This is a sturdy and good quality lamp.
You can use it plugged in with a cord or with just batteries.
Be aware that if you use batteries the light will slowly dim down long before the batteries are dead.
I would prefer a sudden “death” of light instead of the gradual fade out as the light soon gets too weak for me.
I therefore use it plugged in all the time for maximum light.
It’s a small hassle as you have to be careful not to stumble in the cord, it limits where you can practice since you must sit near a power outlet, and, since I have a robot vacuum cleaner, I have to remove the cord after every practice so the robot doesn’t get entangled.
I have a music stand with a solid K&M walnut plate and it is very easy to fasten and relocate the lamp to the plate with the attachment clip.
The plate is also tall enough for the sheet music to go clear of the clip.
The clip will also stay secured on the more common metal mobile music stands that most kids use. But be aware that since they are fairly light and unstable you get an added weight on top that will further increase the instability of the music stand.
You will also only be able to have two music sheets on the stand at a time since the mid section will be occupied by the lamp clip.
All in all I am very happy with the lamp.
