Los Angeles, CA (PressExposure) July 18, 2012 -- Liton is pleased to announce that its Mini-Arc and Architectural Recessed LED products now meet the highly accurate 3-Step MacAdam Ellipse Standard for chromaticity variation.
Liton Lighting LED Products have always conformed to ANSI standards for color temperature variation, which is what Energy Star requires.
The ANSI standard allows for a binning deviation of 175K +/- at 3000K and could vary from 2870K to 3190K and still be listed as 3000K. It doesn't sound like much but in critical applications it can make a big difference.
The more stringent standard, 3-step MacAdam Ellipses, is increasingly being called out by lighting designers, engineers and other specifiers. LEDs meeting this standard offer the least amount of chromatic variation.
The rule of thumb is that the more ellipses the wider the deviation. The current ANSI standard is equivalent to 7 Step Ellipses. This variance is usually acceptable to general purpose applications. The 3-Step MacAdam Ellipse standard is required for more critical applications where chromaticity variance must be limited or precisely controlled.
Liton also announces a new high 90 CRI option for its Mini-Arc and Architectural LED products as well.
