Review of daylight lamps versus full spectrum lamps
In reviewing the differences of daylight lamps and Full Spectrum lamps we need to start with the specifics of the sun.
NATURAL SUNSHINE measured
Natural sunshine measured over Germany on a clear sky at noontime in July 2005 showed the following characteristics:
1. Full spectrum including UV-A, UV-B and UV-C
2. CRI (colour rendering index) 99
3. Colour temperature 5850 Kelvin
DAYLIGHT LAMPS requirements
All daylight lamps, also the tri-phosphor conventional lamps having a colour temperature in the range of 5500 Kelvin up to 6500 Kelvin are daylight lamps.
These lamps may have a CRI (colour rendering index) of lower than 90 and no full spectrum.
FULL SPECTRUM DAYLIGHT FLUORESCENT LAMPS
Full spectrum daylight fluorescent lamps as documented in the book of Dr. Jacob Liberman, O.D., Ph.D.
“Light Medicine of the future” have the following characteristics:
1. Full spectrum of light including the UV
2. CRI (colour rendering index) of 90 or higher
3. Colour temperature in the range of 5500 Kelvin up to 6500 Kelvin
NEOSAVE FULL SPECTRUM DAYLIGHT LAMPS
Neosave full spectrum daylight lamps have the following characteristics:
1. Full spectrum of light including UV-A und UV-B (no UV-C)
2. CRI (colour rendering index) 96
3. Colour temperature 5800 Kelvin
