10 W 12 V G4 Halogen Bulb

This 10 watt 12 volt G4 base halogen bulb delivers 140 lumens at a warm 3000K colour temperature. It is rated for 2000 hours of life and offers a colour rendering index of 100 for accurate colour reproduction. The compact quartz capsule measures 1.25 inches in overall length. It suits residential lamps, desk lights, hanging fixtures and specialised equipment such as microscopes or projectors.

Upgrade From Lower Output Halogen

The bulb replaces dimmer halogen capsules in existing 12 V G4 sockets where brighter, whiter light is required. The jump is worth it when the current lamp produces insufficient lumens for task lighting or detailed work. It also serves as a direct substitute for expired bulbs in medical, ophthalmic or microfilm devices that demand high CRI output. Buyers seeking LED longevity or lower heat should consider alternative technologies instead.

Check Fixture Voltage And Socket

Verify that the fixture supplies 12 volts and accepts a G4 bi-pin base before ordering. Confirm the 1.25 inch capsule length fits within the lamp housing without touching the glass or shade. Ensure the power supply or transformer can handle the 10 watt load per bulb. This bulb is not compatible with mains voltage sockets or dimmers not rated for halogen loads.

Questions about this item

What fixture dimensions suit the 1.25 inch overall length and G4 base?

The bulb measures 1.25 inches end to end and uses a G4 bi-pin base, so it fits low-voltage sockets in desk lamps, pendant lights, microscopes and similar compact fixtures.

What is the correct 12 volt power source and the handling step installers often skip?

Connect the bulb to a 12 volt AC or DC supply rated for at least 10 watts, and avoid touching the quartz envelope with bare fingers because skin oils create hot spots that shorten the 2000 hour life.

When should the bulb be replaced and what indicates end of life?

Plan replacement around 2000 hours of use; the filament will fail and light output drops from the rated 140 lumens at 3000K with a CRI of 100.
