Sorry if i'm repeating someone, but I would not run any 730nm with your whites during the day. You have enough 730nm already! Only use it as a lights out signal.
Oh... unless you like STRETCH. hahaha (the stretch is how you know it's real science!)

How does the Philips Wake-up Light work?
The light gradually increases from soft dawn reds through warm orange to bright yellow light 30 minutes before your set alarm time.
This signals your body to move from sleep to waking, for a natural wake-up light experience. At your chosen time, a natural sound starts playing to make sure you are awake
Light sensitivity is different for everyone. In general, when using a higher light intensity we need less time to fully wake up.
There are 20 light intensities to choose from with the Wake-up Light, so you can fully adjust the intensity to suit your needs. You can also add natural sounds, radio, or your favorite song from your iPhone library (only for HF3550). Wake up just the way you want.

Blue or white light therapy?
The Philips EnergyLight and the Philips goLITE BLU light therapy products both help equally well to fight the winter blues.
Many people love the 10.000 lux white EnergyLight. It’s been used in traditional light therapy for more than 25 years, bringing a touch of natural daylight into your home.
Others prefer the compact and portable goLITE BLU with the light from the blue summer sky. Scientific research of the past 10 years has shown that this color of light (while also contained in white light) is essential for effective energy lights.
Safety
Philips energy lights are medical devices. They comply to Medical Device Directive: 2007/47/EC, MDD 93/42/EEC and all the safety standards required.

Thank you so much for making such an excellent product. It sits right on my desk at work, where I can use it without any trouble during my workday. I can tell I am sleeping better and feel far less exhausted in the evenings. We've had a very gray winter and this has completely snapped me out of the doldrums. Thanks again.
Jeannie Locatelli
The winter 'veil' lifted the first time I used it. My energy level has improved and my appetite has gone away. I have no cravings at all. I need to be careful not to use it after 5:00 p.m. I use it once in the morning for 15 minutes and once in the afternoon for 15 -20 minutes.
Erica Skyrman
Love the portability. I've been able to take it out of the house and show it to 3 friends.

Very easy to use and the results from using the device are impressive even after a short time.

Althought for human use intended ..
I guess we're not so 'far' different as living organisms ,afterall... )
Anyway ..Does anybody know a way ,for me to upload a new spreadsheet ,I'm preparing ?
I think some of you might like it ...

News & Info
The launch of the Decor Series Class A arrays marks Bridgelux's new "human-centric" approach to product development and color targeting by using Gamut Area Index (GAI) to measure how light and color appeal to and are perceived by the human brain.
Available through global channels in mid-November, the new Decor Series Class A arrays are the first products to use the full Class A Color specification from the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute and the Alliance for Solid-State Illumination Systems and Technologies (ASSIST).
In research and development since 2002, Class A Color was created at the LRC with funding by ASSIST. Class A Color redefines high color quality of light. The long-term study examined how people perceive white light sources and what they prefer in terms of color rendering and the white hue or tint of a light source. Bridgelux specifiers and engineers developed prototype lamps based on the Class A Color spectral requirements for the LRC to use in field evaluations.
"Class A Color has been broadly tested and 'tuned' to ensure the most pleasing blend of naturalness and vividness based on subjective human perceptions," said Jean Paul Freyssinier, senior research scientist at the Lighting Research Center. "A majority (75 percent) of those tested from around the world agree that Class A Color light sources provide the best color rendering and optimum saturation levels. It's consistent lighting that won't disappoint."
Distinguished by its human appeal, brightness and natural rendering, Class A colors are inherently more vivid and whites are their whitest due to a broader spectrum of colors and saturation. By achieving a balance of color properties that match how people perceive color, the Bridgelux Decor Series Class A LED arrays not only deliver superior color quality, but provide a better return on investment when compared to traditional halogen and ceramic metal halide bulbs.
Decor Series Class A LEDs consume 30 percent less energy, generate 70 percent less heat, and last 20 times longer than halogen or metal halide light sources.
Lighting has become a critical design feature for high-end retail and commercial spaces, with solid-state LED technologies playing a vital role in helping businesses differentiate and stand out to their customers. Whether creating ambience in a luxury hotel lobby, showcasing merchandise in a retail store or illuminating museum works of art, Decor Series Class A LED arrays deliver a stunning visual experience by appealing to people's natural perception of light, helping to drive improved aesthetics, increased visits, customer purchases and revenue per square foot.
"The launch of our Decor Series Class A LED arrays is a game changer for Bridgelux, our customers and the industry," said Brad Bullington, CEO of Bridgelux. "Light has the power to influence how people behave, what they purchase, their productivity and their mood. Our new human-centric approach harnesses that potential to help our customers create custom light experiences that deliver great aesthetics and a tangible financial impact."
Traditionally, the lighting industry uses Color Rendering Index (CRI) as a primary measure of light quality; however, CRI only measures color distortion. Gamut Area Index (GAI) measures color saturation and strength to more accurately reflect the holistic effect of light and how a person will perceive color. Bridgelux Decor Series Class A is engineered at the optimal GAI and CRI combination based on human perception of light.
Bridgelux Vero Decor Series Class A arrays will be available in 4000 K and 3000 K CCT. They're designed for applications including high-end retail, hospitality, museums and commercial spaces.

What supposedly happens after 10minutes of far red exposure? My plant isn't gonna uproot itself in the middle of the night and roll me into a six foot long joint and smoke me is she?! Because I once saw that in a movie ..

(not fully functional yet .)
Cheers.
Have to go and get some sleep ...
PS :
4 x 3000K 80 ABs & 2x 3000K 93-95 cri Y2s ..
all six at 1400mA ...
Overall led array efficiency ~39% ...(39,1 % )
Not bad ....
