The National Electrical Manufacturers Association (NEMA) recently published NEMA 77-2017 Temporal Light Artifacts: Test Methods and Guidance for Acceptance Criteria. Temporal Light Artifacts (TLA) are undesired changes in visual perception induced by a light stimulus whose luminance or spectral distribution fluctuates with time, such as flicker and stroboscopic effect. This new lighting standard makes recommendations […]

NEMA Publishes NEMA BL 3-2013 Dimming Ballast Energy Performance
The National Electrical Manufacturers Association recently published NEMA BL 3-2013 Dimming Ballast Energy Performance. This standard provides a methodology for applying existing test methods for program start ballasts to fluorescent dimming ballasts. It also provides a method to calculate ballast luminous efficiency (BLE) for fluorescent dimming ballasts. Information for proper lamp and ballast compatibility for […]
Last Chance for Commercial Buildings Deduction?
The Energy Policy Act of 2005 created the Energy-Efficient Commercial Buildings Tax Deduction (CBTD) to encourage owner investment in energy-efficient building systems. The CBTD establishes a special tax deduction rewarding investment in energy-efficient interior lighting, HVAC/hot water systems and building envelope, subject to a cap of up to $1.80/sq.ft. It’s an accelerated tax deduction, meaning […]
