STEDI H4 Copper Head LED Bulbs (Pair)

+207% LIGHT VOLUME

On average most halogen 55W lamps will produce 850 Lumens per lamp, compared to 1,760 Lumens per lamp for our Copper Heads. Our Lumens are not to be confused with the exaggerated numbers by other vendors, our Copper Heads are properly tested inside of a Photometric Sphere. All that brightness is useless without exacting light distribution, and this is where we really where we lead the market. We’ve put lots of work in perfecting the beam geometry to ensure that our kits won’t cause glare and cause unwanted light scatter. We back this up with 30 days money-back guarantee.

BUILT TO LAST

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

THE NITTY
GRITTY.

Our all-new H4 Copper-Head™ LED Headlight kit is designed for vehicles which have the 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 compatibility.

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® provide better optical control with minimal scatter.

• CCT 5700K means colours sync with our 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.
