Reasonable replacement for a piano lamp
It came and it worked, but in a piano lamp one has to be careful to keep the lamp shade rotated such that the LED's aren't in direct view. That's because this lamp is thicker (about 1.75") than the T-10 sausage-shaped incandescent it replaces. Aside from that, it's nice and bright, and my piano teacher seems to like it.
