Nano Liquid Photonic Coating Reflector — Manufacturer-Reported Technical Specifications
Philips MasterColor 250W / 830 CMH + Nano Liquid Photonic Coating™ reflector
The specifications on this page come from Nano Grow Light's own internal prototype testing using the equipment listed below. They are manufacturer-reported figures and have not been independently verified by a third-party or accredited lab.
Test Environment: controlled chamber at 24°C, 55% RH
Equipment used for internal testing: Apogee MQ-610 full-spectrum PAR meter, Ocean Optics USB4000 spectrometer, FLIR E6 thermal camera
Fixture height tested: 12in, 18in, 24in
Reflector: high-purity aluminum + Nano Liquid Photonic Coating™
Product: Nano Liquid Photonic Coating™ Reflector
Lamp compatibility: Philips MasterColor 250W / 830 CMH
Spectral Distribution (Manufacturer-Reported Internal Testing)
The Philips MasterColor 250W/830 is a warm-white CMH lamp 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™ (manufacturer-reported spectral intensity change at reflector exit):
Blue: +22.4% Red: +28.7% Green: +4.2% Far-Red: +6.1% UV: +3.5%
PPFD Measurements (µmol/m²/s) — Manufacturer-Reported
CMH lamps produce a continuous spectrum, so reported PAR density is stable across the internal test runs.
At 12 inches: center 1040 µmol/m²/s, average across a 2x2 ft area 824 µmol/m²/s
At 18 inches: center 720 µmol/m²/s, average across a 2x2 ft area 611 µmol/m²/s
At 24 inches: center 510 µmol/m²/s, average across a 2x2 ft area 426 µmol/m²/s
PAR efficiency: 2.38 µmol/J (manufacturer-reported, CMH + Nano Liquid Photonic Coating)
Beam tightening: 31% reduction in spill compared with a bare aluminum reflector, based on internal PPFD falloff comparison
Thermal Measurements — Manufacturer-Reported
Arc tube temperature: approximately 1100°C (normal operating range for CMH)
Fixture surface temperature: approximately 45°C at steady state (ambient chamber: 24°C)
Heat output: approximately 340 BTU/hr. A 250W CMH lamp produces more radiant heat than a comparable LED fixture.
Nano-material thermal behavior (internal observation): no discoloration, no delamination, no reflectance drop after a 72-hour burn-in, and no structural change under arc-tube radiant load.
Reflectance Measurements — Manufacturer-Reported
Bare aluminum reflector: visible reflectance 92.1%, PAR reflectance 94.0%
Nano Liquid Photonic Coating™: visible reflectance 97.4%, PAR reflectance 98.7%, blue-band reflectance 99.2%, red-band reflectance 99.3%
Nano-cluster size (SEM imaging of this test sample): 23-79 nanometers, within the coating's general 20-80 nanometer cluster range. Coating thickness on this test sample: approximately 3.5 microns (general cured range across production units: 2-6 microns).
Photonic Amplification Metrics — Manufacturer-Reported Internal Testing
Blue spectrum gain: +22.4% Red spectrum gain: +28.7% PAR concentration factor: 1.34x Beam tightening coefficient: 31% reduction in spill
