How many LEDs does it have and how bright are they in lumens? What size of batteries does it have and is it sufficient to last all of a winter night?

In order for flag to be shown after sundown it must have a light. we are happy with purchase.This baby fills the bill. Don't know the # of LEDs but,we are happy with purchase!

Stan, Sorry I don't have the quantitative data available such that I refer you to the manufacturer for it. Qualitatively, however, mine is doing a good job. Uncharacteristically we had a week of clouds and rain lately. As a result, the brightness and duration was impaired somewhat but at 0530 hours of the morning of the fifth day there was still a glow emitting from the 20-or-so LEDs. Now that we're past the autumnal equinox I expect some diminishment but we're more than likely to have clear than obscured skies at my altitude (~6700 ft) and latitude (~ 41degrees N) during the upcoming winter period.

It has 20 LED's, the batteries are AA NiCad (recharged by solar panels on top).I'm not sure about the "lumens rating" but it lights up my 3x5 flag vary well on a 20ft flag pole, and I live in a subdivision w/street lights (one 20ft away) and it looks awsome!. On a hazy-humid night (witch we have a lot of) you can see the ring of light on the ground. I'm not sure how long it stays on, as it's light when I leave for work. If you need more info, go to www.deneveusa.com.Hope this helps.....Brett Ferguson Rosenberg, TX.

It has 20 LEDs, don't know about lumens-has 3 AA batteries and the halo on the ground seems as bright at 6:30 AM as it does at 7:00 PM. So far very pleased with this product. Darwin

I just went out to count how many LED lights it has.I counted 24,my flag pole is 20 ft., they are bright enough to light my flag.A couple of weeks ago I took some friends to the airport 4:00 AM .When i got back from the airport I was amazed the lights were still on at 5:00 AM, it was still dark.I don't know the size batteries but This was a GREAT PURCHASE.They say the average life of the batteries is 2 yrs. The light fit in top of flag pole, took less than 5 minutes to put on.I have a telescoping pole.I totally recommend this light. Mark Fifer

There are 20 leds each about 2-5 lumens guessing without the proper equipment, the batteries are AA (3required) and it does stay lit all night.

It uses 8 AA batteries. If you use it frequently I would suggest buying rechargeable batteries as they tend to drain fairly quickly. I use it every night when I take my dogs out, and for me the batteries have to be replaced around 10-12 weeks for maximum brightness.

I bought one last fall and the light is weather proof and worked well all winter and is still working as good as new. I plan to add one more before winter. Stephen

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.

This one (pictured) has 9 LEDs in it with a lens over them. It's pretty bright and worked well for a while. Then it quit turning on when the safe door was opened. (This was installed inside one of my gun safes.) Figured the batteries needed replacing, nope. When I took it down (attached with heavy duty Velcro) the cover for the motion sensor fell inside the cover, don't know what happened, but I replaced it with the Mr Beam one. This has only one (new style) LED, but it's one of the new super bright (yellow when off) LEDs and it shines down on the slanted white section of the front, and reflects (some what) off that to spread the light more. Works OK in the gun safe, but can't brag much about it, and haven't had them long enough to say they last long. The light is bright, however. Hope this answers your question, know it's a long winded reply...

I'm sorry I can't say what the temperature rating is. But I can say I am using a few in a cold envirnoment and they have been fine. I have a smaller 4w LED in a an outdoor lamp on the side of the garage. Here in N. Illinois we have had about 20 nights near or below 0 and the bulb works fine. I know most cfl's cant handle extreme cold, never heard about LED's. good question.

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.

3 led's. two battery it lights up the entrance to our outdoor deck, I purchased total of 4 and have them around the whole deck many compliment 's

the maximal lumen( height 30cm): &gt;1500 lux, and set up color temperature both on cold light and warm light

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.

It uses 3 dinky coin (LR41) batteries. Since it's an LED light, the batteries are lasting longer than I had expected: 60 hours and going strong!

I've been testing mine since this question came in, 4 hours continuous use of the 3 LEDs since I turned it on (i.e. unplugged it from power) earlier today to do a test. It's still "on" and still quite bright after that time. I rely on these (I have 2 of them in the house) to come on automatically in an outage, and help me find my way to my stash of brighter flashlights and other emergency supplies. They do cast plenty of light for that and other basic purposes. If you REALLY don't want to be in the dark though, consider having additional sources of battery-powered light in your emergency kit. As we've all learned recently, it may be days rather than hours that you'll want some light.

I don't know the lumens. It is more than bright enough to light up the interior of a large cabinet. We have had it over one hear and have not yet replaced the original batteries. It's a good unit.

275 Lumens, By far the best spotlight I have had so far. I use the 4 D cell batteries instead of the rechargeable. I've never had any luck with the rechargeable batteries. They never last very long. I use it to look around the yard at night when the dog starts barking. I've had it quite a while now and still have the first set of batteries in it that I put in when I got it.

Sorry, I don't know the lumens, but I think it should be quite adequate for assembling a puzzle. We use ours to sit on the sofa and read the paper or a book, and it works well for us. If we play games at our dining room table, which has no light over the table, it's fine for that too. We just replace the "D" batteries when needed (it takes 6 of them.) Hope this helps.

3 AAA per light. If you are going to have these on for long periods of time I highly recommend also purchasing the Amazon Basic AAA rechargeable batteries and a charger. The price for rechargables and a charger will more than pay for itself over the long haul. The batteries will run the LEDs for around 100 hours, but not a full brightness, as the power drains down over time so will the light output. For occasional on off use, such as turning one on as a hand held light, or for use in a cabinet or safe for a few minutes at at time, the batteries will last months (I have had mine in my safe for eight months and they are still going strong) One nice aspect of these type of puck lights are the ease at which you can access the internals - in my case I like to have one with magnetic tape on the back to attach to the outside of the safe to see the key pad, or combination lock. I do not want to ruin my night vision so I access the internals of one, and color over the LEDs with a red marker pen. This makes the light output red of course which is much better if you want to remain in a somewhat dark condition, or are going back outside into the dark where you want your night vision in tact. Magnetic tape strips, adhesive on one side to stick to the back of the light are easy to find, most likely if you do not want to buy some just use an old refrigerator magnet and stick it on to the back, with the magnetic side clean and facing out it will stick to a metal safe. The inside of one safe I have has three shelves, each metal, I keep one on the underside of each shelf and turn on as needed, with one left to be white light for use when I do not need to keep night vision. Sorry for the long run on, trying to put to much extra information into this.

I cant tell you the specific's, but they have 12 led's and are the brightest I have seen. I have bought many looking for ones this bright. Working great for 6-7 months now.
