Test Procedures for High-Intensity Discharge Lamps Proposed

Sandler, Travis & Rosenberg Trade Report

The Department of Energy is proposing to establish test procedures for high-intensity discharge lamps. Public comments on these procedures are due by Feb. 28, 2012, and a public meeting on this proposal (which will also be broadcast as a webinar) will be held Jan. 19.

According to DOE, the proposed test procedures would include measurement of parameters to enable calculation of lamp efficacy (in lumens per watt) and would also provide for the efficiency measurement of directional lamps using center beam intensity (in candelas) and beam angle. The proposed procedures would also measure lumen maintenance (i.e., the fraction or percentage of lamp light output relative to initial output, over time) at 40% and 70% of rated lamp lifetime. Correlated color temperature and color rendering index would also be measured as potential means to delineate equipment classes for HID lamps.
