One of the old school ways of setting up a dimming control desk setup for a draw bridge was to use a N1000 dimmer with a lot of 6 watt incandescent lamps. They need to dim the lights at night so that they can see the boat travel under the bridge. This control desk has 45 lights on it indicating some sort of condition, red, green and yellow lights. These lamps operate at 120 Volt.
Now we want to install a proven system using a lutron dimmer that would work as a dim to zero light. The LED light should be through hole, screw terminals, 1" penetration like the lights from the past. They also have to be Daylight visible within a control building.
The manufacturer of the previous lamp holders was Diallight.
