A new category of HID replacement lamps has arrived that are definitely not “corn cobs.” Their high lumen output LED filament lamps in traditional HID lamp form factors. I’ve found wattages as high as 42W (LED) that claim to replace up to 175W Metal Halide or HPS system watts (HID lamp + ballast), providing up to 75% energy savings.

A variety of new and updated ANSI standards address topics as diverse as sky glow, UV-LED Performance, expanded digital lighting control, and tunable-white SSL products. Below are quick summaries of each one, with links to more information.

In February, 2022, NEMA published NEMA LL-10, Replacing HID Lamps with LED Lamps: Light Output Equivalency Claims. This document describes a method for claiming equivalency of LED lamps to the HID lamps they replace.

EC&M Magazine recently ran an article about the value of sensors, IoT, and Smart Lighting Data. Energy ROI is an obvious benefit of advanced controls, but is often insufficient to justify the costs, after LED lighting has already slashed lighting energy use by more than 50%. In some places, lighting controls are installed to meet local code requirements.

LIGHTGLASS is a windowlight, an architectural element that brings the experience of a daylit window into any space. Through the integration of the latest LED lighting technology into the form and materials of a window, LIGHTGLASS is nearly indiscernible from a real window.
