How many Lumens does it output?

I'm sorry I can't answer that; don't know. It is basically a spot light. I have it in a photographer's stand to point at the plants. It has to be fairly close to the plant and doesn't cover much area. The plants do like it, but there just isn't enough of it.

I don't know about lumens exactly, but I measured the output with a light meter and it registers about 15k to 20k lux (1 lux is equal to 1 lumen per square meter, I think). They say 20k lux is legit for growing plants. I ordered 4 different types of grow lights, and this actually has the highest output (including a 60 dollar T5 setup), it just doesn't cover a whole lot of area, although definitely covers more than the other under $20 LED lights. I may buy quite a few of these.

I'm not quite sure but this is very weak. I have a jalapeno plant and no progress of growing. I use 2 bulbs and leave on 24/7. May be good for small flower or herbs.

Not sure the lumens. I did have two of these bulbs stop working after only a hundred or so hours. Not recommended.

I don't know how many lumens. But the light offers two levels of brightness: normal and high. I use it for keyboard music in my bedroom, only on normal setting. I can't imagine wanting a brighter light, as that might result in glare, or white-spotting on the sheet music page? This light is ideal for viewing a page of sheet music in low-lit, or completely dark room.

I don't know the lumen output, but the light is for effect only. It is very low light. Also, the batteries do not last more than one season without replacement. I have had these 3 years and that is my main issue.

I run it at 12v, I'm 90% sure it's 250 lumens at 12v. It is very bright. I would highly recommend.

Answer 1.1 lumens at 3 feet. Good to light my 36ft sq shed at night. I like it.

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

2800 lumens. All four of mine buzz rather loudly. The buzz might be okay for a shop environment but it's not acceptable for me in an office or home space.

I cant really tell you how many lumens because i dont really know. But it's super bright. You really can't go wrong for the amount of light you get for under $10. You can just use the basic double AA wich makes it a huge plus for me.

I don't know how many lumens. However I have one in my laundry room at the top of my stairs and it lights the hallway and stairway. Seems plenty bright.

It's not very bright at all. In fact I was very disappointed with the amount of lumens actually put out. I'm thinking of replacing the two that I purchased because they're just not doing the job.

If you want to leave it plugged in to watch a movie then you'll be getting 100 lumens. If you're using it in the battery mode then you'll be getting 40 - 60 lumens.Hope this answer your question.

Not sure About lumens. But its bright enough in the dark. The motion sensor worked really well. I wish it would stay on a little longer.

The light output depends on the specific F15T8 fluorescent tube used. These are generally 15 watts, initially producing around 700-900 lumens, depending on manufacturer.

still waiting for the response.... what is the lumens. question 1 didn't provide the answer.

I do not have actual lumen information, just be aware this is a weak laser and you cannot see it outdoors in daylight at much over 10 feet. The switch on mine is touchy and would turn on light and waste batteries without my involvement, make sure to use the main switch and turn unit off or have a steady supply of batteries.
