![]() Known for its high-quality products, the X-treme Vision is its leading halogen bulb product. Philips is also an OEM with a big name internationally. Philips X-TremeVision High-Performance Halogen Headlights The prices and specifications for both products are based on the H7 size light bulb. The products are from two of the leading international brands and are fairly indicative of the market. To provide you with some references for halogen bulbs, we’ve listed two products that fall into the high-performance headlight bulb category. This simplicity helps keep its cost low.įor all the amazing benefits of HID and LED bulbs, halogens get the job done for a fraction of the price. If the bulb stops working, it’s because the filament is damaged. Unlike HID and LED setups, there are no fancy electronics required to keep the bulbs happy it’s just straight wires connecting everything. Halogen’s redeeming features are its simplicity and its cost. This is one of the reasons LED and HID bulbs can be much brighter than halogens, as they are more than 10 times more efficient than halogens. As such, any improvements to a light bulb’s luminous efficiency allow for a brighter light. This rating is based on the amount of power the light draws. Halogen light bulbs have only 2% – 4% luminous efficiency.įor many countries, the power of their headlamps is limited from a legal perspective. That looks at the amount of power emitted as light compared to the amount of electrical power drawn. One problem with this is that a lot of their energy is heating.Ī bulb’s ability to emit light relative to its power draw is referred to as its luminous efficiency. ![]() This is why halogen light bulbs are so hot to the touch. When a current is passed through the filament, it heats up, and it starts to emit light because it gets white-hot. ![]() ![]() Alternatively, the bulbs’ brightness can be increased for the same lifespan. The added halogen gas allows for evaporated tungsten to be redeposited onto the filament, allowing for longer-lasting bulbs. Most conventional light bulbs just make use of argon. Halogen lights are a form of incandescent light bulb making use of a tungsten filament with a small amount of halogen gas. ![]()
