Diode Dynamics H11 LED HP48: This bulb is designed with 48 Epistar 3014 LED chips. Thanks to the cap on the top, the light from this High Power Bulb is shined backwards and away from the bulb, not straight out. This means the output is excellent, because it uses the vehicle's housing completely, which then shines the light much more uniformly. XP80: Each of the four sides of this bulb contains three 5W-rated chips, and the top is fitted with four more, under a projector lens. This is the brightest self-contained automotive LED bulb on the market, and is housed in an aluminum casing with a textured finish for maximum heatsinking properties.
