How many lumens is this rated for a 3 watt led ?

I believe 200. We put 4 of these on the sign at the entrance of our subdivision, powered by solar charged battery system. They draw only .25 amps each at 12 vdc and fully illuminate our sign

I don't know but it's brighter than my 50 watt Halogen light. This is a very bright light. I love it.

The only drawback is the bulb is not replaceable. So I do now is buy a Halogen spotlight fixture & replace the bulb with LED. Better & cheaper solution. Good luck!!!

This fixture doesn't use a 3-watt LED. This fixture uses a 1-watt LED. The manufacturer doesn't do a good job of making this clear.The fixture consumes 3 watts total. 2 watts are lost in the power regulator; 1 watt is consumed by the LED.I've compared this fixture side-by-side to a 200 lumen fixture, and it's about half as bright, maybe less. I'd guess that it's realistically about 80 lumens.

a little under 5 inches long and 2.75 inches diameterAlso you may wish to look at the 9 watt version. It only offers 800 lumens but it is smaller

DLJ, I've been running mine for quite sometime. They replaced 12v 4w incandescent bulbs and here is what I can say about these. The lumens is close to a 4w, the color is slightly cooler but still warm that people can't tell it's LED. The match up very nicely to 20w equivalent LED spotlights I put on the same system. And the beauty, not one bulb has gone out yet, running daily on a dusk timer for. 4, 6, or 8 hours depending on daylight season.

I don't know the specific lumen rating, but the LEDs are fairly bright. That being said, from a distance of 3 to 4 feet, it's a dim overall glow. I planned to use it over a work surface and it just wasn't bright enough. If you are using close up of for general illumination (like a small compartment) it should be okay.

They are LED of course, so they pull little current. I am assuming much less than one amp. If you are trying to relate them to an incadecent headlight/foglight bulb... 20-25 watts is a guess. They are the brightness that you would expect compared to factory LED strip lights. However, I am frustrated with my second set of these and would not suggest them due to the quality of solderjoints and assembly.

13 lumens sounds about right. I would have guessed less than 50 lumens. This thing is not that bright for using 3 AA batteries. I would rather get a CREE flashlight that uses 1 AA.

I have checked the box, the instructions and the manufacturer's stamps on the product and I can't find any indication of the lumens/wattage. The light is a 5" LED strip and not one bulb, for example, the type used for nightlights. I was going to add a photo of the light to the product's original description but this is not an option.

The bulb is LED hence should be low wattage, but what is more important is the measure of the total "amount" of visible light emitted by a source in unit called 'lumen'and its 6.0-8.5 lumen of bright light.

It's a little over 100 lumens. Those who wrote 200 and 300, are only comparing output to generic lights that are fraudulently rated higher than their actual output.

Hello Andrew, Our led light Bar is 40PCS*3W high intensity Leds and in high grade quality and certified by CE and RoHS. But some sellers offer lower price led lights with unkown quality on amazon. Especially some dishonesty selles may offer 1w leds to pretend to be 3w leds. This unfair competition is disturbing the normal order of the market. It causes Price war. We Promise all of Led lights sold by ATC LLC are 100% as description and in high grade quality and certified by CE and RoHS on amazon. It is simple to identity the true watt of the led -- just test it by a LED Tester. http://www.amazon.com/dp/B00IOD23ZU?psc=1 Thanks for your question. ATC LLC

I am pretty sure it is very low, led's don't put out many lumens. Lumens is a measure of light humans see. Par is what plants see. I found a watt to lumen calculator online. Seems to be about 18,000 lumens, From what it says a 300 watt led puts out.

It's really hard to speak in terms of "watts" when addressing LEDs. It always comes down to lumens. I have the 24-36 Inch Marineland light and it keeps my moss balls quite healthy. This is due to the Blue light providing the specific wavelength required for vegetative growth. Rather than going forward in terms of "watts", calculate the lumens generated by the 120 watt you're told you need...then calculate the lumens generated by the lights you have and fill in the blanks with add-on modules.

The bulb is "XML". You'll find it's 1000 lumens @ 3W on cree.com by googling "cree XML". 18650's easily supply 3W.

I am unsure of the exact lumen value, but a decent 7W CREE LED should produce at least 250 lumens (can be as much at 400), and the 4x 1.5w LED's around the sides should probably produce at least 50 lumens each.I use this as a reverse light in my truck and it made a huge difference to the backup camera at night, these little lights are able to light up a fairly substantial area behind my truck at night.

Spec is incorrect. This is an LED device, which allows for a low wattage system.
