PROPER COLOR: XTR LED bulbs are engineered for optimal lighting performance over the long haul. Premium emitters are accurately color-binned for true white, true amber, and true red light and produce the right luminous flux for the intended application - the intensity ratio of your lamps is preserved for all lighting functions.
EFFICACY:The market is flooded with gimmicky LED bulbs with inflated lumen numbers (that are usually too long to fit into the intended lamp) but all the lumens in the world won’t do you any good if the light isn’t distributed properly. Automotive turn signal bulbs have to spread their light through a complex matrix of vertical and horizontal angles so that everyone else on the road gets their intended message correctly — no matter if they're up high in a semi-truck, down low in a sports car, right behind you or two lanes over. To get it right takes the kind of careful engineering, which was done on the XTR LED bulbs. We've introduced a new unitized ICF (Inverse Conic Focus) integrator which gives these bulbs a spherical light output - you get the right amounts of light in the right places no matter whether your lamps have lens optics, reflector optics, or both.
PROPER THERMAL MANAGEMENT:Precision-machined aluminum bodies provide excellent thermal mass so the light output doesn't "droop" with prolonged operation or in high ambient temperatures. All in all, XTR LED bulbs are the smart, state-of-the-art choice for LED bulbs that just plain work.
