With Tim Cillessen
5/1/23 – Lighting Episode 310 (Full Version) – Tim Cillessen 37:01
With the kinds of customers Tim serves, good lighting can be a matter of life and death. Mines, factories, steel mills – all require lighting that isn’t going to melt, start a fire or blow up! Tim and his company, Dialight, keep sustainability at the forefront of their mission while helping customers achieve their environmental and safety goals. Tim does have one frequent customer complaint though: people can’t believe how dirty their facilities are once they’re properly lit! Tim Cillessen is Dialight’s VP of Sales, overseeing global sales as well as marketing and customer service operations to drive revenue growth and develop strategies to expand Dialight’s market share. Tim began his career as a Product Development Engineer, where he gained valuable experience in developing and testing instrumentation products for various industrial markets, eventually moving to work at Siemens as a Product Manager for Instrumentation and quickly rising the ranks to become their Head of Sales and Marketing for the Process Safety division – leading sales and marketing teams and developing solutions to increase safety in some of the toughest markets.

Good interview. Sustainability does not seem key with Dialight fixtures. There are no field-replaceable items in a Dialight non-hazardous fixture. All the high bays, low bays, and area lights are not field repairable in non-hazardous areas. What kind of sustainability is that? Why are there no replaceable parts, such as lenses, drivers, etc?
Thanks for the kind words Skip, the interview was pretty fun. However, if you look at some of our recent product launches over the past couple of years, you will see several products that have field repairable aspects: Reliant High Bay (both round and rectangular), High Output High Bay, Prosite Floodlight, GRP Linear, Bulkhead series and launched just this week the Prosite High Mast. In addition, almost all of our product have field replaceable lenses.
Our mission is to develop luminaires designed for the application that will withstand the environment for more than 10 years. That is where sustainability meets with reliability.
Well done Tim, Michael and Greg. Nice plugs for NAILD, NLB and its Trusted Warranty Program. Tim mentioned LED Traffic Signals. Before white LEDs were commercially viable, Dialight entered the Traffic Signal business with monochromatic Red, Yellow, Amber and Green LEDs. They are still in that business offering high quality modules with 15-year warranty! Consider the harsh environment inside a traffic signal. The ITE specification requires Dialight to ensure intensity, chromaticity and uniformity over a vast ambient temperature range, -40C to 74C. Dialight provides a temperature compensation/feedback loop to meet the standard. Regarding sustainability, you have replaced 135-watt incandescent bulbs with 6 watts of LED. The Red indication required a bucket truck to replace annually. Not anymore. I have Dialight Traffic Signals in my hometown that were bought and installed 20 years ago! Think of the tremendous energy and maintenance savings!
