Stedi H4 Copper Head LED Bulbs (Pair) LEDCONV-H4-CH

BUILT TO LAST

Theyve moved away from active cooling (fan kits) and adopted passive cooling. Passive cooling not only substantially increases reliability, but the flexible cooling belts of the Copper Heads offer the ability to retain the use of the factory dust caps maintaining the water & dust resistance of the headlight housing. With lower profile than that of a fan cooled kit, compatibility and ease of install is also much wider.

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 compatibility.

KEY LIGHTING BENEFITS

• Top Bin Philips Lumileds Luxeon ZES LED | Theyve independently verified the authenticity of the Philips Lumileds used. The undomed nature of the ZES provide better optical control with minimal scatter.

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

• OEM matching light distribution through exact positioning of the LED emitters to optimise the vehicles reflector design as the OEM intended.

• Instant Full Beam without any warm up time.

TECHNOLOGY

• CAN-Bus cancellation built in
• Unlike other platforms on the market, the Copper Heads LED Kit will not discolour or tarnish your vehicles headlamp reflector or lenses.
• Electri
