DMD have developed a series of webinars focused on specialized lighting applications such as sports lighting, tunnel lighting and roadway lighting and other presentations such as arc flash. These webinars are educational in nature, approximately one hour in length and available to our clients and Cities at no cost. To date, we have presented to over ten groups as of March 2021 with very positive feedback. Many of those who attended did not have a strong lighting background and found the presentation well explained and easy to understand. Please contact us if you are interesting in setting up an educational...

In December 2021, DMD have developed a lighting demo kit featuring various luminaire types and optical systems for various demos and mock-ups for lighting architectural features. The kit includes various colour changing linear and spot type luminaires and controls for developing and showcasing lighting effects. This will allow architects and Cities to review lighting effects so DMD can better specify requirements. DMD will be displaying various colours and textures on a wall and floor to review the various lighting effects. The system is also set-up to showcase lighting controls and to present lighting effects including chasing, flashing, color changing and dimming of the...

In September 2021, DMD staff undertook testing of cobra style luminaires in our warehouse facility with the goal being to assess various LED luminaire products with respect to discomfort glare. Discomfort glare is not well defined and is often the source of complaints from local residents located off the roadway. To this end, the IES has developed the Discomfort Glare in Night-Time Environments Committee of industry experts (of which DMD are a part of) to assess methods to both define and measure discomfort glare. The testing included luminous intensity measurements using a specially designed meter to measure actual candela levels. The point of this testing was to define differences in optical systems for various suppliers’ products as viewed on and off the roadways. Luminaires were mounted at 8m and measurements taken at four locations in a dark area. In addition, luminance and illuminance measurements were taken along with a visual rating from 1 to 7. Results were presented to the IES Discomfort Glare in Night-Time Environments Committee. Results showed some differences in various products and also showed luminous intensity measurements generally correlated with...
