Product updated on 2019-08-28, SBX Parts - SBX:LED:H11F2, H11 F2 LED headlight bulb kit, Operate on 9 to 32 volts, 6000 lumens per bulb, 23mm fan design for maximum vehicle fitment. Same design as Supernova V.4 or X1 series LED headlight bulbs. 1 year warranty, Canbus interface kits are available., The new intellegent series F2 LED headlights have a 95% fitment rate making installation easier. They also feature an improved beam pattern and automtic temperature controller for stable operation. Cutting-Edge LED Chip Technology: We challenge you to find another bulb on the market that produces as much light as the F2 series while still retaining a perfect beam pattern! Thermal Management: Our F2 series LED Headlights are built from the highest quality 6063 aluminum material originally designed for aircraft and space craft applications. This material has amazing heat dissipation qualities as well as is 100% corrosion resistant in automotive applications. On the bottom of the heat sink lies a high-speed double ball bearing micro-fan that is fully submersible and waterproof! If the fan stops working, the sophisticated thermal management system inside the bulb will dim the headlight until it is safe to use. Compact Design: Most LED headlight bulbs that use a fan-based active cooling system are known for not being small or easy to fit inside headlight housings with a dust cover. The F2 Series is designed to be as compact as possible. The mounting depth is 20-25mm on most bulb variants, low profile enough to fit even the most demanding of spaces! And the heat sink / fan diameter is only 39mm! The LED driver on this bulb is larger than the previous generation, but it is still the right size to fit inside most headlight housings comfortably.
