High mast light is a kind of on-site lighting fixture, which is usually used to provide light to large areas, such as storage, transportation, parking lots, stadiums and sports facilities, etc. from a very high installation height. High-Mast Lighting fixtures are usually installed on 40ft-150ft poles with four to sixteen lights installed on each pole.
Please kindly check some image examples of outdoor high mast lighting fixtures that you may be familiar with.
There are some inherent characteristics in all HID lights. They can give rise to issues for those outdoor lighting for a facility or organization.
Common wattages of HID lamps used in traditional High mast lighting fixtures range from 400w to 2000w. The higher light output needs the higher wattages. A 1000 watts or 2000watts HID lamp (very common wattage for high mast light fixture) costs up to $6,300 and $12,500 per lamp per year in electricity cost alone.
Maintenance costs are usually a great focus for outdoor lighting such as high mast lamp fixture. Besides the concerns of high-mast fixture’ lifetime, it will also be easily lead to interference with the daily activities of customers or employees when replacing lamps or ballasts. It may require up to $2,000 in manpower and materials to maintain one outdoor HID high-mast lighting in three years.
According to the kind of HID Lamps your building or facility uses, it can vary evidently in the performance characteristics of your high-mast fixture. For instance, you can see the light that is "Whiter" when you use the Metal Halide lamp. However, these kinds of lights tend to accelerate lumen degradation, which means that the light output of the lights decreases rapidly after initial mounting, causing a decrease in the overall lifetime of the lamps (We've all seen those “pink” High-Mast Lightings, which are hard to offer any lighting on the ground).You can see the longer “useful” lifetime when you use High Pressure Sodium, because the lumen degradation of this type of lamp is less than metal halides’. However, it is with a very low Color Rendering Index (CRI) as its fuel structure provides a really “Orange” light. By and large, you trade your longer lifetime for poorer quality light from a visual point of view.
LED Outdoor lighting fixtures, such as High Mast LED Lighting Fixtures, offer a few great advantages for large area applications due to the way they GENERATE and DISTRIBUTE light. Different with HID lamps that generate light via the consumption of a “fuel source” , Light Emitting Diodes (LED) do it through semi-conductor. With regard to " distributing " light, LED lighting fixtures usually use “Multi-Point” sources, which implies that LED lighting fixtures have multiple diodes and separate optical elements. If you compare the distributing light of HID lighting fixtures (there is a bulb and reflectors in the lamp), the consequence is that the light of LED is more equably “distributed’ on a surface.
Normally, the power of High Mast Led light fixtures ranges from 209w to 750w, which usually leads to 50% to 80% energy consumption reduction. This is the consequence of how light is produced (see above). It means that your facility can save up to $8000 for one light each year in electricity bills.
Likewise, because of the way of LED’s generating light, it is quite different in the way that it progresses through its functional life. Despite the significant reduction in fuel source, LED (Light-Emitting Diode) fixtures degrade their light output really slowly over time rather than Stop working properly at once. Consequently, the lifetime of LED fixtures (usually more than 100,000 hours) can be evidently longer than that of HID fixtures. This in turn greatly cuts down the bill of maintaining parking lots and area fixtures over a longer lifetime.
Moving on to how the LED lighting fixtures “Distribute” light: It is reason of multi point design that Outdoor led high mast lighting fixtures for large area and site usually offer a quite uniform distribution of light pattern. It means that, when the distance of the fixture or the pole varies, there is less change in the light level across a given surface. HID lamps usually generate a "Bright Spot" under the lamps. With the increase of distance from the lamp pole, the brightness decreases sharply. This problem can be alleviated by uniform distribution of LEDs. As comparing to HID, the foot candle from LED conversion are more evenly distributed. Besides the uniform distribution of light, LEDs can be used at a range of color temperatures, thus offering a range of options to raise the visual perception of “BRIGHTNESS.”
The first is to communicate with manufacturers' neutral suppliers of LED lighting solutions provider. Why is this method opposite of the company you might have used in the past few years? Unless that company focuses on offering LED solutions, it is unlikely that they will have the performance-centric mentality needed to achieve the desired results of the lighting conversion in the outdoor high mast lights. A key step in any LED projects is to understand that LED technology is not a commodity. Previous decades included building facility managers and owners assessing product options purely based on cost, assuming that all options considered were of equal quality.
Solution-centric suppliers should ask you questions about project objectives. Are there energy reduction targets, lighting performance requirements, and budget constraints, etc? The right partners will expect to know the results you want rather than just what specific products they could sell to you. It is unequal for all LED products. For different applications, different manufacturers have different value levels. You will finally get the best result through working with companies, who have the product expertise to recommend solutions that meet your project priorities.
