Clear Double-Ended Halogen Bulb

This 150 watt halogen lamp delivers 2400 lumens at a warm 2950K colour temperature. It fits fixtures with an R7s recessed single contact base and measures 79 millimetres or 3.11 inches in length. The clear finish suits ceiling fixtures, track lighting and showcase displays in residential or commercial settings.

Check Fixture Voltage and Base Type

Verify that the socket is rated for 120 volts and accepts an R7s double-ended base before ordering. Confirm the fixture can accommodate a 79 millimetre lamp without touching glass or shades. Ensure the circuit and dimmer, if used, support the 150 watt load.

Replaces Standard Incandescent Double-Ended Lamps

The halogen design provides a whiter light and a CRI of 100 compared with typical incandescent bulbs. Rated life is 2000 hours, reducing relamp frequency in high-use fixtures. The upgrade is worthwhile where colour accuracy and brighter output are priorities over maximum energy savings.
