STEDI HB4 (9006) Copper Head LED Bulbs (Pair)

Our all-new H4 Copper-Head™ LED Headlight Kit is designed for vehicles that have enclosed headlight bulbs that prevent our fanned Night Pilot kit from being installed. We’ve tested a nauseating amount of different “no fan” LEDs and ultimately rested on our Copper Heads™ for its excellent light distribution, brightness & durability.

MATERIAL & THERMAL MANAGEMENT - Staying cool is the end-all and be-all in the world of LED.  Well executed thermal management means higher drive current leading to higher light volume.

• Six 100% Pure Copper(Cu) belts allow maximum thermal conductivity.  The thermoelectrically separated copper substrates allow heat to transfer to the substrate efficiently and quickly.

• American made Down Corning® thermal paste to increase conductivity to 6063 aluminium tower.  

• No fan means modern vehicles which have rigid dust covers or fully enclosed headlights bulbs can upgrade to LED without modifying the dust cap or worse leaving them off altogether.

• Smaller driver footprint for tight applications.

• Near identical footprint to stand halogen bulb ensure 100 compatibilities.

KEY LIGHTING BENEFITS

• Top Bin Philips© Lumileds Luxeon ZES® LED | We’ve independently verified the authenticity of the Philips© Lumileds used.  The undomed nature of the ZES® provides better optical control with minimal scatter.

• CCT 5700K means colours sync with our auxiliary LED driving lights.

• OEM matching light distribution through the exact positioning of the LED emitters to optimize the vehicle's reflector design as the OEM intended.

• Instant Full Beam without any warm-up time.

TECHNOLOGY
