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. This is more than lighting.
See this Melatonin lab test by Mark S. Rea, PhD
and see the 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.
