How well does it work in the daytime and how many lumens are produced?

Not sure the lumens but it is on *whenever* I ride -- day or night. On high blinky in the dark it is annoying, but during the day I leave it on that setting and it seems to get attention.

It's decent during the day, with that said nothing will keep you safe on a bike but conscious riding. It's two 0.5 watt LEDs not sure of the lumens.

This is the brightest taillight I have ever seen on a bicycle. It is made of great quality, clips on to everything, & works great. Made of good quality. I would buy this again, if I ever lost it.

I am pleased with how it works even during the day. But where I ride, I use one behind the saddle and one down low by the rear cassette to maximize visibility. As far as lumens, I do not know, but it is bright.

It's pretty bright during the day. Other's have said that this outshines most of the other lights. I don't know what lumens it produces, though

Very string in daylight. Accurate lumen ratings not available from mfr. Brighter than anything else I've seen cycling in PDX.

I cannot remember the exact lumens produced but I can say that it flashes as bright as police squad car red lights during the day. There are three separate settings and one is for continuous flashing and is great for crossing busy city intersections during the day.

Not sure about the exact lumens, but it's very bright and visible during the daytime. The unique indicator pattern is very attention grabbing.

They don't list lumens, but it's def. brighter than my 40lm Blackburn Flea; I'd guess ~60lm. It's great as a tail light. I've viewed it at 100m as a headlight in bright sunlight, and it is clearly visible; but obviously not as attention grabbing as the 150-500lm "drls".

Better than most in daylight. You cannot get much brighter tail light than these. Lumens? I don't know.

Wow! I really appreciated someone asking about this light. As long as you have a few hours of sun during the day, you'll have at least 8 hours of light at night. Install and forget! It come on @ dusk, and off at dawn. Just crawl up there, and clean the panel occasionally, to maintain peak performance. I live near a canyon in Southern San Diego, which is a natural coyote run. This light provides more than enough lumens to spot those glowing eyes, before they chow down on my two little dachshunds. Semper Fi!

Sorry, I don't know the lumens, it uses 2) 3volt lithium cells. i only use it for lighting my car locks or my pack to find stuff. the light is flood and not spot so not a huge distance. I use it frequently and have not had to change out the batteries yet, so for my purpose it is worth the cost.

well, I am not sure exact amount of lumens. But, there are 4 different types of brightness controller so you may like it.I really like this.

Hello Steve, this is not a good choice for low-light conditions. It only works in daytime, or indoors with good lighting.

I find the quality of the 9 inch LED very good in daylight, It is ok at night, but I do have a motion light on my porch that comes on and the LED will be in color making it a better picture.

It does not give the lumens rating. It is bright enough to light a dark wooded area. I have two, one placed at a shed in the woods, it lights the area well enough to see the area around the shed. I have the other one on a wooded driveway that has an extremely dark spot, it lights the area so we can walk through this area with no problems.

I think the output is about 16,000 lumens -- see ultrasunlamps com --> http://www.ultrasunlamps.com/1798

Hi there, sorry late response. This projector is very good, for presentations as well. However it's not strong enough to work with daylight, just closing curtains is not enough, it has to be really dark. In the evenings it works perfectly, even with lights on!!! I mainly use it to watch movies in the evenings, perfect! Especially the big screen, love it!

I don't have the email reply I received from the manufacturer when I asked the lumen output question. I believe it is 250 but it is very satisfactory never the less.

i think it has 250 lumens but not 100% sure. i think thats what i read anyway.

I do not have actual lumen information, just be aware this is a weak laser and you cannot see it outdoors in daylight at much over 10 feet.The switch on mine is touchy and would turn on light and waste batteries without my involvement, make sure to use the main switch and turn unit off or have a steady supply of batteries.

I don't know about the lumens. This light is plenty bright enough for what I do with it. The high setting lets me see what I want to see up to 30 or 40 ft away. I also can't say to much about the battery life. I use mine for an hr or so each morning but only turn it on when I need it. That would be 5 to 10 min at a time. I am satisfied with the battery life. All I can really say is that the light does what I want it to do and I am happy with it. Hope this helps???

I just got one, according to the seller who a is very honest person, this flashlight should be about 1000 Lumens. I just went outside to test it out on a dark place and it seems to be around 1000. Anyway, it's worth it for the price.

I cant really tell you how many lumens because i dont really know. But it's super bright. You really can't go wrong for the amount of light you get for under $10. You can just use the basic double AA wich makes it a huge plus for me.

Amanda, I know that it provides 3780 lumens, however, I do not have any photometric information at this time. That factory is in the process of moving, but if I can get anything further from them I will get back to you. Sorry -- Barry

It operates better than I expected during the day time. If it's direct sunlight, I think you're outta luck with most projectors, but this is used in our office and during the morning it's rather bright and it works fine, but is obviously better in low light situations.
