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

When looking for an easy option for better-performing headlights for your vehicle our STEDI Copper Head conversion kits are a simple Plug & Play upgrade that is as simple as changing over a factory globe. 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 lead the market. We’ve put lots of work into perfecting the beam geometry to ensure that our kits won’t cause glare and cause unwanted light scatter. We back this up with a 30-day money-back guarantee. 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 installation are also much wider. Our all-new HB4 (9006) Copper-Head™ LED Headlight Kit is designed for vehicles that 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 compatibilities.
