If you’re wondering if you should upgrade your headlights to HIDs or LEDs then this article may help you decide which is the better choice.
HID which stands for “High-Intensity Discharge” produce light by creating an electric arc between two electrodes in a gas-filled (usually xenon) chamber. The arc excites the gas, generating a bright, intense light.
LED which stands for “Light-Emitting Diode” use semiconductor diodes that emit light when an electric current passes through them. They rely on solid-state technology, meaning no gas or filament is involved.
Both are popular lighting technologies used in modern vehicles. Most vehicles are now coming with LED headlights due to their flexibility of headlight designs they can be incorporated into. Where HIDs can only be in a round glass sphere LEDs can be made into multiple small reflectors and projectors allowing for a wide range of visual appeal.
Brightness
HID: Typically very bright, often producing 3,000 to 4,000 lumens per bulb, depending on the ballast wattage.
LED: Also very bright, with outputs ranging from 3,000 to 6,000 lumens or more, depending on the design. Some sellers claim more than 10,000 lumens but that is impossible and a pure marketing scheme.
NOTE: Even though LED bulbs can “technically” produce more lumens HID bulbs will still produce a brighter beam pattern when used in a headlight application due to the optics of the headlight favoring the HID bulbs design.
Energy Efficiency
HID: Less energy-efficient than LEDs, requiring around 35 watts per bulb when using the standard 35W HID ballasts. Can also be upgraded to 50-55W ballasts for even more power.
LED: More energy-efficient, typically using 20-40 watts per bulb. LEDs convert more energy into light rather than heat, making them a greener option.
Lifespan
HID: Lasts around 2,000 to 5,000 hours. While durable, they degrade and get more dim over time as the gas and electrodes wear out.
LED: Much longer lifespan, often rated for 20,000 to 50,000 hours. LEDs are more resistant to vibration and wear since they lack fragile components.
Startup Time
HID: Takes 10-20 seconds to reach full brightness as the gas needs time to heat up and stabilize the arc.
LED: Instant-on, providing full brightness immediately when powered.
Heat Output
HID: Produces significant heat due to the arc and gas reaction, though most of it is directed forward.
LED: Runs cooler than HID, though they still generate some heat that requires cooling systems (like heatsinks or fans) to manage.
Cost
HID: Generally cheaper upfront but may require more maintenance (e.g., replacing bulbs or ballasts) over time.
LED: More expensive initially, but their longevity and efficiency can make them more cost-effective in the long run.
Color Temperature
HID: Typically ranges from 4,300K (warm white) to 6,000K (cool white), with some kits going higher for a more stylized look.
LED: Offers a broader range, from 3,000K (warm yellow) to 6,500K+ (cool blue), giving more customization options.
Installation
HID: Requires a ballast and sometimes additional wiring, making installation more complex. Retrofits may need adjustments to avoid glare or improper beam patterns.
LED: Often plug-and-play for newer models, though some require external drivers or resistors. Proper alignment is key to avoid blinding other drivers.
Durability
HID: More sensitive to vibrations and shocks due to the glass bulb and gas components.
LED: More robust since they’re solid-state, with no moving parts or fragile filaments.
Which is Better?
HID is great for drivers who want bright, cost-effective lighting and don’t mind a slight warm-up time or occasional maintenance.
LED is ideal for those prioritizing energy efficiency, instant light, and a longer lifespan, especially in rugged conditions.
It often comes down to your vehicle’s compatibility, budget, and personal preference for light quality. Always ensure the bulbs match your headlight housing for optimal performance and road legality!
