Product Overview

The GE 34813 CSS150/CAP/50 is part of GE's SSTV (Stage, Studio and Theater/Videoconferencing) Ceramic Metal Halide lamp series, engineered for professional entertainment and broadcast environments where consistent color rendering, stable output, and reliable performance in demanding optical systems are required. The CSS ceramic arc tube technology produces stable 3000K warm white output with CRI 80 — delivering more consistent color over lamp life compared to conventional quartz metal halide designs.

CSS short-arc lamps are specifically designed for moving light fixtures and projection systems where the compact arc source and high luminous intensity are optimized for tight optical control. This lamp requires a DC power supply — CSS/CSR metal halide discharge lamps operate on direct current, not standard AC mains. An ANSI M81-compatible DC ballast is required. Using an incorrect power supply or ballast will immediately damage the lamp. Always confirm lamp code and equipment ballast specifications against your fixture manufacturer's documentation before ordering.

Compatible Applications

Moving light fixtures — Professional moving head wash and beam fixtures in entertainment, concert, and theatrical production specifying CSS 150W lamps.
Projection systems — High-output optical projection equipment requiring 150W CSS short-arc CMH sources.
Stage, studio, and broadcast lighting — Professional entertainment and videoconferencing fixtures requiring SSTV-class ceramic metal halide sources.

Before Ordering — Verify

Lamp Code: Confirm your fixture manual specifies CSS150/CAP/50 or ANSI CAP (M81). CSS lamps are equipment-specific — verify against fixture manufacturer documentation.
Power Supply: Confirm your fixture uses a DC power supply. CSS/CSR lamps require DC operation — they will not function on AC ballasts.
Ballast: Confirm the ballast is rated for ANSI M81 CSS 150W DC operation.
Base Type: Confirm the lampholder accepts GY9.5 2-Pin.
Burn Position: Confirm your fixture mounts the lamp in the correct orientation — CSS short-arc lamps have specific burn position requirements. Verify against fixture documentation.
Physical Fit: Confirm 1.62" MOL fits within your fixture's lamp housing.

Safety and Handling Guidelines

DC Power Required: CSS/CSR metal halide lamps require a DC power supply. Using AC power or an incompatible ballast will damage the lamp immediately.
High-Pressure Lamp — Face Shield Required: These lamps operate under high internal pressure. Always wear a face shield and protective gloves during handling and installation.
Do not touch the lamp 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.
Observe Rated Burn Position: Operating outside the rated orientation can cause premature failure or lamp burst.
High UV and Heat Output: Use only in approved enclosed luminaires with appropriate UV filtering.
Allow Complete Cool-Down: Allow the lamp to cool completely before handling or relamping — do not touch immediately after switching off.
