Can anyone tell me how many lumens this bulb gives off please?

I've used these for the last 3 lears growing plants they are between 5500-6500 lumens. What is your application?

lumens are not written on pack. But based on general formula it is around 3000 lumens. You can find formula here ..http://www.efi.org/factoids/lumens.html and http://lumennow.org/lumens-vs-watts/

I'm not sure of the lumens. I am using them as day time running lights and back up lights.

both comments below are wrong, the lumens would be 95,000. given the info from the ushio website you can do the math {95,000(lux)x0.0122(hps[source])=1,159(par)}. the website says 1,150 par so you can do the math backwards to figure out the lumens. this can be done for mh bulbs too by substituting the source to (0.0141). regardless this is a badass bulb that pumps out 7,000 more lumens than the standard hps bulb! hope this helps!

It's a 13W GE T5 bulb. Initial Lumens = 790. Presumably that decreases as it ages, but I don't know how fast.

8000 lumens total. 2000 each bulb. Lumens will decrease over the age of the bulbs though, so 8000 is the initial amount.

Generally, to determine brightness of a bulb check the lumens 12v LED bulbs usually range from 90 to 300 lumens. I've seen some with less lumens but do not recall seeing any that are greater than 300 lumens.Not all descriptions will show the lumens. So I will either take my chance or not buy without knowing the lumens.

Its bright enough to read by, I'm not sure of the # of lumens, it gave off enough light for the room. I had it going for approximately 2 hrs on a full charge when I shut it off, so I cannot tell you how long it would run.

The lamp is halogen (lamp type determines the conversion ratio) . So, the conversion is approximately 20 lumens per watt. I don't remember the exact wattage of the lamp it came with. It is probably 190 watts (you may check it in the instructions it came with). It is, therefore, about 3800 lumens.

All I can find is that is tis 27 watts, can't find the lumens, Sorry. Jayne

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 believe it is approx. 2304 lumens , hope this helps! Don't get hung up on the wattage of a led fixture but more important is how many lumens per watt , the better quality like Cree are setting the standards!

I am not sure what lumens it puts out other then. I put it in my 74 dodge truck and its like daylight when i turn this light on. Hope this helps

Don't know the Lumens of the light, it was not as bright as I expected, but brighter then the regular bulbs.

Exactly how many lumens, I do not know. I would guess that it is about as bright as a 40 watt light bulb. The beam is quite focused, though, so it is great for illuminating a tabletop or other surface without illuminating the whole room. I used mine to light the dinette table in my camper and it hardly lights up the beds in the camper at all. The lighting is definitely on the cool side.

I don't know how many lumens it is but the light is very bright. I love it.

The manufacturer specifies the output as 200 lumens. It is quite bright, considerably more than the stock xenon bulb. http://terraluxportable.com/product/ministar-srn/

A 100 watt incandescent bulb puts out about 1600 lumens. This light is rated at 1400 lumens. It appears brighter in my opinion due to the way the LEDs are spread out. Appears to light a larger area more uniformly.
