Longwave Ultraviolet LED Light
$ 20.00 each (plus
shipping & handling)
This small key chain LED Light is very powerful for
its size! It has a narrow beam that is just outside the visible
spectrum (.370 um). In full darkness it will cause objects to
fluoresce at distances of 20 feet or more. In lit conditions it
will still be visible when used at about 6 to 12 inches.
NOTE: This
keychain light does not have the (purple light) that comes through
on the $5 keychain.. so you are able to see more fluorescence.
WARNING:
Never look directly at the beam! UV light will cause eye damage!
