ConstantColor® CMH® provides a
consistent “white look”, which is
critical for interior applications.
Long life
2 – 3 times longer life than
Incandescent or Halogen PAR lamps.
Highly efficient
4 times more lumens per watt than
Incandescent or Halogen PARs.
Excellent color rendering
Warm white light (3000K) and
exceptional color rendering (>80 CRI)
make ConstantColor® CMH® an
ideal source for indoor applications.
