Question: I need a light to read sheet music or 81/2x11 inch lyric sheets when playing an organ or keyboard with book stand.  Is this lamp suitable?
Document: Good quality as advertised. Excellent sheet music light for my piano. Bright and easily adjustable light. I would recommend this light.
Designed well, gives a bright  direct, light; peace of mind in case of black-out.I put it on top of my piano, a perfect lighting for sheet music and good-looking enough to  display. Five stars.
Not tall enough to reach over sheet music. Barely bright enough to light a page of music. Attractive, bendable, easy to use.
Excellent lamp suitable for many uses. We purchased two for hurricane emergencies where electric power is lost, but they are handy wherever you need a no-hands light.
The lamp is lightweight yet sturdy.The neck flexes easily and seems like it will be very workable for a long time. The light is very nice and bright, easy to read by in the dark. The three AA batteries pop in easily. I don't know how long they will last because I haven't used it enough yet. Easy to take for use in a dark closet, tent, porch, car or anywhere you need it. Delovery was quick and lamp was well packed.
I like the size of this lamp, and I am intrigued that other reviewers say the bulbs never need replaced. I wish it was a little brighter, but I use it to read at night in bed, so it really is fine for my needs.
My husband used this in his home office to light up his keyboard and read materials that he wanted to respond to and it was so weak that it was useless. He left the light on and it faded out so much that you forgot it was on. We changed the batteries and it didn't improve at all. We were very disappointed.
This L.E.D. light is great... It is vary well made and the light quality is much better than the Colman L.E.D. Latern I used to use when the power went out. Because you can angle the light head however you want, you can easily read a book. Not so with the Colman... That sucker beamed rite in my eyes when I tried to read. You will like this lite.
This lamp is perfect for my music studio, but it's brightness fades rapidly. I use rechargeable batteries but I find I have to change them every 3 days to keep the light working brightly, which is a little inconvenient. Definitely get rechargeable batteries if you are considering this purchase.
The title says it all! The LED lights on here are really bright so you can read it the total darkness with no problem. It's small and takes up very little space and it runs on batteries so you don't need to be hunting around for an outlet or running cords all over the place. I use mine alot and take it camping and it broke so I had to get another. I'd really like it if was made out of some super duper hard plastic like a Glock so it could take more abuse.
Answer: yes
