It's a
L A S E R
which stands for
Light Amplification by Stimulated Emission of Radiation

But you're right, LEDs are not lasers. Although there are LED lasers out there.
turtle420 Reviewed by turtle420 on . Laser Lighting Just a little experiment... I have one of those laser key chains on my key for under the house now... I'm wondering if a little of that red color spectrum will help a leaf or burn it? Would a small amount of time on the plants help or hurt... I'll experiment with a leaf first. Rating: 5
