Contents
  • Overview of electronically ballasted CMH benefits
  • Performance Comparisons
    • Accent Lighting
      • PAR30CMH vs. 100W Halogen HIR
    • General Downlighting
      • 100W ED17 CMH Electronic vs. Magnetic
      • 100W ED17 CMH vs. 2x42W CFL
      • 100W ED17 CMH vs. 2x32W U 2x2 Troffer
cmh general benefits review
CMH General Benefits Review
  • Outstanding Color
    • 80+ CRI in 3000K or 4100K
  • More punch and sparkle vs. fluorescent
  • 3X more energy efficient vs. halogen
  • 3-5X longer life vs. halogen
cmh electronic vs magnetic ballast
CMH Electronic vs. Magnetic Ballast
  • Color advantages
    • Uniform Lamp-to-Lamp Color Temperature
    • Consistent color temperature and CRI regardless of variations of input voltage
    • Stable color over life

Eliminates the traditional color shift problems

associated with Metal Halide lamps

cmh electronic vs magnetic ballast5
CMH Electronic vs. Magnetic Ballast
  • Performance Advantages
    • 10-17% more energy efficient
    • 10%+ higher mean lumens

Allows same light levels with fewer fixtures, or higher light levels with no increase in fixture or energy costs

cmh electronic vs magnetic ballast6
CMH Electronic vs. Magnetic Ballast
  • Operating Advantages
    • Quiet Operation
      • Sound “A” rated
    • Consistent lumen output regardless of variations in input voltage
      • 10% variation w/ magnetic causes up to 19% drop in lumens
    • Line Dip Tolerance
      • Lamps will not extinguish due to random voltage dips
    • Faster hot restrike and warm-up
    • No perceptible flicker
cmh electronic vs magnetic ballast7
CMH Electronic vs. Magnetic Ballast
  • Maintenance Advantages
    • 20% longer lamp life
    • End of life shut-down circuit

Longer relamping cycles / lower lamp replacement costs

Eliminates nuisance cycling and ballast damage

No need to wait for lamps to cycle to identify replacements

cmh electronic vs magnetic ballast8
CMH Electronic vs. Magnetic Ballast
  • Installation Advantages
    • Approximately 2/3 less amperage draw
      • Allows ~3X more fixtures per 20-amp circuit
    • Lighter weight
      • From this to this

Significantly reduces panel and branch circuit wiring costs

Easier to handle and install

Example 1: Accent Lighting39WPAR30CMH/FL25 vs. 100W PAR38HIR/FL25
  • 56% energy savings
    • 44 watts vs. 100 watts
    • Less heat in store
  • 230% higher CBCP
    • 11,000 vs. 6,300
  • 330% longer life
    • 10,000 hours vs. 3,000 Hours

Example 1: Accent Lighting39WPAR30CMH/FL25 vs. 100W PAR38HIR/FL25
  • Per Lamp Annual Operating Cost Savings

(at 12 hours per day, 7-Days/week, $.08/KWH)

    • Energy Cost: $15.41 vs. $35.04
    • Relamping Cost: $2.19 vs. $7.30
    • Total per fixture energy savings: $24.74
  • Replace multiple halogen lamps w/ single CMH…savings even more compelling
  • PLUS reduced HVAC equipment and operating costs
  • PLUS higher attainable footcandles/ luminance ratios for more dramatic displays
