The scope of this paper is a discussion of issues related to the field replacement of drivers in LED lighting fixtures. This paper explains that several aspects must be considered to ensure the replacement driver will function in the same way as the original driver. The...
This Standard specifies the 0-10 volt control interface method and performance requirements for dimmable LED drivers, fluorescent ballasts and dimming control units where output power is adjustable between minimum/off and maximum via a control input signal. The interface may be from...
1.1 These requirements are intended to cover both self-ballasted lamps and self-ballasted lamp adapters rated 120 to 347 V AC nominal for connection to screw-base, pin-base, or recessed single contact (RSC or R7) lampholders. These devices are intended for use in accordance with the National...
This standard provides specifications for and operating characteristics of non-integral electronic drivers (power supplies) for LED devices, arrays, or systems intended for general lighting applications. Electronic drivers are devices that use semiconductors to control and...
1.1 These requirements apply to light-emitting diode (LED) retrofit kits that are intended to retrofit existing light sources or other components in previously installed luminaires that already comply with one of the standards in 3. 1.2 These kits are intended for use with: a) Luminaires...
This Standard describes the procedures to be followed and the precautions to be taken in measuring performance of LED drivers commonly used in general lighting, exterior lighting, and roadway lighting, and similar applications. The scope includes LED drivers that may...
The scope of this paper includes dimmable fluorescent ballast and Light Emitting Diode (LED) drivers that are controlled by 0-10 V (1-10 V) control input. This paper explains the relationship between the control input voltage and overall energy consumed by these ballasts and...
The purpose is to standardize LED Lamp specification sheets for HID Replacement and Retrofit Applications, as the means of communication of critical lamp characteristics such as: a. Intended use ballasts (if applicable) b. Reference circuit (if applicable) c. Identify input voltage...
This SIN applies to signals fitted with Dorman LED signal heads (all varieties) on a platform or less than 200m beyond a platform; NOTE: The highest risk is where drivers regularly stop in the same position which coincides with the position a phantom aspect can be witnessed. Stopping...
This white paper provides information about self-ballasted lamps and the implications these lamps present from a power quality perspective. It focuses on the use of self-ballasted lamps in residences and on residential power quality. Self-ballasted lamps have dedicated ballasts or drivers...

Low Voltage LED Wire UL 2592 1.1 These requirements cover single-conductor and multi-conductor, unjacketed, 18 - 10 AWG (0.807 - 5.16 mm2), low voltage LED wire rated 105°C - 250°C (221°F - 482°F), and 300 or 600 volts, suitable for installation in dry and damp, or wet locations....
INTRODUCTION For many years, the most common source type for sports lighting has been high intensity discharge (HID) lamps. More specifically, metal halide lamps have been used due to their high efficacy (lumens per watt) provided in a small package. Over the past decade, solid state lighting (SSL)...
Introduction Some outdoor luminaire installations are regulated by the National Electrical Safety Code (NESC)1 requirements. In general, utility operated facilities are required to comply with the NESC. In installations covered by the NESC, some luminaires have the neutral conductor terminal and...
