Halogen lights have two different functions-dimming and bright. These headlights have light bulbs with either a single or a couple of filaments. Comparison table HALOGEN HID LED MAIN COMPONENT Halogen gas Xenon gas Light emitting diodes BRIGHTNESS Low High High LONGEVITY (IN HOURS) 450 - 1 000 2 000 - 8 000 10 000 - 50 000 LIGHTING DIRECTION Omni-directional Directional Directional OUTPUT LIGHT COLOR Warm white Cool bright blue-white White GLARE Not strong Strong Not strong ENERGY EFFICIENCY Low Average High HEAT EMISSION High High Low Halogen Headlights The following guide will help you determine which is the best types of headlights bulbs for your vehicle. Faulty headlights pose a safety hazard to yourself and other drivers and are also illegal. When you buy headlights for your car you want to ensure they will illuminate the road ahead, and also navigate your way during lousy weather. However, one type is better due to the way they are made and the materials used. CONS: Distance not quite as good as its HID counterpart.LED and HID headlights are both effective and do the job you pay for.Although HID still has the 1 up on LED driving light in terms of peak beam distance the LED driving lights produced today are achieving outstanding lux distance performance. Typically LEDs are rated for 50,000 hours, which is x10 that of HID. It is said that one would require 600 watts of halogen lights to produce the equivalent light volume of a 200 watt LED. As can be seen in the comparison image, the light output is far brighter and superior to all of its counterparts. LED’s strength lie within its near instant light, daylight white light temperature and its ultra-low energy consumption. They draw very little power and are extremely resistant to vibrations. Instead, light is produced by excited electrons inside the LED wafer chip. From LED light Bars to Spot lights, to DRLs of all shapes and sizes. The small form factor of the LED brings with it excellent versatility in design. Whilst LED isn’t a brand new concept, it certainly has become the bench mark. PROS: Excellent distance - White/blue (6000k) light temperature - efficient compared to halogen & LED.CONS: Takes a few seconds to reach full light output – Dark spots in light pattern – Very focused light.The most common drawback of HID technology is that it requires 5 to 7 seconds to reach its full operating capacity when first switched on. HID’s are easily identifiable by their white/blue/purple light output, and are commonly found in the factory headlights of leading German automotive manufacturers. Since the globe have no filament, the life expectancy of a HID globe is usually around 3000+ hours. Unlike halogen, HID lights produce a pulse of electrical charge brought about by its ballast. In fact HID (also known as Xenon) produce 3 times the light output of halogens of equal wattage. Whilst HID driving lights have been around since the early 1990’s, they are far superior in light output and luminous efficiency when directly compared to halogens, and a slight higher luminous efficiency when compared to LED. High Intensity Discharge (HID) Driving Lights.
