HID vs LEDHigh intensity discharge lamps are excellent lighting fixtures when you need to illuminate large areas such as in stadiums, gymnasiums, movie theaters, parking lots, and even pathways. They are also perfect for indoor gardening as well as for large indoor aquariums since these lighting fixtures emit huge amounts of ultraviolet radiation needed by both plant and marine life.

 

Practical Applications of HID Lights
Nonetheless, the practical applications are limitless. Smaller versions of the technology have been extensively used in motor vehicles, deep sea diving, mining equipment, as well as in portable lights. Airport runways and tarmacs are lined with HID lights. HID lights are more energy-efficient than a tungsten-halogen light.

 

Concerns on UV Radiation
However, as these lights emit ginormous amounts of UV radiation, prolonged exposure can result in sunburn as well as arc eyes, especially from HID lights that are found in larger environments. Because of this, it may be time to retrofit your HID or HPS light with the correct LED light.

 

Flood LightHID vs. LED Efficiency
While HID systems are known to be generally energy-efficient, when compared to LEDs, they fail quite surprisingly. HID light systems have a measured efficiency rating of not more than 30 lumens per watt while LED systems typically enjoy a remarkable 50 lumens per watt, at the minimum. The measurements have already taken into account the effect of trapped light, protective covers or lenses, operating temperatures, and power supplies in the known source efficiency rating of both HID and LED lights.

 

LED lights also produce a gently sloping lumen depreciation compared to HID lighting systems. Over time LED lights decline gradually whereas HID systems have a steeper decline in their lumen depreciation. This combined higher efficiency and slower lumen depreciation clearly makes the LED lighting systems superbly more energy efficient than HID lighting systems.

 

Retrofitting Your HID with LED
It is without a doubt that LED lights are more efficient than HID lamps and comes with the added benefit of not giving off HID vs LEDultraviolet radiation rendering it safer to use, even after prolonged exposure.

 

There are a variety of LED retrofit kits specifically designed for replacing ceramic metal halide lamps, quartz metal halide lamps, or even high pressure sodium lamps to provide illumination that is as bright as natural sunlight and its harmful UV radiation. The main question most people will be asking is how to choose the correct LED light model to retrofit a particular HID fixture.

 

To retrofit your metal halide type of HID light fixture, you need to compute for the effective lumens of your HID. Multiply the metal halide HID’s mean lumens with the efficiency rating of the fixture. The resulting effective lumens shall serve as your basis for choosing the correct LED retrofit kit. The same process can be used in determining the best LED retrofit kit for a high pressure sodium type of HID. However, you need to multiply the effective lumens (mean lumens x efficiency rating) with a constant of 0.38 as a value for perceived lumens.

 

If you have problems determining which LED retrofit kit will be correct for your HID lighting system, your friendly LED distributor or agent will be more than happy to assist you.
