Product Identity
The SYLVANIA 58672 is a 12 volt bi-pin halogen capsule rated at 35 watts. It delivers 580 lumens at a warm 2900K colour temperature with a CRI of 100. The lamp uses UV-stop quartz that cuts UV-B and UV-C output by 90 percent and is designed for open fixtures without additional shielding.
Who It Suits
This bulb fits low-voltage bi-pin sockets in accent, task and display lighting where high colour fidelity and a compact axial filament are required. Buyers who need a mains-voltage lamp or a different base type should select another product. The 2000-hour rated life suits installations where occasional replacement is acceptable.
Deciding Specification
The critical figure is the 12 volt bi-pin base; the lamp will only operate on a compatible low-voltage transformer and socket. Verify that your fixture supplies 12 volts and accepts a bi-pin capsule before purchasing.

Questions about this item
Does the 12 V bi-pin base carry a current limit that caps the 35 W draw?
The lamp is rated for 35 W at 12 V, so the base and capsule are designed to handle that power level without an additional current-limiting feature.
What socket spacing does the G4 bi-pin base need to fit?
The G4 bi-pin base has 4 mm pin spacing and requires a matching G4 socket; verify the fixture accepts a T4 quartz capsule of this length.
How is the bulb installed, and what handling step is often missed?
Insert the pins straight into the G4 socket until seated; avoid touching the quartz capsule with bare fingers because oils can cause hot spots and shorten the 2000-hour life.
