Lux24™

LIGHT FOR A BETTER NIGHT'S SLEEP

Having Trouble Falling Asleep?

Exposure to light rich in blue wavelengths during evening hours can be detrimental to sleep quality.1 Blue light is not only coming from smartphones, computer screens and tablets - it's also abundant in regular light bulbs.

Lux24™ LED bulbs are designed at the spectral level to limit disruption to restful sleep by utilizing a proprietary blend of long wavelength phosphors, which limit the amount of blue light.

Blue Light and Melatonin

Blue light is known to suppress the production of melatonin2, a hormone that promotes sleepiness.

With a special focus on reducing the amount of blue-rich wavelengths, Lux24™ Circadian LED bulbs allow for the body's natural production of melatonin.

A Spectral Look At Lux24™

Energy-saving LED bulbs attempt to mimic the look and the "warm" color of an incandescent bulb, but a closer look at the light spectrum reveals that there is a significant amount of blue wavelength content.

Taking a closer look at the spectral power distribution of these light sources reveals a significant amount of blue-rich wavelengths between 450 and 510 nm, which is also the peak sensitivity wavelengths for melanopsin, a pigment in our eyes that triggers the suppression of melatonin.

Measuring and Comparing M/P Ratios

A light source's melanopic to photopic lux ratio (M/P ratio) gives us a useful way to directly compare the effect of multiple light sources on melanopsin response.

The M/P ratio represents the impact on melanopsin response (melanopic lux) compared to the amount of perceived brightness (photopic lux). A lower ratio indicates a lesser impact on melanopsin suppression for a given amount of brightness.

Lux24™ LED bulbs have a M/P ratio of 0.39. What this means is that for every 100 lux, only 39 "melanopic" lux are emitted.

Soft and Comfortable Light

Lux24 Circadian LED Bulbs provide soft and warm light, perfect for reading and other evening activities. Brightness is equivalent to a 40W incandescent bulb. Colors appear vibrant and natural.
