The "Third Gen" HIR2(9012) incorporates a
burner based on the latest version of high-tech H7 architecture. It has a
high-precision filament coil, 5-axis focused and positioned within the
burner by filament supports configured to leave a metal-free zone around
the filament. The thermal image comparison you see on this page shows
how the new design gives vastly improved control over unwanted
reflections of the filament from the bulb wall and filament supports.
This greatly improves beam focus and reduces shadows and glare light
within the beam. The tubular bulb gives excellent control of stray
light, and it's made of low-distortion quartz with a new
infrared-reflective coating with maximized optical clarity. The fill gas
has been newly formulated to give the HIR2/9012 bulb's characteristic
extremely high light output with very long life.
The "Third Gen" bulb has the highest luminance of any HIR2 (9012) ever made (30 Mcd/m2) giving the driver a significant increase in beam punch, boosting the
ability to see what must be seen at night and in bad weather in time to
avoid a collision. Light quality is bright white, with an excellent
color temperature of 3450K.
A rated lifespan (Tc) that is 40%
longer than previous designs, making this not only the brightest and
best but also the most cost-effective HIR2 (9012) bulb ever made.
This 55-watt bulb is US DOT compliant, with a nominal output of 1875 lumen at 13.2 volts.
This new Philips bulb is physically, electrically, optically, and
legally compatible with all previous 9012 (HIR2) bulbs, so it can be
used for all the same design-specification, replacement, and upgrade
applications. It can replace the 9006 (HB4) for special-service use;
such a retrofit requires minor modification to the bulb base itself. No modification to the vehicle is needed.
