Is the rated lumen output for one light or for both combined??

Both lights come on at the same time. It is a very bright white, far reaching amount of light.It is an excellent choice for most applications because you can point the lights in different directions.

I'm not sure about the lumen output rating, but our backyard is over 200 feet deep and 80 feet wide and this light fixture is brighter than any other light we've had!!

Both combined lights. I am pleased with my purchase. The light is very bright and I live on a street with no street lights.

I believe they rate them as both combined for a total amount of lumens for security light.

One light, they are showing three views. The light does work really well. Very reliable.

This might be too much light. You may want to buy a 3w as well so you can see which one give you the light you want.

This model is 500 lumens. I doubt you would be able to tell the difference between the two different powers.

Mine works great for any situation. I would do 250 lumen. The more light, the better traffic will be able to see you.

It's for one single light. Well worth it. Have on boat trailer and cargo rack. Awesome lighting.

Yes that is right. Because of the lumens it guves. Dont get confuse with watts..its the lumens equivalency.

One lights is fine. You can go to the web site of trulummen they have more detail info

Not necessarily. If the two bulbs are close together, the light will be brighter but not necessarily "double" the output of one bulb, because there is some cancellation involved due to proximity. Separate the bulbs some distance and there will be more light in the area being illuminated but the illumination will not be the same as if you used one 10000k bulb. There are formulas to determine this but I am not up on them.

Unfortunately I do not know the answer to this question. And I would add that the light was not as expected product., I thought I would have more light.No part of this product, lumens is not much explanation.

The product description says that these are 72 lumen total. The LEDs are 3528 SMDs which output 6 lumens a piece. If you're planning on building a flashlight, my advice would be to use a Luxeon or CREE LED instead; these tiny SMDs just don't put out enough light per square inch. On the plus side, they're dirt cheap, so if you're on a budget then this is probably a good choice.

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.

Since they sell a 10 W 900 lumens light for half the price, I presume that the 1800 lumens is for both of them, as together they draw 20 W. (would have been cheaper to purchase two singles though, since one is 30 bucks) see .LEDSTORE 10W CREE High Power LED Work Light Lamp Off Road Bike Motorcycle 2" 30 Degree Spot. Looks similar? There is a nice customer picture with one mounted too.

It's not a matter of brightness. Both emit the same # of lumens. It's a function of the light spectrum they emit. So it's really an aesthetics question. Some people don't care for "white" that's in the 5,000K range and prefer the "warm" or yellowish light emitted at 3500K.

Odd, my 12v model only had 2 wires, Brown and Yellow, and being 12 I didnt think it mattered which was which, but generaly, I chose the brighter of the two(yellow) as the +, and installed an in line fuse, works fine, bright as hell. Id rate it at nearly 1000 lumen when connected to my Deep Cycle 12v Boat battery.

Light is set up to work for both, was 4 tabs you must turn out to mount, they are turned in for shipping, I am happy with my units.

Technically one, since it only has one connection. Light equivalent is probably more like two.
