Please clarify that 300-Lumen Flux is for each unit or for 3 units put together giving total of 900-Lumens.

I can tell you they are pretty bright. I believe the company would have to verify that each is 300lumen.

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/

Hello my friend Ernesto, According to the LED standard, the Lumen Flux for LED lights should be 90-100 LM/W. As this is a 3 Watt LED downlight, according to our test, this light have 360-400LM, can replace 25W incandescent lamp. For more details, kindly contact Lemonbest freely. We will do our best to help you. Nice day. Regards Lemonbest

You have to purchase two more power supplies for the 3 unit option. I assume that you want the three (or 4) individual 42 LED units to be separated and not linked in a chain. To operate 3 units separately you will have to purchase 2 more power supplies at $18/each. That would give you total control of the low and high power options as well as on/off for all three units.

For the 30W unit, Zitrades lists the total (R+G+B) output as just under 1300 lumens. I would estimate the white level to be <2700K.

Not sure of the reason for the variance. From what I understand, if you use rechargable lithium batteries, you'll achieve maximum lumen output.

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

I was wondering the same thing. They don't seem to know what they are talking about. Wikipedia says there are around 16 lumens per 1 incandescent watt. A 100 watt incandescent bulb puts out about 1,600 lumens by the Wikipedia conversion, to give people perspective. I just got a 2,000 lumen Snap-On LED Worklight, which by the Wiki conversion is equivalent to 125 watt incandescent bulb (or 30 watt compact flourescent).

10,000 lumensWay more than I needed, but rather have too much than not enough.

Hi Claudi,Thank you for your inquiry! While this unit does provide a excellent illumination, we recommend purchasing 2 units for each end of the shed for full illumination. Please let us know if you have any additional questions.Best regards,Earthtech Products

This is one light. We have plenty, so 3 is no problem! Just purchase 3.Thank you!

No, these lights are NOT 300 lumens, even when using a 14500 battery. It's only about 80 lumens when using a AA or rechargeable NiMH. It's about double that with the 14500 lithium. The LED's in these lights are a few years old. They don't have the power to produce too much 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.

Not the same. Only 800 Lumens compared to 850 Lumens. May differ in other ways.

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 300 total. I strongly advise a dimmer wall switch . We like this light a lot with a matching black drum shade.

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).
