USHIO JC24V-300W FLW #1000545

Ushio 1000545 FLW JC24V-300WA-H — 300W 24V T4 Halogen Lamp, 3500K, GY6.35 2-Pin Base

The Ushio 1000545 FLW (JC24V-300WA-H) is a 300-watt, 24-volt T4 halogen lamp from Ushio, designed for professional projection systems, stage lighting, and specialty equipment requiring intense, focused low-voltage halogen output. With a GY6.35 2-pin base, CBAR6 filament, 3500K neutral white color temperature, 10,450 initial lumens, and a 50-hour rated life, this lamp is optimized for maximum light output in optical systems. Base-down burn position only. Requires a 24V transformer or electronic driver rated for at least 300W. Verify ANSI code, voltage, base type, and burn position before ordering.

Technical Specifications

Product Overview

The Ushio 1000545 FLW (JC24V-300WA-H) is a high-output 300-watt halogen lamp delivering 10,450 initial lumens at 3500K neutral white — optimized for professional projection and stage lighting applications where maximum brightness per watt is required over extended service life. The CBAR6 filament delivers a compact, intense arc-like light source suited for tight optical systems in slide projectors, overhead projectors, follow spots, and ellipsoidal spotlights.

Operating at 24V requires a dedicated step-down transformer or electronic driver rated for at least 300W — do not connect directly to 120V mains. This lamp is rated for base-down operation only — incorrect orientation degrades filament stability, reduces lamp life, and may cause premature failure. Confirm supply voltage is exactly 24V before installation.

Compatible Applications

• Professional projection systems — Eastman Kodak Ektalite L3 and L5, Elmo HP-285P and HP-285S, and compatible slide and overhead projectors.
• Stage lighting — Follow spots and ellipsoidal spotlights requiring ANSI FLW-designated low-voltage halogen sources.
• Medical and industrial inspection — Specialty optical equipment requiring high-intensity 24V halogen sources.

Before Ordering — Verify

• ANSI Code: Confirm the existing lamp or equipment manual specifies FLW.
• Voltage: Confirm the transformer or driver output is 24V. Do not operate on higher voltage — lamp burst risk.
• Wattage: Confirm transformer is rated for at least 300W.
• Base Type: Confirm lampholder accepts GY6.35 2-pin (6.35mm pin spacing) — not G6.35 or GZ6.35.
• Burn Position: This lamp requires base-down (BD) operation only. Horizontal or base-up installation will cause premature failure.
• Physical Dimensions: Confirm 2.17" MOL, 0.53" diameter, and 1.18" LCL fit your fixture's lamp housing.

Safety and Handling Guidelines

• High-pressure lamp — face shield required: Halogen lamps operate under high internal pressure. Always wear a face shield and protective gloves during handling and installation.
• 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.
• Base-down position only: Incorrect burn orientation will cause premature failure or lamp burst.
• Do not exceed 24V: Operating above rated voltage dramatically shortens lamp life and may cause rupture.
• Approved fixtures only: Use only in equipment designed for this lamp type with appropriate UV shielding.
• Allow complete cool-down before handling.

Compliance

• Verify UL/ETL listing status, RoHS compliance, and Prop 65 requirements with the Ushio manufacturer specification sheet prior to specification or installation.
