OSRAM SharXS HTI 300W Arc Lamp

The OSRAM SharXS HTI 300W/D5/65 is a high-intensity discharge lamp designed for professional stage, architectural and event lighting. It delivers 22000 lumens at a 6500K daylight colour temperature with a colour rendering index of 85. The compact single-ended arc design suits automated fixtures requiring high output and crisp white light. Rated life is 750 hours.

Check Fixture Compatibility Before Ordering

Verify that your fixture accepts a 300W metal halide arc lamp with the correct base and physical dimensions for the SharXS series. Ensure the ballast or power supply is rated for 300W HID operation and can provide the necessary ignition voltage. Confirm the fixture’s thermal management can handle continuous 300W dissipation. This lamp is not for standard household sockets or low-voltage systems.

Sustained Output Over 750-Hour Life

Under continuous operation the lamp maintains its 6500K colour point and 22000 lumen output for the rated 750 hours. The arc tube stabilises quickly after strike and resists colour shift during long shows or architectural installations. Performance remains consistent across the 5600K to 7800K range specified for the HTI family. Degradation follows the rated life curve without sudden drop-off.
