How many Lumens? or, equivalent to what wattage incandescent?
387103
I can only estimate, but I'd say it's equvalent to a 75 watt incandescant. It is plenty bright.

42 Lumens. Its quite bright. Meaning, don't stare directly into it (unless you enjoy going blind) - kind of like the sun except smaller. Technology is amazing, this includes the internet.. love your work Mr. Draper.

In general for 12V LED bulbs, multiply the wattage by 8 to get the equivalent incandescent wattage. In this case, 5 X 8 = 40W equivalent. Since a 60W incandescent gives 840 lumens, this bulb should yield 560 lumens. Keep in mind that only the upper hemisphere glows, so if used in a table lamp, most of the light goes to the ceiling. If you ceiling mount it, you get full benefit of the light.

I just looked up Lumens. Based on my calculations, these 25 11W bulbs will generate a total of 3,647 lumens. This is how I calculated it: 40W Bulb replaced with an LED = 450 lumens; 60W bulb replaced with LED = 800 lumens; 75W bulb replaced with LED = 1100 lumens. Divided all by their respective wattage for an average of 13.08 lumens per watt X 11 Watts per bulb = 145.88 X 25 bulbs = 3,647 total Lumens. I'm not a mathematician or a scientist. What I will tell you is they make my walkway look enchanted. On the box it says: 11S14 130V 11W E27 Nickel Base Bulbs. Hope this helps.

advertisement says 42 lumens, compare that to the lumens of a 40watt incandescent light bulb that averages around 400 lumenshttp://blog.nularis.com/2011/05/how-bright-is-light-bulb-lumens-vs.htmlhttp://blog.wholesaleled.com/2013/07/testing.html

The Luminous Intensity for this kind of light is around 90-100Lm/W. Then you can calculate the output lumens as the wattage you need.

I don't know the lumens but I would correlate the brightness to a 40watt flod light. I would definitely recommend the light. I have installed dozens of these lights with minimal issues.

I replaced my 11 watt incandescent bulbs and these LEDs are a little brighter so I would say they are between 11-15watt equivalent.

LED luminosity is directly proportional to voltage but 100+ lm/watt is stretching things, even for the best LED arrays, which this is not. Lumen output is probably no more than 75 lm/watt and that would be at the maximum rated voltage.

I don't know the exact lumens, but it seems to be equivalent to a 40 watt bulb however, the is very directional and would probably work for your application.

My guess would be <= 100 lumens. They say 15-20w halogen equivalent with the materials. I could believe 15w halogen equivalent.

The statement made in the description of "20W LED as the light sourcewhile lumen output equivalent to 500 Watt halogen bulb" IS ABSOLUTELY FALSE! A 500 watt halogen bulb typically has a light output of 10,000 lumens or more. This lamp has an output of 1,600 lumens, which is, as Coy said above, about equivalent to a 100-watt halogen bulb. THIS IS A GROSS MISREPRESENTATION OF THIS PRODUCT.

The halogen equivalent of a 50W Led spotlight varies according to whom you consult-- anywhere from 250W equivalent to as much as 500W equivalent! Again, this is compared to outdoor-type halogen spotlights.

I certainly think so - I'd say they are about equivalent to a 90 watt bulb in brighteness, and produce light that is closer to daylight than incandescent... 4000K and 650 lumens. I'm using 2 in an L shaped hallway with 10' ceilings, and they are actually a bit too bright for the application.

The specifications say only 24 lumens, which will be dimmer than a 25 watt bulb. More suitable for a nightlight and perhaps bad for your eyes if you plan on reading in bed.
