What is the beam divergence?

It means that the radius of the light beam gets bigger as you move away. Anyway it's the best pen light out there

It has a wide beam that goes a long distance, but it also has a more narrow beam which can go a very long distance. This helped when I was raising calves and had to check on them in the cow pasture at night. It saved many steps. I hope this helps.

I agree with 4orr. The one vertical beam will/should be adequate for what you are doing. It would definitely behoove you to do this during the early evening for the best result.

The levels of energy are so high that it would, as it is designed to do, burn out most of the equipment. To measure it in a lab, you measure the inputs, the efficiencies and calculate or use attenuation systems indirectly or reflected and diminished signal paths, etc. You would have to know from which direction the energy is coming in, what spectral composition it is, the beam width. But a simple isotropic measuring meter? Nope.

The beam pattern is not flat, it is flat from left to center then rises at about 30 degrees to the right

When focused sharply, the beam is square, and when focused to maximum sharpness it does show visible lines. I don't know if this is a result of "poor construction." If you back off the focus a tiny bit the beam is square, but focused and strong. Continue to back off the focus and you get a round beam thrown over a wider area.

Thats odd? Maybe it was a mistake. You should be able to adjust beam with tiny flat head screw driver.

The beam is exactly as pictured, with the two "legs" on each end. Hope this answers your question!

The beam is adjustable but not to the extent of the krypton versions. I find that aspect pretty disappointing. Otherwise I'm very happy with the LED mini.

It has a wide beam. It is not a pinpoint focus. It is very good for park lights on your car. Nice cool white in colour. Good product

Beam is very wide. I have it mounted under my bumper and the only cut off line is from the bumper itself. It lights up a huge area.

the front piece slides forward and backward. Forward = small beam, and back = wide

SG 47" with passive glasses - excellent results with strong 3D effect. convergence is around 7-8 foot and the 3D effect is noticeable at a much longer range than I expected. Side by side doesn't produce the sharpest images. Fantastic for the price. http://youtu.be/pEm1l7sJgHQ

I'd call it a good in between. I've got a wide beam dive light that's approx 54 degrees and one that's super concentrated 8 degrees and this leans a bit more to the narrow side but nowhere near the 8

It is a spot light, you would not be pleased with the narrow beam. However, if you diffuse it with wax paper or something similar, the beam is much softer and wider.

I'm assuming your referring to beam focus or dispersion. I don't have exact degree but this is more of a narrow focus beam. Probably no more than 20 degrees.

Narrow beam, width dictated by how far back you have it from whatever you are shining it on. Nice strong bright beam.
