Compact low-voltage halogen lamp
The OSRAM SYLVANIA 64427 is a 20 watt 12 volt GY6.35 bi-pin halogen bulb built for accent and task lighting. Its axial filament and UV-control quartz capsule produce 300 lumens at 2800K with a colour rendering index of 100. The lamp is approved for open luminaires under IEC 60598-1 and contains no mercury.
Replaces earlier bi-pin capsules
Swapping an older low-voltage halogen capsule for this STARLITE model adds a UV-filter that cuts UV-B and UV-C radiation by 90 percent compared to regular quartz. The dichroic reflector redirects up to 66 percent of heat out of the light beam, so the upgrade is worthwhile when fixtures run hot or when shielding is impractical. Rated life reaches 2000 hours at the stated voltage.
Fits GY6.35 sockets in 12 V systems
The GY6.35 base plugs directly into compatible low-voltage sockets without an external ballast. Because the capsule is low-pressure and cleared for use without additional shielding, it frees designers from specifying protective covers in many residential, commercial and industrial fixtures. Ensure the supply delivers a stable 12 volts to achieve the rated output and lifetime.

Questions about this item
Does the GY6.35 bi-pin base fit a 6.35 mm pin-spacing socket?
Yes, the GY6.35 base has pins spaced 6.35 mm apart and fits matching low-voltage bi-pin sockets.
What is the correct way to handle the quartz capsule during installation?
Wear clean gloves or use a cloth to avoid finger oils on the UV-control quartz; oils create hot spots that shorten the 2000-hour rated life.
When should I replace the bulb based on its rated lifespan?
Plan replacement around 2000 hours of use; the axial filament design maintains 300 lumen output and 2800K colour until end of life.
