In some ways LEDs help, and in some they may harm.
|Timing Example -
Before the ′50s our United States experienced atmospheric LEAD poisoning.
It was defended by
Auto and Petrol suppliers against Geochemist Clair Patterson, PhD.
After 20 years, Government took his advice.
|- - Now - -
This relates our environment and the 450nm emission of white light,
and is more than lighting.
See: Melatonin lab test by Mark S. Rea, PhD
& Circadian Effects caused by these LED types
This ⇒cool-white LED
reduces melatonin twice as much as reduced by this ⇒warm-white LED.
Why? Intrinsically-Photosensitive Retinal Ganglion Cells (ipRGCs)
respond to LED′s blue light spike.
These ⇒cool-white LEDs
have 2× 450nm as their 500-700nm, a color ratio
exceeding natural light.
These ⇒white LEDs
show 450nm blue emission less than half their 500-700nm emissions.
Atmosphere protects us from
We need awareness of ′blue per Lux′ with all lighting.
If you′re in cool-white lighting near bedtime, then
estimate a sleep aid supplement for proper rest.
|| Nocturnal Melatonin Suppression = endocrine disruptor linked to
diabetes, obesity and cancer
Fluorescent lighting has done this for decades,
and LEDs could prevent this problem if desired.
Health issues are rising every year: we are not sleeping well
& we need more sleeping aids.
How long did it take to get health warnings on cigarettes, or on gasoline pumps?
Answer: 20+ years
We will see warning labels for cool-white LEDs.
