Product Description
MR16 halogen reflector lamp (ANSI DED) for precision optical illumination: microscopy, lab/analysis, UV curing, fiber illumination, and surgical/dental overhead.
 
Overview

The Osram / Sylvania DED is a specialty 85W, 13.8V quartz tungsten-halogen lamp built in the MR16 reflector format to deliver controlled, repeatable illumination for optical and instrument platforms. It uses a GX5.3 bi-pin base and is commonly selected where precise filament/reflector alignment and consistent lamp seating are needed to support stable light delivery. (OSRAM global reference: 64618 | Americas product number: 54726.)

Key Highlights
  • Electrical: 85W, 13.8V (low-voltage)
  • ANSI Code: DED
  • Base: GX5.3 bi-pin (MR16 interface)
  • Shape: MR16 Reflector
  • Average Life: 1000 hours (nominal)
  • Design Notes: precision filament/reflector alignment (HLX architecture) for optical consistency
Typical Applications
  • Microscopy illumination platforms
  • Laboratory & analytical instruments
  • UV curing systems specifying DED MR16 reflector architecture
  • Fiber illumination light sources / light engines
  • Surgical & dental overhead lighting systems
Selection Tip (DED vs “Looks-Like” MR16 Lamps)
Many MR16 lamps share the same physical size and GX5.3 pins, but differ in voltage, filament geometry, and reflector behavior. To prevent mis-matches, qualify by ANSI DED and 13.8V first—then verify fixture requirements and operating position.
Handling Tip
Halogen reflector lamps run hot and are sensitive to contamination. Avoid touching the glass/reflector with bare hands. Use clean nitrile gloves and/or a lint-free wipe to minimize residue and reduce hot-spot failure risk.
Industry Update (Branding & Supply Continuity)
Ushio is scheduled to assume the U.S. Entertainment & Industry (ENI) lamp business as the legal contracting entity effective March 1, 2026. During this transition, customers may notice changes to branding, labeling, packaging, or invoicing entity even when the underlying lamp specification remains the same. SOSCleanroom will continue to support these lamps and can help qualify continuity by part number and critical specs (ANSI code, voltage, wattage, and base type) to ensure you receive the correct product across branding changes.
Need help selecting the right product?
Always confirm compatibility with your equipment model, required voltage (13.8V), ANSI DED specification, and base type (GX5.3) prior to installation.

Lamp Science (HLX Quartz Pinch + MR16 Reflector Optics)

In an MR16 reflector lamp, beam quality depends on the filament’s position relative to the reflector geometry. HLX designs use controlled quartz pinch manufacturing to help maintain repeatable filament alignment, which supports consistent focus and light delivery in optical engines (microscopy illumination trains, fiber coupling, UV systems, and surgical/dental heads).

Quartz tungsten-halogen chemistry supports the regenerative “halogen cycle,” reducing envelope darkening and helping sustain more stable output over life. Because these lamps operate at high temperature, clean handling and correct socket contact pressure are key reliability drivers.

Compare & Contrast (Why Specs Can Look “Inconsistent” Online)
DED is widely listed across the specialty lighting market and you may see different lumen values depending on catalog methodology (beam/fixture context vs standardized reporting). For qualification and continuity, treat ANSI DED, 13.8V, 85W, GX5.3, and MR16 as the primary identifiers.
Cross-Reference (Common Market Equivalents)
Common cross references for ANSI DED include: OSRAM 64618 / OSRAM/Sylvania 54726, GE 43950, and Ushio 1000180 (DED JCR13.8V-85W). Always validate your equipment’s voltage supply and fixture requirements prior to substitution.
Safety & Fixture Requirements
Halogen lamps may only be operated in suitable luminaires designed with protective mechanisms (shields/grids) to contain hot parts in the unlikely event of lamp bursting, and to prevent UV escape during operation. Allow full cool-down before handling.
Industry Update (Ushio & ENI Continuity)
Ushio is scheduled to assume the U.S. Entertainment & Industry (ENI) lamp business as the legal contracting entity effective March 1, 2026. During the transition, branding or packaging updates may occur even when lamp specifications remain unchanged. SOSCleanroom will continue supporting these lamps and qualifying continuity by part number and critical specifications.
