Low-Wattage, Integral ballasted Ceramic Metal Halide

Summary

Low-Wattage, Integral ballasted Ceramic Metal Halide

Track Lighting: Low-Wattage Ceramic Metal Halide vs. Halogen

Self-ballasted ceramic metal halide lamps offer an energy efficient alternative to directional halogen lamps used in commercial display applications. No new fixture is required.

Synopsis:

Ceramic metal halide is a proven technology and the pulse-start,self-ballasted products can provide immediate energy savings, as well as life-cycle cost savings, over standard halogen and Halogen IR technology, in track lighting for commercial applications with 10 hours or longer daily operation. These low-wattage lamps are available in a warmer color (3000K) than traditional products and the color rendering above 80 makes them suitable for retail appllications. The lamps do not require new fixtures or electricians to install them. They also emit less damaging light than halogen sources which can shorten the life or fade the colors of items illuminated by them. As federal efficiency standards are enacted and energy codes reduce the lighting power density allowances, even on lamp/ballast replacements in many cases, this product offers a relatively low-cost retrofit.

Energy Savings: 70%

Energy Savings Rating: Limited Assessment What's this?

Level	Status	Description
1	Concept not validated	Claims of energy savings may not be credible due to lack of documentation or validation by unbiased experts.
2	Concept validated:	An unbiased expert has validated efficiency concepts through technical review and calculations based on engineering principles.
3	Limited assessment	An unbiased expert has measured technology characteristics and factors of energy use through one or more tests in typical applications with a clear baseline.
4	Extensive assessment	Additional testing in relevant applications and environments has increased knowledge of performance across a broad range of products, applications, and system conditions.
5	Comprehensive analysis	Results of lab and field tests have been used to develop methods for reliable prediction of performance across the range of intended applications.

Track Lighting: Low-Wattage Ceramic Metal Halide vs. Halogen

Self-ballasted ceramic metal halide lamps offer an energy efficient alternative to directional halogen lamps used in commercial display applications. No new fixture is required.

Item ID: 218

Sector: Commercial

Energy System: Lighting--Lamps & Ballasts

Technical Advisory Group: 2009 Lighting TAG (#1)

Synopsis:

Baseline Example:

Baseline Description: 65W halogen lamp
Baseline Energy Use: 325 kWh per year per unit

Comments:

A typical retail track display lamp is 65W halogen. They often operate at least 5000 hours per year, which is what this baseline figure is based on, but many can operate even more, up to 24/7, or 8760 hours per year.

Manufacturer's Energy Savings Claims: Currently no data available.

Best Estimate of Energy Savings:

"Typical" Savings: 70%
Energy Savings Reliability: 3 - Limited Assessment

Comments:

Based on estimates from research done by the Building Technologies Office of the US DOE. They use 24.8 lpw for the typical baseline efficiency, and 67.5 lpw for the ceramic metal halide. If the CMH product is installed on a pre-existing incandescent dimming system it could be damaged and have a very short life and therefore energy savings.

A low power factor product could incur power factor penalties in some cases.

Energy Use of Emerging Technology:

97.5 kWh per unit per year What's this?

Energy Use of an Emerging Technology is based upon the following algorithm.

Baseline Energy Use - (Baseline Energy Use * Best Estimate of Energy Savings (either Typical savings OR the high range of savings.))

Technical Potential:
Units: unit
Potential number of units replaced by this technology: 1,000,000
Comments:

Based on estimates for halogen directional lighting in commercial buildings 2010 U.S. Lighting Market Characterization, Navigant for U.S. DOE, 2012, Table 4-1: “Estimated Inventory of Lamps in the U.S. by End-Use Sector in 2010”

Regional Technical Potential:
0.23 TWh per year
26 aMW
What's this?

Regional Technical Potential of an Emerging Technology is calculated as follows:

Baseline Energy Use * Estimate of Energy Savings (either Typical savings OR the high range of savings) * Technical Potential (potential number of units replaced by the Emerging Technology)

First Cost:

Installed first cost per: unit

Comments:

Costs of standard incandescent halogen reflector lamps are under $5.00 each, and the infrared models tend to be almost three times more. Online prices found the GE CMH product at $138, the Philips around $80, and Sylvania's around $80 with lamp prices always dependent of many factors.

Cost Effectiveness:

Simple payback, new construction (years): N/A

Simple payback, retrofit (years): N/A

What's this?

Cost Effectiveness is calculated using baseline energy use, best estimate of typical energy savings, and first cost. It does not account for factors such as impacts on O&M costs (which could be significant if product life is greatly extended) or savings of non-electric fuels such as natural gas. Actual overall cost effectiveness could be significantly different based on these other factors.

Comments:

Using a standard 75 halogen lamp at $5.00 each with a life of 2500 hours would require 6 lamps for $30, operate for 3550 hours annually, at $0.10 kWh for the life of one 25 W, CMH lamp would be $142 per socket for 15,000 hours, plus labor to install 6 lamps, and assuming no cost increase or including demand charges.

Using 60 W halogen IR, with the same lumen output as the standard 75W, plus $48 for 4 lamps, 3550 hours/yr, 21.3 kWh /yr for 4.2 years for $137/socket, plus labor to install 4 lamps, and assuming no cost increase or including demand charges.

Using a 25 W CMH, $9 energy cost per year for $37 per life plus lamp is $117 per socket, without demand charges or cost increases.
