How many lumen s does this put out?

I can not say directly on account of lumen's. I will say these work great for vegatative growth. They put out plenty of lumen's for that. I wouldnt go any further then veg. I measure lumen output after 18 inches and greater thats when you get a true output number.

40,000 lumens.. each 53 watt tube puts out 5000 X8 = 40,000. I have several of these fixtures for several years and and grow and bloom very light demanding Cattleya orchids under them. This is a beautiful, highly efficient unit. You can grow orange trees under it. It does not radiate a great deal of heat, but the light can make a New Englander think he is in Florida in the dead of winter.

it puts out an initial 16,000 lumens. but the light fades very quickly. the good news is that there's no heat generated from the bulbs, so they can be close to the plants. I recommend about 2-3 inches away (no further) from the foliage. I will also add that I was skeptical about fluorescent lighting systems entirely, until it tried these. I am impressed. just keep them close to the plants. (-:

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

Short answer much as a 400 watt ballastThere are also different bulbs for different applications all with different spectrums/lumen outputs it keeps nodes shorter (doesn't reach from heat stress) bulbs average 1600 lumens per

The info. I got was 500. I have no way of testing it. At 500 or 600 its still super bright. I saw a test where it beat a 800 lumen light.

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 claims to be 1,000 lumens but I seriously doubt that. My guess it is closer to 200 but it is VERY bright and a good deal for the price.

42 Lumens. Its quite bright. Meaning, don't stare directly into it (unless you enjoy going blind) - kind of like the sun except smaller. Technology is amazing, this includes the internet.. love your work Mr. Draper.

I'm not sure of the actual lumens, but it can be adjusted down to a subtle, warm glow. Hope that helps.

Don't know lumens. If I had to guess, equivalent of about a 25 watt incandescent. It casts a light in about a 10' radius and bright enough to open a combo lock on a shed.

The number of lumens would depend on the size of the bulb, I am not sure what it puts out. I will say it is not as bright as the old incandescent bulb, but it works ok. We have an additional stip lighting under the awning frame that we use when working outside, we only use the StarLight SL when we are away and return to the camper. Sorry I couldn't be of more help.

I don't really know the science. The description I read says 25 lumens, 10 LED bulbs, so perhaps this means 10x25=250 lumens? The unit puts out about what I'd expect from a small flashlight.

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

Don't Know The Lumen Count, For A 3 AAA Powered Light Its The Best I've Had, the Battery Life Is TheTrade , Worth It In My Opinion

I don't know the output in lumens, but for my model the color is daylight or cool white, not warm white like and incandescent. Possibly you can specify a color temperature?

It may say it puts out 16,000 lumens but the determining factors of how much your plants receive depends how close the light is them... Initial output is 16,000 from the bulb. I do recomend replaceing every 9 months because like all lights these lose thier briteness

I don't know number of lumen but my flashlight stopped working after a few months. As their promise " lifefetime warra ty", they are very responsive and concern immediately sent me a new one. I am very please and satisfied.Saeree J.

It's 230 lumens. I have to tell you, these nightsticks are great. I have three, and rotate through them as they need to be charged. They've got two magnets, and can fit almost anywhere in, under or around a car. I use mine all the time. Don't hesitate to buy.

The lumen output goes up very slightly as voltage rises due to the regulation not being perfect, but the difference is so small that most peoples' eyes could not discern the difference. Lumen output is roughly 1200 to 1500 lumens, it is hard to compare since the beam is so floody but this is what the component datasheet suggests at the measured drive current.

I cannot answer in Lumens but I can tell you this light is not nearly as bright as any of my other LED flashlights. I am disappointed by it every time I use it.
