Different types of dimming curves may be incorporated in dimmers, software for lighting control systems, and output devices like LED drivers irrespective of the actual protocol used to communicate between them.
Steve Mesh Talks Dimming Curves, Part 1
Let’s talk about dimming and dimming curves, and a variety of attributes that you should consider, inquire about, then specify what you actually want.
HLB’s C. Webster Marsh and Adam Levine on Digital Lighting Control Protocols
C. Webster Marsh, Designer with lighting design firm Horton Lees Brogden Lighting Design, provides the final installment on his series of articles about dimming and lighting control protocols. In this last installment, he teams up with HLB’s Adam Levine to tackle digital control protocols, covering when and how to specify it, and how to overcome some of the challenges.
HLB’s Elizabeth Johnson and C. Webster Marsh on Analog Dimming
“Communication is key to ensuring compatibility between controllers and drivers,” write Elizabeth Johnson, Senior Associate, and C. Webster Marsh, Designer, of Horton Lees Brogden Lighting Design in an article about analog dimming.
Avoiding and Resolving Issues with Products That Don’t Dim as Expected
With the right combination of dimmer and solid-state driver for LED products, dimming performance can achieve excellent results from 100% all the way to dark, smoothly and predictably, says Kevin Willmorth in his latest exclusive contribution. However, when the combination is wrong, many undesirable effects may occur, he points out. Investigating the reasons for these issues requires a basic understanding of where issues can arise.
Dimming Lamps and Luminaires
Eaton’s The Lighting Resource recently published an article about dimming LED lamps and luminaires.
Dimming TLED and LED HID Replacement Lamps
When evaluating an existing lighting system, the owner can do nothing, something or everything. Doing nothing abandons operating cost savings. Doing something entails replacing lamps and installing some automatic controls. Doing everything involves installing a new lighting and control system. As many owners opt for the “something” option, demand for LED replacement lamps continues to […]
The Twisted Road of Dimming Curves
Guest post by Kevin Willmorth. Superficially, dimming seems to be a simple operation. Turn a knob, slide a bar, or touch a screen to change light levels – done and done. This simplistic form of dimming was once applicable to resistance loads (incandescent lamps) using rheostat controls. The combination creates a naturally feeling dimming profile, […]
Lighting Controls for Dummies
In “Lighting Controls for Dummies,” a presentation at 2016 LEDucation in NYC, Andrea Hartranft, LC, IALD, of Hartranft Lighting Design, LLC, attempts to demystify lighting control vocabulary and provide a better understanding of solid-state dimming.

New Research Finds LEDs Favorable in Videoconferencing
According to new research by Lutron Electronics, lighting for video conferencing (VTC) applications must accommodate the visual requirements of the people and the camera, and provide visibility of any display materials, especially to remote participants. Achieving the proper lighting balance requires the right combination of fixtures and the right combination of control strategies. While linear […]
