Using the most appropriate light source, lamp, and luminaire is an important technique to reduce energy use. Below are some of the completed projects related to lighting technology and equipment.

LED and HID Horticultural Luminaire Testing
The LRC examined 13 horticultural luminaires, including LED,
HPS, and MH products. The report also provides a framework for testing and evaluating additional horticultural luminaires on an equal-PPFD (photosynthetic photon flux density) basis.
Residential LED Demonstrations
In support of NYSERDA's Residential Emerging Technologies and Accelerated Commercialization (ETAC) initiative, the LRC demonstrated the effectiveness of LED lighting in 11 residences across New York State in 2015 through 2017. The lighting included LED bulbs and dedicated LED fixtures, in both new and existing homes. The report discusses energy savings, payback periods, occupant acceptance, and installer experiences.

Pin-base LED Lamps
This is an accessible guide for contractors and specifiers who are replacing existing CFL pin-base lamps with new LED lamps. Factors that should be taken into consideration include ballast compatibility, ballast age, and power demand of the current lamps. The guide was published in 2016.

Mogul-base LED Lamps
Mogul-base LED replacement lamps are marketed as equivalent replacements for incumbent HID lamps. This 2015 study, published by the Bonneville Power Administration, included pilot testing, apllication efficacy calculations, brightness calcualations, and high temperature testing.

LED Lighting Guidance
This is an interactive video presentation produced in 2013 to assist contractors, building professionals, and other lighting installers with the often confusing process of selecting and installing solid-state lighting equipment for a particular application. Topics of the video include product selection, advantages and challenges of LED products, economic calculations, installation tips, and links to other available resources. Viewers can earn professional continuing education credits by watching the video and using the interactive features. Adobe Flash and a broadband internet connection are required.

LED Troffer Specification Webinar
The Lighting Energy Alliance (LEA) at Rensselaer’s Lighting Research Center (LRC) presented this webinar on specifying LED troffers and retrofit kits on October 21, 2015. The speaker was Jeremy Snyder. Topics included specifying troffers that provide adequate illuminance, maximize energy savings, maximize occupant satisfaction, and meet payback period requirements. The document “LED Troffer Specification Guidance,” below, summarizes the content of the webinar. The webinar was intended for energy efficiency specialists who are not lighting experts.

LED Troffer Specification Guidance
This is an accessible guide for contractors and specifiers who are replacing existing fluorescent troffers with new LED troffers or retrofit kits. Factors that should be taken into consideration include providing adequate illuminance, energy savings, occupant satisfaction, payback period, and using lighting controls. The guide was published in 2015.

Plasma Lighting Systems
Plasma lighting systems, also known as electrodeless high-intensity discharge (HID), light-emitting plasma (LEP), high-efficiency plasma (HEP), or advanced plasma lighting (APL) are marketed primarily for high-bay and outdoor lighting applications. This 2013 National Lighting Product Information Program (NLPIP) report helps lighting specifiers to understand plasma lighting systems and their performance characteristics, including light output, system efficacy, color characteristics, lumen maintenance, and rated life. This report also provides information about operating orientation, dimming, warm-up, and restrike times, electromagnetic interference and compatibility (EMI/EMC), and ultraviolet (UV) radiation.

LED Streetlights
This 2011 National Lighting Product Information Program (NLPIP) report details the results of a study of LED streetlights for local roads. A companion report discusses LED streetlights for collector roads. Although the technology has advanced since the report was published, the recommended evaluation methods are still relevant today, and have been adopted by the lighting industry.

How to Upgrade Incandescent Bulbs in Residences
If you’ve shopped for replacement light bulbs, you probably noticed that you have many options and the alternative bulbs are more expensive. This interactive video presentation, produced in 2011, provides this step-by-step guide to choosing replacement light bulbs. To watch this, you will need a broadband internet connection and you must have Flash 10 or higher installed.

Lighting Terminology
Designers, specifiers, and manufacturers within the lighting industry use unique terms and concepts, which have evolved into professional usage over a period of time and have been officially defined by professional bodies such as the Illuminating Engineering Society of North America (IESNA). This is a resource to learn what "lumen," "illuminance," "CCT," and other terms mean.
LED Residential Under-cabinet Testing
This 2010 National Lighting Product Information report provides information about LED under-cabinet luminaires for kitchens that were available in consumer-oriented retail stores in the Albany, New York, area in the spring of 2009. The products were tested to determine the amount of light each provides on countertop and backsplash areas, the uniformity and color of the light, and the efficacy of the luminaires.

CFL Tips
CFLs can help save the environment and save you money. However, “going green” sometimes requires a little insight or planning. So, to help manage your CFL expectations and become an informed consumer, the LRC has outlined some facts and guidelines to assist you.
CFL Testing
This 2005 National Lighting Product Information report contains performance data for compact fluorescent lamps (CFLs) rated at or above 13 watts that were purchased from 1999 through 2005. The report includes NLPIP test data and manufacturers' data on both self-ballasted CFLs and modular CFL products that are sold with ballast and lamp packaged as a single unit.

CFL Residential Downlight Testing
This 2008 National Lighting Product Information report presents photometric, electrical, and thermal performance data for selected CFL residential downlights that qualify for ENERGY STAR® approval. Since 1980, the trend in residential new construction and remodeling has been to install recessed downlights as the predominant luminaire. Their clean, low-profile appearance appeals to many consumers. This report examines recessed downlight components, installation, operation, and performance.

PEARL Testing Program
The completed Program for the Evaluation and Analysis of Residential Lighting (PEARL) was a watchdog program that operated from 2000 through 2009. It was created in response to complaints received about the performance of certain ENERGY STAR lighting products and the lack of a self-policing mechanism within the lighting industry at the time that would ensure the reliability of these products and their compliance with ENERGY STAR specifications. To remedy these problems, PEARL purchased and tested 185 models of compact fluorescent lamps and 52 models of luminaires.

Integrated Skylight Luminaire
The Integrated Skylight Luminaire combines a skylight, a sunlight diffuser box, and an electric lighting system. A photosensor control system automatically dims or switches electric lights in response to daylight. This 2003 DELTA (Demonstration and Evaluation of Lighting Technologies and Applications) publication documents the field performance of a prototype skylight for warehouses that incorporates fluorescent lighting and an automatic control system.
