Why do you claim 5000 lumens when CREE, the maker of the led's says they can only produce 1000 lumens each maximum?

I was not claiming anything, merely reflecting the original advertised lumens, which still says 5000 lumen (3 x 1600 lumen). In an updated note, the bracket for the light turns out to be less than sturdy. After only 3 rides on smooth paved streets and bicycle lanes (less than 30 miles each),vibrations from contact with the ground caused the mounting bracket to fail. Though the rubber band attaching band did not break, the mass of the actual light, snapped it right off the handle bars and onto the pavement. Fortunately, the light itself was created with durable materials and survived the fall. Now I need to find another mounting bracket that can withstand the high temperature the light produces when on for extended periods of time.

Their claims seem a bit off, it's more like 1200 to 1500 lumens. Elsewhere datasheets show 67 lumens per watt Epistar LEDs and current measurements show 23W INPUT, so you do the math subtracting for inefficiencies since output must be lower than input power. It's still a good lumen:price ratio but the actual lumen range is helpful to know for comparative purposes.

Even if it were actually "lit" by LED, the amount of power used by a single, tiny LED is NOT enough to drain the batteries in any measurable period of time. We're talking at most, a few milliwatts (thousandths of a watt).

The number of LEDs is unimportant. The output as measured in lumens is what is important. That information is not provided for this product. LEDs are not all the same, even those that output light in the same narrow spectrum; design and thermal specs matter, input voltage and current matter. 9 LEDs of one design could easily outperform more LEDs of another. If you want answers, demand to know the output as measured by an industry standard like lumens or candlepower.BTW, I attempted to ask that question specifically here, and that question hasn't appeared. Draw your own conclusions why that might be. The number of LEDs is unimportant. The output as measured in lumens is what is important. That information is not provided for this product.

The retail packaging the LED130 comes in says in large letters up to 250 Lumens.The other reviewer may have had a typo on their Lumens. Since the 250 Lumens rating is printed multiple times on the box, I don't know why Amazon doesn't have it in the specs, even the Cooper website detailed specs do not list the lumens rating. All lighting products should list this in order to compare products. This is a very bright usable light, unlike some/many LED products.

These particular ones should be 2500 Lumens. The option may be there for other sellers

I have several LED type bulbs in my house, and the only ones I can get this to work with are the CREE Daylight White 40 watt equivalent (6 watt) the others I have are either not rated for DIMMER use or when in the "Off" setting the 60 watt or 100 watt version of the CREE bulbs stay on dimly.

I think the rationale behind the spec is based on the heat of a 25 watt incandescent, not its lumens output. The LED's are extremely cool in operation. The incandescent, on the other hand, converts a very high proportion of electricity to heat instead of lumens, which is why it burns so many more watts and gets untouchably hot.

It should be noted that "lumen" can mean many things depending on how you obtain a lumen measurement. At one foot away with the "zoom" at max spread the light produced 4800~4900 lux which is about 450 lumens/sq ft. Though when focus to a point the light produced over 90,000 lux which is about 8,300 lumens/sq ft. Unless you can find definitive data that explains the lumen of this light (or any other light in existence) the advertised brightness of a flashlight is meaningless. It's would be better to look up the datasheet for the Cree XML emitter and search for visual examples of the light (using quality 3.7V 18650 Li-Ion bats of course).

Hi Geoff, good question. The short answer is over 1000 lumens. The long answer is that the Falcon uses a CREE XM-L U2 globe, which according to the CREE website delivers "1000 lumens with 100 lumens-per-watt efficacy at 3 A" . Considering the supplied 18650 lithium ion battery puts out 3.6 A that means that by these calculations, the light will output over 1000 lumens. It is indeed very bright! It must be said that there is some conjecture around how lumens are accurately measured, which is why we don't lead with big claims about lumens. The easiest basis of comparison between lights would be to compare the globe specs and the output power. That should at least give you a good indication to compare. Please see the below link from CREE (the manufacturer of the LED globe) for more technical info if you'd like. http://www.cree.com/LED-Components-and-Modules/Products/XLamp/Discrete-Directional/XLamp-XML Thanks Geoff, hope that helps!

No doubt, in the product description there should be a coma between the "50000 Hrs Lifespan" and Guaranteed. I don't know any manufacture that guarantees their lamps for the duration of their rated life and would not expect that to be the case with these LED's Lamps. That, of course is only my opinion - for what it is worth!!!

Hello,Thanks for asking. This 5000 lumen is per ANSI standard. So the answer is per ANSI standard, yes.

You can get brighter bulbs that produce as much light as a 75 watt incandescent bulb and my favorites are the LED that boast of having natural light or a full spectrum light. They are a bit more costly but worth it as they are the brightest.

Maker replied me - it's in 5,000K. It's Kelvin btw. Still no words on lumens though...

The Cree LED has a usual lifetime of many thousands of hours of continuous use. The casing or circuitry is more likely to fail first.

I purchased Cree LED light bulbs at Home Depot which seemed to solve the problem. Apparently these bulbs are more efficient (lumens per watt), which implies to me less heat is being generated. These bulbs are also cast a more diffused light that other LED bulbs. Note that LED can lights are designed for the can enclosure, which is not true for LED light bulbs. Someone mentioned dimmers not working. I have found out that the dimmer needs to specify that it will work with LED lights to work properly.
