Is that 10,000 lumens total, or per bulb?

I believe it is total effective output --- not per bulb. Here is the description of the bulb itself: The GE F24HO/24W/865 6500K Blue T5 grow light is perfect for the vegetative period of indoor plant growth. Producing 2,000 lumens with only 24 watts, this high output (HO) fluorescent lamp is also a great energy-saving alterative to metal halide lamps. Pair these lamps with one of our 2-foot fluorescent grow fixtures for an ideal, high-efficiency grow setup.

Luminous flux = 900 (lumens) according to the specs on this bulb. To better understand luminous flux, please refer to http://en.wikipedia.org/wiki/Luminous_flux

Not sure what page you are looking at, but the box that the bulb came in says 1100 lumens. They are plenty bright. Considering installing a dimmer switch to dim them down a little.

The bulbs are each 50W (equivalent to 250W of output) for a total of 500W illumination combined. Thank you for notifying us of the error. We will update our ad. Have a great day. Steve K

Depends on the bulbs. The ones it is shipped with puts out 40,000 initial lumens.

1300 lumens according to the description. I've had the bulb replaced already with something brighter. It lasts long and work great, too. And it's cheaper.

Dear Thor, Thanks for your interest in our item. This item has Wattage: 10W/bulb (10W incandescent light bulb) Best regards, Astra Depot

10x is how many come in the package, they're good bulbs Could be a little brighter for my taste but all around well worth it :)

Not that I can see, but who cares. LED Bulb should last ten thousand hours plus, And for the twelve dollars I bought it for, I think it's a bargain!

No the total wattage is not 100 watts...max wattage is 100 watts per bulb for 300 watts max

10W * 100 LM/W = 1000 Lumen (but this does not account for dispersion etc.)But, let's say current draw yields only 6 watt, and let's say efficiency is less at the 90 LM/W, then this gives 540 Lumen. A 100 W incandescent (bulb that is becoming obsolete) is about 1200 Lumen.To really account for dispersion of light and other factors, divide each of these Lumen by about 4. Incandescent rates about a little above 300 Lumen.

Ah, it's $10 more. I payed from $10 to $12 for the 30 some FEIT 60W comp omni dimable bulbs I bought. DO NOT PAY an inflated price.

The actual package mine came in says: 8 Lumens (Although it appears to be in reality closer to 30 as mentioned by the previous commenter.)

Scrolling over the picture, the label on the bulb shows it's 6500K lux. After searching several sites, that is the highest I've found in this shape of bulb. To get 10,000K lux, I only see it in the slender tube-shaped bulbs, or in units with two 5000K lux bulbs.

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

The manual that comes with it does not say. Nor is that info on their website. However I have bought 3 other brands which do list the amount of light they produce so I can make a comparison of sorts. It it at least as bright as the light that claims 10 lumens (maybe brighter) but it is Not as bright as the one that claims 40 lumens. So somewhere in the 10-20 lumen range I think.

They are actually 865 lumens. I like the 4000k bulbs, I am not a fan of the yellow look. The cool white also tend to give the room more of a daylight look I find.
