These NBA are interesting for this specific use.But CRI would be very low.
Where we can get on 3535 - 5050 size?
Rat poison?
What have you been smoking?
Don't tell me you've been smoking colloidal silver again. 
Article that was linked indicates “each participant had an average of 38.4 hours over this period” thus your “Phone hours/ total patients = Average” wouldn’t be the equation that would apply as that would be the average of the observed group, BUT okay lets say it does, the way they presented the information is very deceiving as its the sum total time on the phone during the 30 day observation period of the group not a real average of each participant as indicated.
With this information that would roughly amount to an hour and 20~ minutes daily BUT they also indicated it averaged out to be around 3.7 mins per hour during the day on a say a 16 hour day that would only be 59 minutes on the daily. The average person generally spends more time on a computer for work, watching tv in leisure etc than whats indicated in this article…. One would think the volume of time in front of a monitor or tv is more detrimental than 1~ hour on your phone periodically through out the day…
The Galaxy Note 9,has the same capability as well.
I think that halogen lights emit large quantities of blue light.
Right up into the UV, too.
I still got one of those leak-detecting kits with UV dyes that you can add to oil, coolant, etc. Instead of a UVLED light, there’s a “gun” with 50W halogen bulb behind a silvered-glass filter. Blocks all VIS light and leaves only UV, like a ZWB2 filter.
Of course, I’d use one of my lights vs that beast, but…
this has nothing to do with CRI
you can get red in 660 and 730nm, plus green 520nm and
Amber 595nm all from kaidomain.
and people, please dont reply to the Blue Light Deniers, they are just hijacking the discussion to talk about splenda… dont take the bait.
These 595nm are phosphor converted or native amber emitters as I need?
they look native to me,
you should contact the seller directly with your questions
Do read the nurses study links, that was quite well done research.
OK, cool. Thanks for letting me know.
Hi everyone, thanks for the efforts made thus far to avoid controversies and arguments in this thread. But it does feel like it’s going to start getting ugly. Please try to avoid the more controversial aspects of this topic, and don’t dig in your heels if somebody expresses a different viewpoint. Thanks in advance!
No word from me about the direct correlation of blue light = disease.
Otherwise we shouldn’t even expose or watch sunlight 
But I have personal experience that cool/white lights can affect the sleep cycle more. And that it’s important for regenerate organism and endocrine system.
Remember when in my street replaced HPS bulb for white Leds.
Plus the introduction of cool white headlights on cars/bikes in the opposite lane, how much longer it took me to fall sleep than before. Same sensation of ‘’wake up’’ when I watched from afar 5000k Metal Halide instead the almost irrelevant Orange HPS Bulb at similar power.
And not good also watch TV,Phone etc… before sleep,maybe I’m sensitive.
Yes, I too think it’s about artificial light at night and breaking the natural cycle. Pure luck there are wavelengths not influencing release of melatonin.
What I don’t understand: Green is supposed to supress melatonin, right? When we watch yellow light, both red and green receptors are stimulated (else we wouldn’t see yellow), so the effect has nothing to do with receptors, or am I wrong somewhere?
Oh LoL true,like traffic lights.
The Red made relax then Green wake up to restart you on car.
Anyway can’ t reply to your question sorry!
melatonin friendly colors, happen to be the colors of fire 
so are you asking if Yellow light suppresses melatonin? I think yes.
I’ve read it doesn’t but I wouldn’t wonder if I mixed something up again.
That’s why there is boom of melatonin integrator sale
The people you working with were most likely so tired they probably near the verge of falling asleep on shift. As others have mentioned, if you’re so tired, you can easily fall asleep in the middle of the day.
Here’s more evidence from U.C. Davis
“Continued exposure to blue light over time could damage retinal cells and cause vision problems such as age-related macular degeneration. It can also contribute to cataracts, eye cancer and growths on the clear covering over the white part of the eye…Exposure to blue light before bedtime also can disrupt sleep patterns because it affects when our bodies create melatonin.”
And more from U.C. San Francisco. This is the research the dailymail used, so it isn’t the daily mail saying this. Although their reporting may be a bit sloppy; the meat of the issue and research is still there.
“Smartphone use directly correlates with sleep, with greater use demonstrating a significant association with shorter sleep duration and worse sleep efficiency, according to researchers at UC San Francisco…This was the first study to examine such use in a broad population, directly measuring screen time rather than relying on self-reported use. And, those with more screen time use had poorer sleep…”
Galaxy Note 9,has a filter to minimize blue light.
