For example, the traditional 50W dichroic halogen downlight is only 12V AC but draws 4.167 Ampres. An average LED light uses 8 watts of power, while halogen lights average about 90 watts. LED lights are even more economical with around 85% less power consumption than halogen lamps. The bulb lights up when electricity reaches the filament, heating up the tungsten which begins to glow. LED lights also have a clear advantage in terms of durability. LED power consumption: 49 kWh → 7.35 $ Halogen power consumption: 294 kWh → 44.1 $ Incandescent lamp power consumption: 359 kWh → 53.85 $ The comparison shows the big difference in power consumption between conventional light sources and modern LED lighting. Halogen light bulbs have a luminous efficiency of only 2% – 4%. From the factory it’s equipped with HID low beams, and halogen high beams. Power consumption is the lowest compared to all other lighting technologies—80 percent less than incandescent bulbs and 75 percent less than halogen bulbs. A 40-watt equivalent LED bulb consumes only 6 to 8.5 watts. CFL vs Halogen vs LED Making choices in a changing lighting market Now that incandescent light bulbs belong to the history books, building owners and city officials must choose between compact fluorescent (CFL) , halogen and light-emitting diode (LED) lamps to illuminate built and natural environments. CFL vs Halogen vs LED Making choices in a changing lighting market Now that incandescent light bulbs belong to the history books, building owners and city officials must choose between compact fluorescent (CFL) , halogen and light-emitting diode (LED) lamps to illuminate built and natural environments. Compared to traditional incandescents, energy-efficient lightbulbs such as halogen incandescents, compact fluorescent lamps (CFLs), and light emitting diodes (LEDs) have the following advantages: Typically use about 25%-80% less energy than traditional … Inside the bulb is a filament made out of tungsten and halogen gas. This makes xenon lights more efficient than halogen. LED vs. Halogen vs. Xenon headlights HID lamps, which require less power to operate, actually output a brighter light. The Light intensity is quite weak for the halogen and HID, while the LED bulbs have a very tightly concentrated, focused beam right near the center, with a strong curved beam emanating from the center. That's more than 12X as much! LEDs require higher initial investment but produce greater energy returns over time. This movement of electronics through a semi-conductor emits photons, resulting in light. They can last up to 50,000 hours—42 times longer than incandescent bulbs and 13 times longer than halogen bulbs. Therefore, the power of the LED light is proportional to voltage and/or current such that a device may have a low voltage but may still draw a very high current and have high power consumption. Most halogen headlamps produce a colour temperature between approximately 3200K and 5000K. Unlike halogens that have a filament, LEDs operate by transferring current through a semi-conductor. They will last between 15,000 – 50,000 hours. Drawing only about 35 watts of power, they generally are good for about 2000 hours of life. In this case, I’ve swapped one of the halogen bulbs for a LED bulb. A bulb’s ability to emit light relative to its power draw is referred to as its luminous efficiency. With all of us on an energy-saving mission to reduce our household running costs as well as reduce the impact on the environment, it can be difficult to know what to do to save electricity. As mentioned earlier, LEDs are far more efficient than halogen lights. The shatterproof bulbs are shock resistant and have no brittle filaments.
