Halogen lamps can also operate at a higher temperature than incandescent lamps. So halogens can last up to 2,500 hours while incandescents have an average life of 800-1,200 hours. The flow of electrical current starts the “halogen cycle,” where the particles burning off the tungsten filament are then redeposited back onto the filament by the halogen inside the quartz capsule, allowing for these particles to be “reused.” Reusing the particles gives the lamp a higher luminous efficacy and a longer life than incandescent lamps. This gas is inert and made up of iodine and bromine. The enhancement with halogen lamps is that the filament is enclosed in a quartz capsule filled with halogen gas. Just like with incandescent light bulbs, the electrical current enters the socket and travels up to the tungsten filament, heating up the filament to incandescence. Remember how incandescent light bulbs work? Halogens work very similarly.Įlectrical current flows from the socket and makes contact with the base of the light bulb. Instead we call them a sub-category of incandescent light bulb family. Because halogen lamps are only an enhancement of incandescent technology we don’t classify them as their own lamp family. We classify a light bulb by the technology it uses to produce artificial light. Halogen light bulbs have tungsten filaments housed in a quartz capsule and filled with iodine and bromine gases. Halogen is a type of lighting technology that is essentially an enhanced version of incandescent. Let's briefly define halogen light before we jump in. Understanding how the light bulb produces artificial light helps us (and you) pick out the right bulb for the right application. ![]() Understanding how the light bulb produces artificial light helps us (and you) to troubleshoot when scenarios go haywire.Įxample: Did you know that some halogen and HID lamps look nearly identical? Knowing the differences in technology will help you quickly identify that you have a halogen lamp in a HID socket.Let’s answer those questions and dive into the pros and cons of halogen technology.īut, before we begin, you may be thinking, “So, why do I need to know about technology and how does this knowledge benefit me?” I want to throw out a few advantages of understanding the technology before taking a deeper dive into the technology itself. How do halogen lamps emit artificial light? Where should you use halogen lamps? Where does halogen fit into the lighting industry? Or perhaps you have heard them referred to as the lamps that have a bulb within bulb – similar to a dream within a dream, huh? You may have heard about the light bulbs that are too hot to handle.
