Compatible Sony TV Lamp

This 120 watt replacement lamp fits Sony KL37W1U models and ships with the bulb already mounted in its housing. It is built for owners of those specific televisions who need a direct swap when the original lamp reaches end of life.

Steady brightness over hours

The lamp is designed to maintain consistent output during extended viewing sessions rather than only in short bursts. Quality components and pre-shipment testing aim to reduce early dimming or colour shift that can appear with prolonged use.

Fixed 120 watt power envelope

The television’s ballast supplies a set 120 watts, so the lamp cannot draw more power to increase brightness. Users who need higher lumen output would require a different TV chassis rather than a brighter lamp in the same housing.

How hot does the 120 Watt lamp run during continuous daily use?

The 120 Watt rating defines its power draw; operating temperature will follow the TV's original cooling design for the Sony KL37W1U.

Does the 878439148743 lamp include the housing, or must I reuse the old cage?

The replacement ships as a complete assembly with both the bulb and housing, so no extra parts are required.

Will this 120 Watt lamp fit the original Sony KL37W1U without any adapter?

It is built to OEM requirements and guaranteed 100% compatible with the original equipment.
