LED keychains are not lazers. With a lazer, the light is "lazed". It is one wave length and is emmitted in a straight line of light (a beam of light). LED's are not "lazed" and the light emitted spreads out instead of staying as one concentrated beam.
frosty1 Reviewed by frosty1 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
