Decoding ANSI Codes

An ANSI code is a series of letters and/or numbers that can be found on High-Intensity Discharge (HID) and Halogen lamps and ballasts. While ANSI coded lamps are slowly being phased out in favor of LED systems, ANSI codes are still useful when matching HID lamps with ballast or vice versa. The ANSI code gets its name from the American National Standards Institute and is used across all industries to ensure uniform identification and performance among commercial products. Essentially, ANSI codes allow one to tell at a glance what the product is and its intended usage. This article will discuss all of the meanings of ANSI codes in lighting and why they are useful to consumers and manufacturers alike.
