Good management is the basis for good results, and this maxim applies to light as well. This is why protocol systems that follow the industry standards provide the best-possible control options and can be extended to meet changing needs – while saving energy at the same time.

0-10V is an analog lighting control protocol. Basically, a 0-10V control applies a voltage between 0 and 10 volts DC to produce a varying intensity level. There are actually two existing 0-10V standards called current source (a theatrical dimming standard) and current sink (a dimming ballast standard).
Current sourcing controls for 0-10V are supported by the standard ESTA E1.3, Entertainment Technology – Lighting Control System – 0-10V Analog Control Protocol, Draft 9 June 1997. It defines 10V as 100% light level and 0V as off. Drivers using this protocol require the control to provide (source) the voltage.
There is an IEC standard for current sink controls - Standard 60929 Annex E. The standard requires that the ballast (or driver) provides full light output when the control voltage is 10 Volts (or above). As the control voltage is reduced by the control, the light level is reduced. At a control voltage of 1 volt, the ballast (driver) provides it’s minimum light level. Any voltage less than 1 volt is defined as minimum. For drivers that do not go to off at minimum, a separate relay or switching device is required.
DALI is an International Standard (IEC 62386) lighting control system, providing a single interface for all electronic control gear (light sources) and electronic control devices (lighting controllers).
The DALI Standard enables dimmable ballasts, transformers, relay modules, emergency fittings and controllers from different manufacturers to be mixed and matched into a single control system.
A DALI system provides designers, installers, building owners, facility managers and end-users with a powerful and flexible digital lighting system, with compatibility of supply from many sources.
One of the greatest advantages of DALI is that every light throughout a project can be individually controlled and queried. DALI lighting control enables wiring to be simpler, reduces the cost of installation and allows architects and designers to create high-performance lighting that is easily matched to the requirements of each building’s occupants.Read More
DMX is the standard protocol for controlling professional stage and lighting effects equipment, which is used, for example, in the dynamic lighting of showrooms and salesrooms as well as for exclusive displays of light and color in high-profile buildings, such as hotels and event centers.
The DMX protocol was orignally developed in 1986, with subsequent revisions in 1990, leading to the USITT (United States Institue for Theater Technologies) standard, referred to as DMX512/1990. In 2004, DMX grew again in to DMX512/A.
DMX uses serial RS485 physics for data transmission, in which the information (DMX frame) is transmitted as a difference signal on two lines. RS485 is relatively immune to EMC interference.
DMX came to offer a common standard that both console and fixture manufacturers were able to implement into their products, providing consumers with a predictable platform that worked industry wide.
The Casambi solution is based on Bluetooth Low Energy, the state-of-the-art wireless technology and the only low power wireless technology in all modern smartphones, tablets and even smart watches, making it the only mainstream and future proof low power radio technology in the world.
On top of Bluetooth Low Energy, the Casambi technology provides a mesh network where all the intelligence of the system is replicated in every node and, in such a way, creates a system with no single points of failure.
Casambi technology works with any manufacturer's range of existing luminaires or already installed wall switches but can also be easily integrated into LED drivers, LED bulbs or LED modules, creating an optimal solution in terms of ease of installation and functionality with minimal additional hardware and deployment costs.
