The The quality of our cone is noteworthy; it is 10 inches in diameter and is made of spun .050" thick aluminum, which is more than double the thickness of some competitive units. We finish this cone with a durable baked yellow enamel which provides a highly visible daytime marker for your runway edges. The post that we use is made from electrical-grade PVC conduit which has UV stabilization and is rust- and corrosion-free. The lens is UV polycarbonate and is designed to magnify the light omnidirectionally from horizontal to about 15 degrees above the horizontal plane, which is needed for most approaches. The lens, along with the 15 watt long-life bulb (1000 hour), is a proven design that has been used successfully for many years. The lens are available in clear, amber, red, green, blue, red/green, red/clear, green/clear, and amber/clear. The split-lens units are of an internal design, which eliminates water leakage. Shields are also available so that the light is only visible for 180 degrees in direction. The ML-3 can be mounted in a variety of ways. The easiest is to pound an oversize pipe into the ground and simply insert the ML-3 into the pipe. This requires an extralong PVC post on the ML-3 and also wiring which is external to the post. This method poses a problem if the split lens are used. A method has to be devised to make sure the light cannot be rotated. This can be done with a set screw or similar device. The ML-3 can also be supplied with a post which is 4 inches longer than the installed height. This 4 inch post area is installed below ground level into the "V" groove of an angle iron stake and secured with a stainless steel hose clamp.This makes a neat installation since the wiring is internal to the post. Runway lights should be 14 inches total height above the ground. In areas of heavy snowfall the units can be 24 inches above the ground. Many governmental agencies are now recommending that the runway marker lights be placed 200 feet apart with 6 red/green units across each of the thresholds. We recommend that you contact your State agency to check on any requirements. Its possible that the spacing is at your option and that you could use solid green on each threshold thereby saving you money. Since low-intensity lights use little power, it is possible to wire your runway using #14 UF (direct burial) wire. A typical 3000 foot runway would need about 40 ML-3 units (using 200' & 6 threshold config.), which means that the total load would be only 600 watts. This translates into a current running in the feed line of only 5 AC amperes. It should be noted that each installation is unique, and someone with knowledge of voltage drop due to long lines be consulted. Most installations should not require lines greater than #14 wire between units and #12 wire from the source to the runway. Please call for more information on your installation. We can offer advice for most of your questions. Almost every installation is unique. Our units are high quality! We can give you a list of past installations in your area. Looking for ML-1 parts?
