![]() ![]() Color TemperatureĬolor temperature is measured on the kelvin scale (K). That means that you’ll get a much higher brightness level from LEDs than halogens-even if you use a less-powerful bulb.įor example, a 15-watt LED bulb will be as bright as a 85-watt halogen bulb. Halogen lights emit about 16-24 lumens per watt, whereas LED lights emit about 80-100 lumens per watt. This makes them a much more economical option for overall costs in the LED vs. On the other hand, despite being slightly more expensive, LED light bulbs last longer consume far less electricity. 80 percent of the energy they consume is converted to heat, and only 20 percent is emitted as light. While halogen lights are cheaper to buy, they burn out much faster than LED lights. Why? Because of these differences… Economical You have probably noticed that there are fewer halogen lights available nowadays. Differences between LED and Halogen Lights This is where LEDs or light-emitting diodes get their name. The diode is made of two different types of semiconductor material, and when an electrical current is applied, the diode emits light. A LED is a semiconductor light that uses a diode to convert electrical energy into light. On the other hand, a LED works completely different. Although halogen bulbs are brighter, they also produce a lot heat! The gas prolongs the bulb’s life and allows it’s tungsten filament to burn at a higher temperature than a regular incandescent light bulb. LED?Ī Halogen light is a type of incandescent light that is filled with halogen gas. In this article, I’ll explain the differences between halogen and LED lighting so that you can make an informed decision when choosing which type of light to use. ![]() ![]() Halogen bulbs can be dimmed, but occasionally they should be operated at full light output to retain long life.Choosing a light bulb used to be a simple task with only two things to consider What shape and how many watts? Well, technology in lighting has advanced significantly in recent years and LED has become a whole new category of light source.In addition, the bulbs produce ultraviolet radiation that may be harmful if light is not first absorbed or filtered by a glass shield. Halogen bi-pin and J bulbs can burst, and therefore, should be used in a fully enclosed fixture to provide shielding.Keep combustible materials away from the bulb and avoid touching while in use. The bulbs must be protected by a glass cover in the fixture to prevent potential damage from bulb rupture. do not touch J-type bulbs with bare hands because high temperatures may crack the quartz bulb if it has been etched with oils from hands and fingers. Because of their high operating temperatures and unique bases, thermal control and socket design within the fixture are important. They may be double or single ended and are available in a variety of lengths and wattage. Tube-shaped halogen bulbs (J-type) are made of quartz glass to withstand high operating temperatures. Most halogen bulbs use about one-quarter less energy than the standard incandescent, but recently some halogen lamps have entered the market that use half the energy of standard incandescents. Halogen infrared (IR) bulbs also have a reflective coating to redirect infrared energy back onto the filament to save energy. Halogen bulbs have an inner capsule that contains halogen gas, which extends bulb life. Halogen screw base bulbs fit into the same medium-based sockets as common incandescent bulbs. Halogen bi-pin bulbs only fit into fixtures designed exclusively for their use. Some halogen bulbs have a pin base (bi-pin). Restrict their use to applications where short hours of use are expected, or where there are no other alternatives. ![]() However, halogen bulbs offer significantly lower efficacy and shorter life than fluorescent and LED bulbs. Due to the addition of halogen gas and in some products a coating that reflects infrared energy, halogen incandescent bulbs are somewhat more efficacious (the amount of light produced per unit of input power) than common incandescent bulbs. ![]()
