Large 450mm diameter, ultra-thin source panel with tripod included.

Blend sky blue 480nm and 850nm near-infrared LEDs in any ratio you want.

On max brightness, melanopic lux at same distance as 10k lux claims estimated as equivalent to ~60,000 lux white LED without being as bright or harsh since there is no green or dark blue.

The ultimate tool for circadian rhythms and photobiomodulation-driven cognitive enhancement.

This is not a SAD light. This is a portal connecting the interior of a building to a natural outdoor setting.

Nearly half as much near-infrared power as the IRONFORGE Green Series.

How much near-IR can you get with the Sky Portal at your desk?

The Sky Portal has 40% the near-infrared output of the IRONFORGE Green Series. Since the angle of the output light is 80 degrees, we can consider the center column, plus two triangles on either side with 40 degree angles off of straight.

To find the additional triangle contribution to the diameter of our circle, we solve for Opposite in Tangent(40 degrees) = Opposite/Adjacent. The Adjacent is the distance your head is from the light and we will take that to be 1m so all we need to do is Tan(40deg) times 1 = 0.84. We have 2 triangles, plus the 0.45m circle so our projected light diameter is 2.13m, giving us an area of 3.56m^2.

 

The head has a 56 cm circumference, giving us a 250cm^2 cross-sectional area, which takes up 0.7% of the light being given off. The upper torso might capture around 3.5%. This equates to 357x less than Green Series on head, and 71x less than Green Series on upper torso.

But we can easily be sitting under this light for a while. Let's say 8 hours at a desk. This gets us 1.34 minute equivalent of Green Series just on head + 6.76 minute equivalent of Green Series just on upper torso. Not bad.

If you can position the Sky Portal just 0.5m from your head with one of those angle 2-piece tripods, you can 2.7x these numbers!

This of course trounces the VieLights, anti-baldness caps, and beauty face masks that you'd only use ~10 minutes at a time.
