This light, as promoted by Dr Oz and Shark Tank and a host of physicians battling SAD (seasonal affective disorder), is advertised as full spectrum but the companies that make the 10,000 Lux light bulb admit it does not emit UV light. This means it's not actually full spectrum. So how do they get away with calling it full spectrum? One company, which has the gall to call itself Circadian Optics, explains that the bulb does not contain "unwanted" UV light.
So if it's unwanted it's not actually part of the light spectrum; right?
Then some wonder why I titled this series "What use is it to reason with sleepwalkers?" We're at Part 3 by the way.
As to those who rave in the Amazon comment section about how the bulb wakes them up, of course you're going to feel woke -- dare I use the term -- if you have a 10,000 Lux light shining on your face but this does virtually nothing to rev up the body's factory when it receives full-spectrum light. So important is full spectrum light to the human organism that it can be considered the master key to mental and physical health and the energy we need for the workday.
There is one company I know about that sells a full spectrum wake-up light bulb, which is nicknamed Joyous Light. That it is. It's a wonderful invention.
As advertised at Amazon:
ALZO 15W Joyous Light Full Spectrum CFL Light Bulb 5500K, 750 Lumens, 120V, Pack of 4, Daylight White Light.
I suspect that the most the 10,000 Lux competitors can say against the Joyous Light it is to insert complaints about quality control at Amazon's comment section (My box of lights arrived crushed. The lights didn't work I want a refund. Etc.) My box didn't arrive crushed and the light bulbs work fine. I use one in the kitchen in a table lamp with the lamp shade removed and with the overhead fluorescent on; the effect is a room flooded with gentle sunlight. (There are larger size Joyous Lights for sale but the small one works fine for my purposes.)
The bulb isn't a complete substitute for at least two hours of early-morning sunlight but it is a godsend for people who can't manage to get outside in the morning for that long. So at $23 for a box of four, it's the best investment that sunlight-deprived people can make.
Oh wait, I see it's currently unavailable at Amazon; I hope that means it's sold out there. Well, you can order directly from the company.
