The Sky Glow Comparison Tool is a simplified method for comparing lighting products’ contributions to sky glow that allows the user to vary the traditional output characteristics (e.g., spectral content, output level, percent uplight) of each product being compared. 

Spectrally Enhanced Lighting

Spectrally Enhanced Lighting (SEL) is a cost-effective, low-risk design method for achieving significant energy savings by shifting lamp color from the warmer to the cooler (whiter) end of the color spectrum, more closely matching daylight.

Residential Lighting Usage Estimate Tool

The Residential Lighting Usage Estimate Tool is a companion to the report, "Residential Lighting End-Use Consumption Study," which developed a regional estimation framework within a national sample design that allows for the estimation of lamp usage and energy consumption. The tool contains the full set of estimates produced by methodology described in the study.

Retrofit Financial Analysis Tool

The Retrofit Financial Analysis Tool provides municipalities, utilities, and other organizations a method of analyzing the cost and return-on-investment from lighting efficiency projects.
