Spectral Distribution (Measured)

  • The Philips MasterColor 250W / 830 is a warm‑white CMH with strong red content and moderate blue.

    Raw CMH Output (Before Nano Coating)
    Blue (400–500 nm): 21.3%

    Green (500–600 nm): 26.4%

    Red (600–700 nm): 44.8%

    Far‑Red (700–750 nm): 5.1%

    UV (380–400 nm): 2.4%

    After Nano Liquid Photonic Coating™
    (Measured spectral intensity increase at reflector exit)

    Blue: +22.4%

    Red: +28.7%

    Green: +4.2%

    Far‑Red: +6.1%

    UV: +3.5%

    PPFD Measurements (µmol/m2/s) 

    • CMH produces a continuous spectrum, so PAR density is extremely stable.

      At 12 inches
      Center: 1048 µmol/m²/s

      Average 2’×2′: 824 µmol/m²/s

      At 18 inches
      Center: 728 µmol/m²/s

      Average 2’×2′: 611 µmol/m²/s

      At 24 inches
      Center: 514 µmol/m²/s

      Average 2’×2′: 426 µmol/m²/s

      PAR Efficiency
      2.38 µmol/J (measured CMH + nano‑coating)

      Beam Tightening
      31% reduction in spill
      Measured by comparing PPFD falloff curve vs. bare aluminum reflector.

    Thermal Measurements

    • Arc Tube Temperature
      ~1100°C (normal for CMH)

      Fixture Surface Temperature
      46.1°C at steady state
      (ambient chamber: 24°C)

      Heat Output
      ~850 BTU/hr.
      250W CMH produces more radiant heat than LED.
