MR-16 LED Replacement Lamps: Electrical Compatibility and Performance


As light emitting diode (LED) MR16 lamps become more prevalent in the commercial market, both residential and commercial end‐users are considering these lamps as replacements for currently installed halogen incandescent MR16 sources. While the energy savings associated with LED lamp replacements is evident, the compatibility of LED MR16 lamps with existing electrical hardware is not. In one‐to‐one lamp retrofits, MR16 LED lamps often demonstrate negative performance characteristics such as visible flicker and audible humming.

Codes and Standards Enhancement—Quality Demonstration Program


The CASE-Q DP Program Manual contains the requirements and processes for future field demonstrations. It can be used by any team wishing to conduct a sound, thorough and well-documented technology demonstration. In addition to providing this resource, the CASE-Q DP directly supports identification, selection, installation and performance assessments of energy-efficient building technologies ready for current or near-term inclusion in California's Codes and Standards Enhancement (CASE) initiatives.

Field Luminance Mapping of the Sky


IES Annual Conference 2010—When sky luminance distributions are measured far from a laboratory facility, portable and inexpensive instruments are useful. High dynamic range (HDR) photography has become a practical method for sky luminance mapping. However, long exposure photography directed at the sun can cause severe damage to digital camera sensors. To avoid this problem, a system was designed that integrates an adjustable shading disk with an HDR camera.

LED Lamp Testing at UC Davis

LED Lamp Testing at UC Davis

Since its establishment in 2003, the California Lighting Technology Center (CLTC) at UC Davis has conducted extended photometric and electrical testing of light sources. During the last 18 years, CLTC has been successful in establishing an array of testing facilities, some with unique capabilities, including complete photometric and electrical testing laboratories, and chambers for lifecycle testing under customized operational conditions.
