Ushio AL-0950 MFI Solarc arc 24W MR11

Solarc arc lamp for LB24M fixtures

The Ushio AL-0950 MFI Solarc is a 24W metal-halide arc lamp built as a direct replacement for LB24M housings. It produces bright, daylight-quality output from a compact MR11 envelope while drawing only 0.40A. The lamp suits medical endoscopes, industrial fiberscopes, bicycle lights, dive lamps and rugged portable flashlights. Its Solarc technology delivers roughly three times the efficacy of comparable halogen sources.

Steady output under continuous duty

Because the arc stabilises quickly, the lamp maintains consistent colour and intensity during long procedures or extended night rides without the drift seen in short-burst sources. The rugged arc tube resists vibration and shock, so output stays reliable when the fixture moves through rough terrain or clinical handling. Minimal power draw means less heat builds up in sealed housings, helping the surrounding optics and electronics stay within thermal limits over hours of use.

Check voltage and ballast compatibility

Verify that your LB24M or equivalent fixture supplies the correct striking and sustaining voltage for a 24W metal-halide arc source. Confirm the ballast or driver is rated for 0.40A operation and that the MR11 base seats securely in the existing socket. Ensure the housing can vent the modest heat generated so the lamp reaches full brightness and achieves its rated service life.
