Competitive Analysis, Color Rendering in White Light 
Comparing Metal Halide, Fluorescent, and Solid State Technologies 

This study compares the color rendition characteristics of the threemost common commercial lighting technologies; HID (high pressure sodium and metal halide), fluorescent, and solid state. This document addresses the color rendition of the white light used in commercial ambient lighting and the perception of color relative to the industry’s only color measurement scale. Download white paper

Comparing Metal Halide, Fluorescent and Solid State Technologies
This study compares the costs and characteristics of the three most common high bay lighting technologies: metal halide, fluorescent and solid state. It is intended to provide the end user with an understanding of Total Cost of Ownership (TCO) over various periods of time and differing daily operating hours. Using initial investment, operating cost and maintenance cost, we’ll provide a basis for comparison that can be extrapolated to specific installations. Download white paper

What the T5 Industry Doesn't Want You to KnowWhat the T5 Industry Doesn't Want You to Know
The T5 is the dying breath of the fluorescent technology. The chart on the right (published by Philips) compares their 360W T5 to their 460W HID. Cireon high bays of 180W deliver more light than a 6-bulb 54W T5—and with half the energy. A 40% reduction in energy is necessary to qualify for the full $0.60/ft2 the EPAct tax deduction. The T5’s reduction to 360W from 460W is only 22%, while the Cireon 180W SSL energy reduction is 61%—qualifying for the full Federal tax deduction. Download white paper

Lighting Industry – Structure and technology in the transition to solid stateLighting Industry – Structure and technology in the transition to solid state
Incandescent and fluorescent lighting are headed the way of Edison’s phonograph and other 19th century technologies. The transition to solid state affords new capabilities—and substantial efficiencies. Download white paper


Luminaire Output RealitiesLuminaire Output Realities
Process improvements continually increase LED outputs (in Cireon’s case the Philips Luxeon ES). Luminaire manufacturers contract LM-79 data periodically to heighten their performance data. As a result, the more recent the data, the higher the performance appears; this is not necessarily true. Download white paper

Thermal Management in Solid State LightingThermal Management in Solid State Lighting
Thermal Conduction and Convection in Passive Thermal Management
Thermal management is critical to the long life of the LEDs used in a Solid State Luminaire (SSL). This document provides the SSL consumer a fundamental knowledge of how the science of thermodynamic physics applies to the SSL, the methods used in SSL thermal management, and how effective thermal management directly relates to measurable LED performance over time.

DOE Supporting U.S. Manufacturing Growth

DOE’s solid-state lighting (SSL) manufacturing R&D initiative is a collaboration between the federal government and the lighting industry to develop cost-cutting measures in manufacturing LEDs, OLEDs and associated equipment, supplies and components in an effort to maintain the U.S. market and the jobs it creates.
