What's the focus like? Is it a small spot or a broad beam?

At 3 feet from object a small 4in spot and a fainter 3ft area of illumination. Very powerful for a on AA battery light.

I have an older version of this flashlight and that one has a narrower beam. I think this newer model definitely has a broader beam, a better beam. I like this flashlight because it is very durable and I love the fact that at the end where you press it to turn the light on, it glows in the dark a bit, so it's perfect for the bedside table for those late night bathroom trips. I would definitely recommend this flashlight.

It is a little bit of both. A small spot for sure and then the light spreads out from there. Not a broad beam, however.

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

It is very bright but i do not feel it compromises the focus. My only complaint is the neck itself takes quite a bit of maneuvering in order to get it in a comfortable position.

no. you can adjust the beam to wide or focused, but not the brightness. hope this helps.

no focused beam...what light there is dims very rapidly...I guarantee that no body spotted a boat a half mile away with this light...I gave this light to my grandchildren to play with...if it was free it would be a bad deal...by the way it stopped working already and it hasn't even been a month.

It is a large , round & fairly focused beam. It is very bright on the "high" setting , and even though it is like a spotlight beam, it is bright enough and large enough to light up both sides of a two lane road . It throws the light beam out very far. You will see every pothole and bump with no problems, even if you are going very fast. It also casts some diffused light close around the front of the bike on to the ground, which helps to see up close too.

This beam does not focus. It does light up the entire field or mountain in front of you. If you want focus get another. This is so powerful though you don't need focus unless you have a special need for that. All my friends covet my Tiny Monster. Its like having like having a high end sports car but it's just a flashlight.

It's a narrow beam w 3 levels of intensity. I use it as a bedside reading light. It's perfect for that.

There is a adjustment by the lens. It can go from a narrow to a wide beam. Really a nice headlamp!

It's a microscope, so it seems to work best close up; otherwise you don't have magnification. With that said, I can focus in the lower magnification on an object about 1 meter away, but it isn't really magnified. The higher magnification requires me to be almost touching to focus. This isn't very scientific, I don't know enough about lens math to be, so I just tried it out around the room.

The beam is concentrated in the center with peripheral illumination that opens to (I'm estimating here) about 75 to 80 degrees of arc, so it gives out decent lighting to the side of the center spot. The beam is not adjustable. I've also had an issue with my EA4 getting very hot, too hot to hold, after more than a couple of minutes on turbo.

None off the above, neather summable nor focusable, its beam is so strong you would not need the mentioned. Unit comes with 5 mode. Strong, med,low, strove, sos. You would be amazed of how strong ana well build.

The light from a PAR bulb is focused. If you seek a broad flood, try a BR30 or BR40.

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.

It has good center sharpness down to about one foot. It still gets a focus down to about 7 inches, and you have to look very closely to realize that the sharpness is falling off a bit. Any closer than 7 inches, it does not focus at all, as far as I can tell.

The depth of field is very narrow and varies with other parameters, such as level of magnification, available light, etc. I had difficultly in getting entire salt and sugar crystals in focus. We found this device most useful in getting a modest resolution image of a small object up on a big monitor for group viewing, such as this lithic point shown on a 24" monitor: <http://ioccnysaa.blogspot.com/2014_02_01_archive.html> (scroll down to "Winter Laboratory Sessions" for image).

Beam area at focus = 2 cm2.power density at focus = 10 mW/cm2 for continious wavePeak power at focus (typical) = 35 mW/cm2 for pulse wave
