Lighting: Our team of expert electrical engineers will help you transform darkness to light in all of your projects by combining beauty, utility, and efficiency. Together they make something truly spectacular.Our highly trained electrical engineers are experts at engineering exterior and interior lighting and lighting controls. So what does this mean? Exterior lighting now needs to meet codes for dark sky and light trespass control, meaning that the light needs to all be aimed downward and be cut off to avoid lighting adjacent properties. LED lights are being used almost exclusively for exterior applications because their extremely long life means fewer replacements requiring the use of expensive lifts. Interior lighting is both an art and a science. Often architects will select specific fixtures for aesthetically sensitive areas within buildings.LED lights are often selected now for their energy efficiency, long life, and ability to be dimmed where daylight controls are used. LEDs are also capable of producing an array of colors which are increasingly being used outside and inside of buildings. G&M has completed the St. Louis County Government Services Center in Duluth, MN, which is a complete LED fixture retrofit with daylight controls.
