Fan vs Fanless Led Headlights

Many car owners upgrade their factory headlights by swapping halogen bulbs to LED. These bulbs provide brighter lighting, form right beam in both projector and reflector headlights and last much longer, than regular halogen bulbs. The only drawback of the LED bulbs is excessive heat they produce. Hence, such bulbs come equipped with a cooling unit that allows reducing temperature. Modern LED bulbs for high and low beam upgrade feature fan or fanless construction. So, which bulbs are better? Let us consider pros and cons of both constructions, so that you could determine, which ones to consider for your vehicle.

LED headlight bulbs: operation temperature

To provide light output that is sufficient for forming quality light beam, LEDs use the light emitting diode itself and use a built-in microprocessor. Combination of these two elements produces excess heat that has to be eliminated to prevent melting. Yes, LED bulb features lower resistance, than halogen bulbs, yet it is the processor and powerful diode, that produce heat. So, such bulbs require a powerful cooling unit to operate.

Fan vs Fanless LEDs: comparison & explanation

Leds that come equipped with fan use active cooling. It means that fan rotates and reduces heat. Yet some bulbs with active cooling units are made too big and cannot be normally fitted into the headlight assembly. Yet, there are slim fans that do not require a lot of space in a headlight.

LEDs with passive cooling, or fanless, feature either braided heat sinks, or get cooled by means of internal drivers. Internal driver cooling method is third generation of LED heat elimination. Fanless bulbs feature slimer filament, compared to the LEDs equipped with cooling fan.

Fan vs Fanless LED Bulbs: Pros & Cons

#FANFANLESS
1Quick heat eliminationSome filaments with fans are too large
2Slim fanless LEDs don’t require a lot of placeFanless LED bulbs with braided heat sinks require checking the heat sinks condition from time to time
3Do not require extra spaceNoiseless operation
4Do not come with external cooling unitsLonger lifespan,compared to fan LEDs
5Fan sometimes creates noiseSlim filament in quality LEDs
6If the headlights are not sealed properly, fans may gather dustThermal resistance to drops
7Fan may consume additional powerFanless leds do not require extra maintenance

Featured Cars, Trucks & SUVs

Hikari LED bulbs are available for the majority of cars, trucks and SUVs that are popular in the U.S. These bulbs are significantly brighter, than the regular halogen or incandescent bulbs, they last longer and due to their construction easily withstand vibration, moisture, dust and temperature changes. The cooling units and the shape of the bulbs are slin enough to fit the majority of the factory duct covers. You can check the LED bulbs for your vehicle to determine the bulb size and part numbers quickly.
