I’d love it if you could find a way to support shutting off all the blue light emission from your lighting products. Soraa is doing some interesting things here but it seems they’re going the “pro” route and discontinuing their “home” product line. I haven’t tried them personally, but I’m building a new house and my ideal setup/plan is your switches, Home Assistant for central smart home control, and non-existant smart lights where I could turn off all the blue light emission in the evening.
I assume you’re talking about the LED bar on the switches and dimmers? (They obviously have no control over what the lights on the load they are attached to does in this regard.) If so, if it’s of any help, you can completely disable the LED bar (definitely one way to get rid of blue light), adjust its brightness up/down, or change its color (though I’m not sure what component LEDs/colors it uses to make the arbitrary hues you can make it generate…though especially on the switches I can’t imagine this could be much either way).
These can all be done via Z-Wave parameters. You could easily make Home Assistant or whatever hub/software you end up using (assuming it’s not a super-limited platform like Wink) do any of these things based on whatever criteria you want, including time.
Nope, I’m talking about how research has found that exposure to blue light suppresses the production of the sleep hormone melatonin more than any other type of light. So no, not just the little status LED’s I’m suggesting a pretty large engineering endeavor to support turning off the blue light emission from any of the LED based lighting products.
What engineering endeavor are you asking for? Inovelli has 5 products, 4 light switches and 1 RGBW bulb. I’m pretty sure the bulb is a white label product meaning another company created it and Inovelli slapped their name on it possibly with a custom z-wave firmware or device handlers. So when you say “support shutting off all the blue light emission from your lighting products”, with what lighting products are you referring to?
I suppose future LED bulbs or strips. Also, making sure the switches could handle and communicate that kind of command to the lights. Maybe they could work with a partner like Sorea then on smart lighting (I don’t think Sorea does smart products today)? Hey, this section is for wishlist items and suggestions right?
That makes sense. I was confused since the only products that Inovelli fully engineered are their new line of switches, I believe every other product available has been a white label product. I had never heard of Soraa until you posted about them. I would be curious to know if they left the consumer space because it just wasn’t profitable for them? I only found one a19 bulb for sale and it was listed at $14. Either way it’s a solid suggestion and thanks for explaining.
Yes, indeed, because it allows for suggestions to be discussed. While composing this messaged, I had believed @flipontheradio was merely suggesting that this isn’t something that could be done, as such a feature would need to be some sort of standard that was embedded into the lights in everyone’s homes.
A quick Google search suggests there are LED bulbs claiming to have lower blue light.
As I am in a new home with many dedicated LED fixtures, what I do is have automation bring on lights at much lower brightness at nighttime, when it’s getting closer to bedtime. This is helpful whether or not you believe blue light spectrum is an issue.
As for that article, Wikipedia has a few interesting notes:
Current academic and medical consensus suggests there are no known health effects of day-to-day exposure to blue light (visible light with wavelengths 400-450 nm), and it is not regarded as a cause of eye disease or eye strain, as distinct from any other frequency band of visible light. Despite the lack of scientific basis, numerous products and software claim to filter out blue light to prevent eye strain and sleep disruptions. Research into this area is often inconsistently reported. It is unlawful in the UK for a health practitioner to indicate to a patient that 400-450 nm blue light causes negative health effects or alters sleep. Harvard Health continues to support claims that exposure to blue light at night has a stronger negative effect on sleep.
Under Aggressive Marketing heading…
Harvard University suggests - without revealing its original research or having any listed authors, suggesting a paid advertisement and not a scholarly reference - that blue light adversely affects the circadian rhythm. They appear to have partially attempted to retract their previous health claims from 2012, “Light at night is bad for your health, and exposure to blue light emitted by electronics and energy-efficient lightbulbs may be especially so.” The main article is not supported by any references or authorship but states that blue light could “potentially cause disease”.]
Thankyou @LongDono, good add to the conversation. I admit that I’d just accepted this as proven science. It’s a bit not super easy to find peer-reviewed proof (granted I didn’t check who funded it that’s recent, but after searching through some published research )… but it does seem pretty well established that blue light during the day helps you feel more awake, and blue light at night makes it harder to sleep.
Here’s some stuff I found interesting:
