#LED VS HALOGEN SERIES#

The introduction of LEDs disrupted this relationship. Wattage is no longer a relevant measure of brightness. The higher a bulb’s wattage, the brighter it would be. In the past, wattage and brightness were directly correlated. So how do these differences play out when it comes to brightness? Sadly, it isn’t a straightforward comparison. These photons then interact with the other materials used in the LED and the current running through it to give off visible light! And that’s LED tech in a nutshell. The extra energy released as electrons changes their state causes photons to be emitted. At the heart of the diode is a p-n junction, of which electrons jump across and, in the process, change their state. The LED, or light-emitting diode, is a semiconductor that controls the amount of electricity that flows through it. If you’ve ever wondered how exactly an LED gives light, read on for a short, sweet, and technical overview. The technology is more advanced and uses electronic chips installed at the base of the bulb. An LED functions as a computer, whereby it has a binary on and off state. On the other hand, an LED works electronically. This has dramatically increased the bulb’s lifespan, giving up to 2000 – 4000 more hours.

Introducing the halogen gas in proximity to the tungsten filament, recycled some tungsten back to the filament, and prevented this carbon buildup. This significantly reduced the lifespan of the bulb. In the process, a carbon buildup was deposited on the bulb’s casing. In an incandescent, the filament heated up so much that the metal disintegrated throughout the bulb’s lifespan.

This gas helps to improve efficiency in a series of ways. Specifically, a halogen bulb has compressed halogen gas in a capsule within the bulb’s body. These bulbs have a tungsten filament that heats up when current is passed through it and becomes white-hot, emitting heat and light. Let’s look at the fundamental differences between a halogen and an LED bulb.Īrguably, a halogen bulb is a more efficient replacement for the old incandescents. How Do Halogen Bulbs Work Compared To LED? This means that LEDs emit much more light using much less energy. LEDs have a lumen per watt ratio of 80-100 lm/W, compared to 16-24 lm/W for halogens.

Halogen bulbs consume more power, heat up quickly compared to LEDs, and give off a fixed color temperature. Traditional incandescent bulbs have been phased out across the globe, attention has turned to their successors: halogens.Īfter brightening our homes for the last 60 years, are halogen bulbs next to be eliminated? You swear there’s something about halogen bulbs that always draw you to them.
