminates the hot spot in the middle of the beam.

spot beam, 1500m! PLS be aware: "All Good LED" is NOT authorized seller, ship copies!

I just did a project where I set up a set of 10 lights (one 300 tape in 10 pieces) with the furthest approximately 50 feet out. Splicing into the line where needed. There's no significant brightness drop along the line. I didn't measure voltages though if you're looking for precision.

Previous responder has it right. The pinspot came with a 6º lens (installed) and 9º lens (a spare). I have it about 10' from it's target, and the 'spot' is probably about 9-10" diameter -- twenty feet would be about a 20 inch spot with the installed lens. The 9º would give you a wider spot. The further away, the wider the spot and the less intensity. The only way to adjust the beam is by replacing the lens. There is no other adjustment. BB

Mine was snowed on this week. Eventually with 3-4" the light melted the snow.no issues with broken lens.I like the look .much nicer than my old ones I had fluorescent in.

Don't forget to manually adjust the aperture (the adjustment ring on the adapter). Wider aperture - > more light gets in.

You can change the angle of the light every 10 degrees or so. You really only need to aim them straight though. They are super bright

The beam angle is definitely more flood light than spot light. Don't know the exact angle, but would estimate 45 degrees

It should mean the amount of focus or concentration of light that is spotty which would be more the 30 or diffused and broader which would be closer to 60 degrees. You should check the laws in your state for where you can mount these lights. In NY I believe you can use these for off roading or plowing driveways but not on the highway. Anything mounted above your original headlight even the hood may not be used on the highway. Therefore 30 degrees would be less in the eyes of on coming traffic but 60 would be definitely in their eyes. It would look brighter to them but you would see further in the dark with the 30 if that makes any sense?

I believe you (ranthon007) are operating under a false assumption. Regardless of what image size you choose to use, the actual physical pixels on the sensor must necessarily remain the size they are, and if that's too small to let in the ideal amount of light, well then you're stuck. I'm not sure whether smaller output sizes are done by rescaling or by simply using fewer of the pixels (i.e. not the whole sensor), but while you MAY be gaining some reduction of noise, there is NOT an actual increase of detail.(Anyone please correct me if any of the above is in at all incorrect!)

No way. It's not bright enough. I use mine for photographing rings. I shoot at iso100 1/100th at f10. I have two of them. They are placed 8 inches away from the rings. If I moved the lights to 2 feet away, you're probably looking at f2.8 at iso100. So, to answer your question, in daylight....you'd probably need 10 of these to be seen. :-)

About 45 degrees ... I had to use two to light up an area about 30'x10', mounted 8' up and 10' apart, with the camera centered about 4' above them
