LED Post Top Bulbs - LED Corn Bulbs

Shop a wide range of Post Top LED Corn Retrofits bulbs that replace HID and HPS Post Top lights. All bulbs backed by a 5 year warranty. Post top lights mount on poles usually placed near pathways, commercial buildings, educational complexes, roadways or parking lots. These outdoor light fixtures are generally fitted on poles ranging from 7 feet to 20 feet. Depending on the use, a pole might have several fixtures on it using different mounting methods. LED Post Top bulbs contain everything you need to produce light including the internal driver and heat sink. These bulbs are designed for a quick, fast and easy installation.

If you have ample space, IESNA recommends mounting high with high-wattage and well spaced for uniform lighting. Recommendations in pedestrian zones are mounting heights of 10 ft to 20 ft and 30 ft to 60 ft for larger spaces.

High-mounted, high-wattage post top fixtures disperse light in a broad range. Some municipalities and zones restrict mounting heights for lighting fixtures. It pays to first ask – especially if you are installing post top light fixtures afresh. IESNA recommends using more poles for low mounting heights. Also with lower LED wattages to ensure uniformity and reduce light wastage.

Tool-less openings on poles make it easy to unhook snaps that open hinged fixture doors. Re-lamping is much easier because juggling screwdrivers on a bucket truck is not easy. If the screws drop during installations 20 feet down, too much time is spent recovering them. Then getting back up again to complete the job.

Post top light fixtures are exposed to harsh weather conditions and vandalism. They need to be well built with high-quality materials to outlast the abuse. Three types of lens materials available: acrylic, polycarbonate, and glass. The latter is very brittle and damages.

Poly-carbonate lenses are the most durable lenses out there. Acrylic lenses come in a close second. Ensure you buy long-lasting LED post top retrofits. Make sure they have the right Ingress Protection- IP rating.

A well sealed light fixture will have an IP rating of 66 and above. This means that it's impermeable to dirt and wetness. The lenses last longer since dirt and water will not clump inside the fixture. The dirt reduces its light efficiency and destroys the electrical components.

Low quality lights placed wrong can obstruct surveillance cameras, compromising a property's security. Always match your light fixtures’ spectral output to your surveillance to ensure the cameras work.

There are many forms of light pollution. One is glare. It is excessive intense light that causes visual discomfort. There's also light trespass that happens when light creeps out to areas where it is not required. Sky glow occurs in urban areas, causing the over-brighten sky in residential spaces. There's also light clutter. This is excessive groups of light fixtures too bright due to the intensity and placement.

The IDA estimates that over 30% of all light produced is wasted. This annual loss of 22 billion kWh can compare to the cost of 12.9 million oil barrels or 3.6 million coal tons.

Light pollution and trespass affects commercial property areas and becomes a nuisance. IESNA advises post top light fixtures should have a well-controlled distribution of lumens. You should use LED light fixtures because they disperse their light in one direction. This controls upward light emissions that cause light pollution.

Place post top lights on the same level to cut the shadows that turn curbs and steps into tripping hazards. Dark areas between outdoor lights decrease the ability to see activities. Post top fixtures should be well spaced to cut dark spots that impair vision.

People perceive light in relation to its surroundings. Poor lit outdoor spaces look much darker when compared to bright lit spaces nearby. The spacing of post top fixtures on sidewalks affects the sidewalk's usage and appeal.

The Quality of Illumination

HID bulbs have limits in customization, efficiency, and wattage range, but LEDs do not. They are powerful and efficient. A LED light fixture of 6W to 9W is capable of providing as much light as a 60W HID light bulb.

With LEDs wattage does not quantify their level of brightness. So a metric known as a footcandle measures illuminance adequacy. Wattage measures the amount of electric power a light fixture utilizes. LEDs are so energy efficient they use less power to produce as much light as higher-wattage bulbs. Since you can’t retrofit HIDs with LEDs watt for watt, you use foot candles.

A footcandle (FC) equals one lumen of light per square foot of space. Foot-candles determine the amount of light enough for a space. The foot candles recommended by the IES for LED post top retrofits are as follows:
