What's the light output? This is usually measured in a unit called lumens, and MightyBright claims their 'orchestra light' is 100 lumens

Neither the package nor the light itself have any marking for lumens, but it is plenty bright. The nine LEDs are spread over a distance of 6.25 inches and are more than adequate for lighting 2 pages of music in a relatively dark environment. That said, I do not recommend this light. The seller is shipping different lights to different buyers. What I got has different features than some of the reviewers are describing. My light is not rechargeable (unless you provide your own rechargeable batteries and external charger). Also the battery circuit stopped working after six months. Now the light only works from the AC adapter which came with a measly 3' foot cord. Neither the package nor the light itself have any marking for lumens, but it is plenty bright.

I'm not sure of the actual numbers, but when it's charged, it's great! I use it every week,we play for 3 hours straight, and I will occasionally forget to charge it, and it's good to go the next week!

The unit or package insert do not say what the lumens are; I am not certain if LEDs are measured in lumens or not. There are two settings...one for high and one for low. I find that the high is very bright and sufficient to cover two - four pages of music. I've tried other portable music lights, but I really like this one. Hope this is helpful.

This unit is 700 Lumens. I am blown away by the quality for the price I paid for this unit. The features and included accessories are amazing!

This unit is rated @ 120Vac, 60Hz, and a Max 6.5 Watts. NOTE: This unit produces 300 Lumens. You can't convert directly between Lumens and Watts. They are measuring completely different things. Lumens measure the flux of a light being produced by a light source or received by a surface. Watts measure the amount of power used (P=EI).

It's pretty bright during the day. Other's have said that this outshines most of the other lights. I don't know what lumens it produces, though

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).

I don't know the lumens. It is more than bright enough to light up the interior of a large cabinet. We have had it over one hear and have not yet replaced the original batteries. It's a good unit.

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).

I'm not sure on the lumens, but it has 10 LED lights. It works terrific on my sewing machine (I attached it with Velcro) and the lights don't dim at all because it is electric. It works great for what I need it to do.

I don't know what the exact lumen output is, but our basil plant did really well under its light at about 6 to 8 inches away while the glow panel was new. Unfortunately, the life time of this device is not good. The LEDs, especially the blue ones go dim or die outright in less than a year at a usage of about 10 hours a day. After enough LEDs fail, the whole rest of the array no longer lights up at all. I would rate this grow lamp much higher, if the LEDs were individually user replaceable and purchasable at a reasonable price each.

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.

To the best of my knowledge, the brightness levels of this wonderful pocket light are 260 and 13 Lumens (high and low). I've had mine a couple years now....always on my belt!

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.

Dennis, Lumins is the total amount of light generated by a light source .. Lux is the Brightness of illumination on a surface at a given distance. This is a Lux meter. Measuring Lumins is much more sophisticated and generally beyond the needs of most folks. Google "Integrating Sphere" for some Lumin info. Cheers!

I don't have actual lumens, but I can tell you for a fact that it is BRIGHT. I typically keep it on the low setting. What is especially nice is the wide angle of illumination; You can open up several pages of sheet music and it covers them all. The only thing some people may not light is the color temperature. It is a clear white light, without the amber hues of tungsten.

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

1800 lumens is just enough to light up a specific area. You can use it in your room when you're working. It's really bright. I've had the original bulb replaced with this one and it's brighter for me Triangle Bulbs T50026 - FML27/65K, 27 Watt, 6500K Natural Daylight, 4-pin GX10q-4 Base, FML Compact Fluorescent Light Bulb

I don't have a way to measure lumens. This light casts a wide beam with spot light in center. I would estimate between 400-500 lumens on high setting. For cost and how long batteries last. Light is well worth asking price.
