Lucalox XO Superlife Tubular Clear

Product information

Lucalox™ XO Superlife lamps comprise a sodium discharge system operating at a high pressure within a ceramic arc tube which is mounted in an outer glass bulb. These lamps offer outstanding luminous efficacy, lumen maintenance thus reducing energy and maintenance costs. All lamps have two arc tubes. The second arc tube will instantly light after a momentary power interruption. Arc tubes are Monolithic construction for 50-400W lamps.

Application areas

These lamps can operate in outdoor and industrial applications, such as bridges, tunnels, roadway, floodlighting, industrial interior illumination and any “hard to reach” areas. Easy replacement of standard HPS lamps, fits standard HPS sockets – no new wiring, ballast or fixture are required.


Dual arc tube
GE Lucalox™ XO Superlife lamps feature a dual arc tube design that provides extra long life. The second arc tube also assures that critical lighting applications will instantly relight, even after momentary power outages.

Longest life for reduced maintenance
The twin arc tubes provide up to 60,000 hours life, up to 70% longer than XO HPS lamps. This longer rated life reduces relamping costs by significantly increasing the maintenance interval.

Continous light after power interruption.
The second tube provides light instantly after momentary power interruption increasing to full light output in less than three minutes.
