Product Overview
This Sylvania single-end quartz halogen lamp is built for photo-optic and projection equipment where a compact, high-output source is required. The DC Bayonet (2-Pin) base and 1.63" light center length are engineered for precise, repeatable positioning within the optical system of the fixture or projector it's designed to replace.
Rated for 2,000 hours at 130V, the 58753 outputs 4,850 lumens at 2950K in a frosted envelope. Because this is an unshielded quartz halogen capsule, it is intended for installation inside equipment that provides its own protective shielding – it is not designed for use as a bare, exposed light source.
Compatible Applications
- Photo-optic, projection, and audio-visual equipment specified for a DC Bayonet (2-Pin) base lamp
- Studio, stage, and specialty equipment calling for the Sylvania 58753 or its 250Q ETB equivalent
- Equipment supplying 130V to the lamp socket
- Enclosed fixtures/equipment that provide their own protective shielding for this lamp type
Before Ordering – Verify
- Confirm supply voltage is 120V – this lamp is not rated for other voltages
- Confirm the equipment provides its own protective shield – this is an unshielded quartz capsule, not a general-purpose bulb
- Confirm DC Bayonet (2-Pin) base and LCL of 1.63" match your equipment's socket and optical alignment
Safety and Handling Guidelines
- A suitable protective shield, screening technique, or both must be used to protect people and surroundings from the possibility of lamp shattering and from possible ultraviolet radiation
- Allow the lamp to cool completely before handling or relamping
- Avoid touching the quartz envelope with bare skin; oils can shorten lamp life – handle with a clean cloth or gloves
- Do not exceed the equipment's rated maximum wattage
- Dispose of in accordance with local regulations for halogen lamps
Compliance
- Mercury-free halogen lamp
- Requires protective shielding in the end-use equipment – not rated for use as an unshielded, exposed light source
