Technical Specifications

Product Overview

The Ushio 1002247 ELD/K is a precision photo-optic halogen lamp engineered for professional OEM equipment in dental, medical, and projection system applications. At 150 watts and 21V with a 3400K color temperature, this lamp delivers the consistent, high-intensity illumination and accurate color balance required by precision optical instruments — including dental examination lights, surgical illuminators, and specialty projection equipment.

The 40-hour rated life is standard for high-intensity photo-optic lamps of this wattage and voltage class, where maximizing brightness and color accuracy at a specific color temperature takes precedence over extended service life. Always confirm your equipment's required lamp rating before ordering — using an incorrect wattage or voltage will shorten lamp life or damage equipment.

This lamp requires horizontal burn position only and must be installed in an approved enclosed halogen fixture. Confirm your equipment supports this orientation and fixture type before ordering.

Compatible Applications

• Dental lighting — OEM replacement for dental examination and curing light equipment specifying ELD/K or JCR21V-150W lamps.
• Medical and surgical lighting — Precision instruments and examination equipment requiring consistent 3400K photo-optic output.
• Projection systems — Specialty projection equipment using MR16 GX5.3 photo-optic lamps at 21V.

Before Ordering — Verify

• ANSI Code: Confirm the existing lamp or equipment manual specifies ELD/K.
• Voltage: Confirm the equipment transformer output is 21V. Operating above rated voltage dramatically shortens lamp life.
• Wattage: Confirm the equipment is rated for 150W.
• Base Type: Confirm the socket matches GX5.3 Bi-Pin.
• Burn Position: This lamp requires horizontal operation only. Confirm your equipment mounts the lamp in the horizontal position.
• Physical Fit: Confirm 44.5mm MOL and 50.7mm diameter fit within your equipment's lamp housing.

Safety and Handling Guidelines

• Approved Enclosed Fixtures Only: This lamp must be installed in approved enclosed halogen fixtures. Do not use in open or unshielded housings.
• Do not touch the quartz envelope with bare hands. Skin oils cause hot spots leading to premature failure or lamp burst. Use clean gloves or a lint-free cloth. If accidentally touched, clean with isopropyl alcohol before use.
• Do Not Exceed Rated Voltage: Operating above 21V will dramatically shorten lamp life. Verify transformer output before installation.
• Extreme Heat Warning: This lamp operates at very high surface temperatures. Never touch when lit or recently switched off. Keep away from combustible materials.
• Inspect Before Use: Inspect the quartz envelope for cracks or damage before installation. Do not use a damaged lamp.
• Handle with Care: Quartz halogen lamps are sensitive to vibration and mechanical shock during handling and installation.

Compliance

• Verify RoHS compliance status and additional certifications with the Ushio manufacturer specification sheet prior to use in regulated installations.
