What about UV light causing skin cancer?
A: Their are three classes of UV light. A,
B and C.
B and C are the shortest wavelengths. B and
C are considered germicidal and the ones responsible for skin damage. UVLed's
emit class A light at the edge of visible light, causing little damage. UVLed's
have low level light output, nothing like the sun's intensity.
So add a little bit of sunshine to areas
that normally are in the dark, the dark areas where fungus thrive!
Will over exposure be harmful?
A:Yes, over exposure to UVA is harmful, burns
are the result. Like a bad sunburn, maybe some peeling or even blisters. Be
I harm my eyes looking directly at UVLed's?
Never look directly at the LED's without
eye protection - not even for a minute. Symptoms of UV exposure may not appear
immediately; they can be delayed by 30 minutes to several hours. They can
include a burning or "sand in the eyes" sensation, and a hazy look around
light bulbs and other bright objects. Mild cases are self-correcting within
24 to 36 hours; however if despite my warnings you still stared at the LED
from close range for more than a few minutes, it might not be a bad idea to
see an eye doctor and tell him you've been exposed to UVA radiation. DISCLAIMER:
