The advantages of True-Light:

  • True-Light lights are virtually identical to the spectrum of natural daylight ( CRI 96/ colour temperature 5500 K).
  • True-Light lamps contribute to the well-being of humans and animals by spreading UVA and UVB.
  • True-Light lamps stimulate the immune system.
  • True-Light activates the synthesis of vitamin D, which is necessary for the absorption of calcium and other minerals in the blood.
  • True-Light helps you with your winter blues.

True-Light full spectrum daylight lamps are fluorescent - and LED lamps. They were  designed in the United States for NASA to simulate daylight for astronauts and crew of submarines.


You will find a number of terms which are perhaps unknown when you inform yourself about natural daylight. A number of these terms are briefly explained below.
