Douglas Lighting Controls has manufactured and supplied lighting control equipment since 1962. Over the past nearly 50 years , Douglas has developed many lighting control firsts:

In the early 1960’s Douglas distributed the 2-wire relay, switches and panels for field assembly. Into the latter half of the decade, Douglas began to manufacture and install the first programmable lighting control system in North America using telecom technology.

The 1970’s marked a new era for Douglas Lighting Controls as we would go on to pioneer pre-assembled panels and promote pre-assembled lighting control systems as the standard for new construction projects.

The 1980’s saw the dawning of the personal computer era. Douglas would evolve, much like the world would evolve, as this magnificent tool would make its impact. Douglas Lighting Controls would take advantage of the numerous capabilities of the PC by incorporating it into our lighting controls systems and adding graphical control and data logging programs to our repertoire.

As various technologies made their way into the fabric of the controls industry in the 1990’s, Douglas Lighting Controls adopted the LonWorks control technology to a number of our control products and we officially joined the LonMark Lighting Control Standards group.

The 21st century opened to the world embracing the phenomenon that is the World Wide Web. The internet has simplified an innumerous amount of tasks and increased the accessibility for many control industries, including lighting controls. The early 2000’s saw Douglas Lighting Controls adding internet control and web access to our LonWorks lighting control product group.

Today, Douglas Lighting Controls Inc. continues to engineer, manufacture and distribute, lighting control products for the North American and International markets. We manufacture a full line of lighting control products from basic components to pre-assembled systems. Our products and systems are installed in thousands of buildings worldwide and we have come to be known for our reliable product and years of tremendous service.
