Huge Energy Saving
If there is one application that benefits the most from LED lighting it is High Mast Led Flood Light.
Energy consumption, resource conservation, maintenance, and long-term sustainability are important factors that should be taken into consideration for any lighting installation. High output lighting system consumes a considerable amount of electrical energy to produce light for high intensity wide area lighting. While HID floodlights have luminous efficacy (lumens per Watt, lm/W) comparable to LED counterparts - HPS lamps have an efficacy of 75 to 130 lm/W, LPS lamps have a high efficacy of 130 to 185 lm/W, and MH lamps have an efficacy average from 70 to 115 lm/W. High mast led flood light, use semiconductors that are more efficient and durable, and can have L70 lifetimes up to 50,000 hours. L70 lifetime is defined by Illuminating Engineering Society Standard LM-80-08 and describes the expected number of operating hours until the light output has dropped to 70% of initial levels. MH lamps (and most HID lamps) exhibit lamp lumen depreciation (LLD) characteristic. They have an initial light output at rated wattage (luminous efficacy), but then the lumen depreciation occurs most rapidly during the first 100-200 hours of operation (e.g. 20% depreciation). Over the life of operation, the lamp usually slowly loses lumen output from LLD. A typical 1500W MH floodlights, for example, can lose up to around 50% of its initial light output over a 3000 hour cumulative operation life. This means LED lights have a far more longer usable time than MH lamps. Today's white LEDs have a luminous efficacy average from 120 to 150 lm/W. Such as:Fanguang Lighting,professional led lighting manufacturer, mostly high mast led flood light is over 140~150lm/w, Moreover, it is practically possible to increase the luminous of high mast led flood light to as high as 200 lm/W with further improvements in the underlying materials and design. The economic benefits of LED lighting is obvious in view of its increased efficiency, extended lifetime, negligible maintenance investment, and the dramatically cut lamp cost which leads to a shorter payback time.
Better Light Quality
Metal halide light is very favorable in terms of high color rendering lighting, resulting in a high color rendering index (CRI) value in the range of 80-95. CRI is a measurement of color reproduction quality of artificial lighting products. Higher CRI means a better quality in that the artificial light is more natural and more likely to spot color discrimination (i.e., to perceive subtle difference in hue). The metal halide bulbs typically have a CRI of about 65 which is deficient in the rendering a colored surface. High CRI in some lighting applications like outdoor sport court lighting is highly desired for televising sports events. The excellent color rendering capability of high mast led flood light enables spectators to see the activity on the field with bright and vivid colors, which allows objects to be distinguished even with subtle color shade differences. High mast led flood light is highly directional by nature. Unlike HID light bulbs that emit light in all directions, LEDs produce directional light with optical efficiencies of 80% to 90%. Typical losses of intensity for metal halide lamps range from 40% to 60% of the light generated. The high optical loss will tend to result in unwanted light pollution such as on-field glare, spill light, uplight, and halo effect light. High mast led flood light, on the other hand, produces a beam pattern that can be more easily varied and controlled to meet light quantity and uniformity specifications and is therefore useful and desirable in the lighting industry.
Low maintenance Cost and environmentally friendly
High mast led flood light are redefining the high power lighting technology. In addition to the aforementioned benefits of longer lifetime, lower operational cost, and better light quality, LED lighting offer many other advantages over traditional light sources. The LED is an instant start-up light source, which will eliminate the initial waiting period for HID lamps to start and restart. The solid-state nature of LED provides for greater resistance to mechanical shocks or vibrations, thereby improving its durability significantly. LED lights are fully dimmable without color variation. A specific light level can be obtained through the operation of changing luminance or brightness of an LED lamp. Moreover, metal halide bulbs that generate significant amounts of short wave ultraviolet light (UV) which can be dangerous to humans, LED. In contrast, an LED luminaire emits virtually no ultraviolet light and no infrared radiation. LEDs contain no mercury or any other hazardous materials and are therefore environmentally friendly.
