True-Light: 50 years of original daylight lamps.

For prices in the United Kingdom & Ireland: or

These full spectrum daylight lamps were developed for NASA in the United Stated in the 1960s. Astronauts and submarine crew experienced complaints due to lack of daylight, the answer was found in the use of True-Light full spectrum daylight!

True-Light almost equals daylight, it has a CRI of 96! Regular daylight lamps do not have the essential parts of the spectral range and therefore miss the positive effects of natural daylight: stimulation of vitamin D production, a healthy work- and living environment and a perfect colour reflection. Besides, True-Light is made of a sodium glass tube, which allows healthy UV A and UV B to shine through.

Product information, applications and references will give you a clear idea of what True-Light stands for: first rate quality lighting! Scientific research and users’ experiences show True-Light is just as healthy to humans, animals and plants as natural daylight. That is why True-Light is suitable for all sectors.

Product properties

Even though nature cannot be improved, we can strive to copy its perfection. That is exactly what True-Light does. Made from the finest materials; 14 (!) different natural phosphor powders and pure argon gas combined with a UV transmitting sodium glass, make True- Light is a product of the highest quality.

Colour rendition

The colour temperature is 5500 Kelvin.

The Colour Rendering Index of True-Light is 96, taking into account that natural daylight is 100. Compare this to the Colour Rendering Index of an ordinary Cool White bulb, which is only 68!


Colour brightness

In contrast to other artificial lights, which transmit light within the yellow band, True Light emits natural daylight throughout the lamp. The result? Better sight, less stress, no fatigue being active and feeling healthy. True-Light transmits an optimum brightness of the light and a perfect colour rendition.


True-Light cannot be compared to other daylight lamps, True-Light is the original! Due to the UV transmitting sodium glass and the fourteen different phosphors, True-Light almost equals natural daylight more than any other daylight lamps.

True-Light: often imitated, never equalled!
