G4 halogen capsule for 12 V fixtures

The Antique Light Bulb Co. 64258 HLX is a 20 W halogen bulb with a G4 two-pin base designed for 12 V low-voltage systems. It produces 350 lumens with a colour rendering index of 100, making it suitable for accent, task or display lighting where accurate colour is required.

Output and rated life

At 20 watts the lamp delivers 350 luminous flux, providing ample brightness for small enclosed fittings or under-cabinet applications. The rated lifetime is 2000 hours, after which output will decline and replacement should be planned.

Heat and power characteristics

As a halogen capsule it runs hot during normal operation and requires a fixture rated for the heat load. Power draw is a steady 20 W at 12 V with no additional ballast losses, and the bulb operates silently without fan or electronic noise.

Questions about this item

Will this 20 W 12 V G4 bulb overload a vintage low-voltage desk lamp rated for 10 W?

The bulb draws 20 watts at 12 volts, so it exceeds a 10 W fixture rating and could overheat the wiring or transformer.

How do I confirm the 64258 HLX is performing to its 350 lumen spec once installed?

A light meter at the working distance should read roughly 350 lumens; visually, the 100 CRI output will render colours accurately without a green or magenta tint.

Does the single 64258 HLX bulb ship with a G4 socket or any wiring adapters?

Only the T3 halogen capsule with its G4 two-pin base is included; sockets, transformers or leads must be sourced separately.
