How bright the LED flash when it is ringing ? Good enough to see it from far ?

It is a very bright strobe. It is visible from Any location. If this were in a large Office complex it would be visible. We purchased two for deaf person. One in kitchen one in living room.. at night They light up the house.

Yes, the strobe is very bright. It needs to be placed in an open area to really grab your attention.

It is fairly bright but for somewhat close work. It certainly is cheap enough for a try!

I can't vouch for the lumen rating, as that would need a good detection instrument, but it certainly is very bright; not as powerful as a car headlight, but certainly good enough to see ahead when moving at speed. The only drawback is that this power comes at a price...battery life. I would suggest spare battries be bought and carried for extended use.

If you mount it on a wall at least 7ft from the ground it will be fine. It's very bright but you shouldn't be looking at it anyway.

It's pretty bright, but 20 feet would be *really* pushing it, I think. Of course, it depends on what kind of camera you're using, and how good it is at high ISO. From that far back, though, the light will also be pretty concentrated, perhaps not all that much different than a flash, in terms of shadows and such. Bottom line, I don't think this would do what you need it to.

It is bright enough as long as you have additional ambient lighting near. I have a 3 light fixture above my wall mirror and a small led spotlight in the ceiling above. This mirror has worked out great for me so far.

it is a bright flash light but if the lake is not completely clear it will reflect back at you. I suggest diving for it

This light is bright but I point it down, 10-12feet in front of me. No car has flashed their lights at me so it must ne okay. It projects a white light in the center about four feet. The radius of light is enough even outside of the four feet. I've only used it twice at night and so far I like it.

honestly you won't even notice it. the LED indicators aren't that bright. i thought it was going to bother me but it's not even an issue for me or my wife.

I use mine in the office and the buttons are bright enough to be seen across the office about 12 feet. There are not super bright but very functional.

Bright enough for that though your mobile phone probably has a brighter light. It doesn't throw more than 2 Meters.

It seems bright, but at a distance of 4 to 5 feet you'll be shooting at f/ 5.6, ISO 400 And 1/30th to 1/60th of a second. Diffusion would make it almost unusable. Send me an email and I'll send you a photo.

They are bright enough. However, I've been having problems with visible pulsating when the lights are dimmed below 60%. Not totally noticeable with the naked eye, but the pulsating appears on the video in post production.

No, it flashes between high and low beam. Makes you very visible! I highly reconmend it.

I find it bright enough. It's got that incandescent warmth. If you want super bright this isnt it. It is very quiet.

It is very bright, which makes it suited for a bicycle light. It is bright enough to help you see where you are going. Hope this helps.

On high beam I've taken a 1.5 hour ride and it was still burning bright at the end. When on flashing I've gone over 2 hours with no problem. Without a meter on it I don't know how long it really lasts. I've gotten to really like the light. On high my field of vision in dark, country riding is I'm comfortable riding up to about 19 MPH. When there are a lot of critters running around I do slow down to about 16 so I have plenty of time to swerve.
