Power Supplies
All of our lighting systems are powered from low voltage transformers which are made from nearly entirely stainless steel and are encased in an entirely stainless steel housing. The windings of our transformers are completely encapsulated in epoxy for quiet, cool, safe, and reliable operations. Clients oftentimes have specific questions regarding how their lighting system turns on and off. After weighing all of the options: switches, remotes, digital timers – just to name a few – most of our clients choose to have a photo eye installed. This device is a sun sensor which determines dusk and thereby turns on the lighting system. Generally we install a 1930s-style Intermatic™ dial timer that uses the green and red pegs. The green pegs turn the system on, and the red pegs turn the system off. We usually install these timers over digital timers, as our clients have told us they are more user-friendly. Most clients elect to set the system shut-off at 1A.M.
Wire
We use only the toughest wire available. Our wire is backed by a 10 year manufacturer’s corrosion warranty. Our supply wire is virtually impossible to cut through under normal conditions with a household shovel. However, in that case that the wire is physically damaged, neither our company nor the manufacturer will provide a warranty for it.
Wiring Connections
When we use the wiring technique most commonly referred to as hub and spoke. In this technique a supply cable is run out into the center of a group of fixtures, usually five fixtures or less. One single connection is made to connect the supply with these five fixtures that have factory-assembled soldered leads of twenty-five to fifty feet in length. This minimizes the number of field connections by 80%. These field connections are a leading cause of lighting system failures. When these connections are made, we use only solid brass barrel wire connectors. To the best of our knowledge, we are the only contractor in the region that uses this type of connection for lighting. This type of connection is more frequently seen in sensitive outdoor equipment such as traffic signals, security doors, and the like. It is known to be the second most reliable type of connection. Soldering is the only type of connection that is more reliable, but is unpractical in a field environment. In our experience we have never seen a brass barrel connector fail in a field application. Many of the lighting systems we replace do not work because all of the connections have corroded to the point where all connections must be replaced to work reliably. These connections carry a lifetime parts and labor warranty. |
