Product Overview

The Sylvania 58766 500Q/CL/MC (EVR) is a 500‑watt, 120‑volt halogen specialty lamp delivering 10,450 initial lumens at 3000K with CRI 100. It features an E11 miniature candelabra screw base and a clear T4 bulb, making it ideal for projection systems, photo‑optic equipment, and specialty medical/dental lighting where high output, accurate color rendering, and long life are critical.

With a 2,000‑hour rated life, this lamp significantly reduces maintenance frequency compared to shorter‑life halogen lamps. The universal burn position allows flexible installation in any orientation, while the 3000K natural white color temperature provides a warm, pleasing light suitable for professional imaging applications.

Technical Specifications

Dimensions

Applications

• Projection systems – slide projectors, overhead projectors, LCD/DLP projectors
• Medical equipment – endoscopy, dental lighting, surgical headlamps
• Microscopy – illumination for biological and industrial microscopes
• Photo‑optic equipment – film scanners, enlargers, specialty imaging
• Stage and studio lighting – small fixtures requiring E11 base

Compatibility & Replacement

Fixture type: Designed for professional photo‑optic and projection equipment requiring an E11 miniature candelabra screw base and 500W/120V halogen lamps. Common in medical endoscopy, dental curing lights, microscopy, and OEM projection systems.

Base: E11 – miniature candelabra screw base, smaller than standard E26. Confirm your fixture uses E11 lampholders.

Ballast: No ballast required – operates directly on 120V mains power (some equipment may use transformers).

Before ordering, confirm:

• ANSI code – EVR: Verify your equipment specifies EVR or equivalent 500W/120V E11 halogen lamp.
• Voltage – 120V: Verify fixture supply voltage is 120V.
• Base type – E11: Physically inspect your existing lamp or lampholder to confirm E11 base.
• Physical dimensions: Verify your fixture accepts a T4 bulb with 3.75‑inch overall length.
• Fixture wattage rating: Ensure equipment is rated for at least 500W.
• Burn position – universal: Works in any orientation, but always follow OEM guidelines.

Safety & Handling Notes

• High pressure warning – face shield required: Halogen lamps operate under high internal pressure. Always wear a face shield and protective gloves during handling and installation. Lamp burst can cause serious injury.
• No bare hands: Never touch the quartz envelope with bare skin. Oils cause hot spots leading to premature failure or lamp burst. Use clean gloves or a lint‑free cloth.
• Do not exceed rated voltage: Operating above 120V dramatically shortens lamp life. Verify supply voltage before installing.
• Burn position – universal: This lamp is rated for universal operation, but always follow your equipment manufacturer’s guidelines.
• Extreme heat and UV output: Use only in approved enclosed luminaires with appropriate UV filtering.
• Allow complete cool‑down before handling: Allow lamp to cool completely before relamping. Do not touch immediately after switching off.
• Follow your equipment manufacturer's service documentation for lamp replacement procedures.
