Comfort

COMFORT

We've incorporated several important features into our light boxes designed to increase user comfort. These include a downward angle, using full spectrum light, and high quality electronic ballasts.

Downward Angle The downward angle that researchers recommend for increasing light delivery to the eye and improving efficacy also increases user comfort. Rather than shining the light into your eyes from an upright position, much like the lights of oncoming headlights when you're driving at night, the tilted angle allows the light to enter indirectly through your peripheral vision. This does not in any way diminish the light reaching your retina; rather, it spreads it over a larger part of your eye. This reduces the apparent brightness of the unit, decreases glare, and makes it much more comfortable to use.Several SunBox designs incorporate this feature into their design.

Full Spectrum Light

The term "full spectrum" is a loosely defined term in the lighting industry. Generally, it refers to light that has a color temperature of between 5,000-6,500° Kelvin. It may, but does not necessarily, include the UV wavelengths - again, the term is loosely defined, and is used differently by different lighting companies. At The SunBox Company, we use the term to mean the visible portion of the spectrum, without the UV wavelengths.

Full spectrum light, regardless of whether it contains UV, appears whiter than other types of artificial light - cool white, warm white, broad spectrum - as it contains a greater distribution of colors within the visible spectrum (White light is composed of all the different colors of the spectrum). Cool white bulbs, for example, appear yellow-orange when compared with full spectrum bulbs, because they are significantly deficient in the blue-green part of the spectrum.

All SunBox light boxes use bulbs that emit color temperatures of 5,000-5,500° Kelvin. As stated in the Safety section above, we eliminate the UV wavelengths from our light boxes with the acrylic diffuser.

High Quality Electronic Ballasts

We're all familiar with the distinct hum and the annoying flicker of fluorescent fixtures. Generally, fixtures that emit this hum and that flicker have older, magnetic ballasts. Higher quality electronic ballasts, such as the ones that have been standard in all SunBox light boxes for several years, reduce the hum and the flicker associated with fluorescent fixtures.
