PHILIPS ADVANCE IMH39GBLS | 39W Electronic Metal Halide Ballast | 120-277V

The Philips Advance e-Vision IMH39GBLS is a high-performance electronic ballast designed for 39-watt small-format metal halide lamps. Part of the e-Vision mini-square family, this ballast provides superior energy efficiency and lamp life compared to traditional magnetic systems. Featuring IntelliVolt technology, it automatically operates on any input voltage from 120V to 277V. This specific "BLS" model is configured with bottom-exit leads and mounting studs, making it ideal for compact track heads and recessed downlights where space is at a premium and a clean, concealed wiring setup is required.

Product Overview

The IMH39GBLS is engineered with advanced End-of-Life (EOL) detection, which removes power from the lamp if it behaves erratically or fails to ignite within 20 minutes, preventing fixture damage and thermal stress. Its small, square metal housing ensures maximum heat transfer and durability compared to plastic alternatives. This ballast is compatible with a variety of 39W ceramic metal halide lamps, including MR16, PAR20, GU6.5, and G8.5 formats, making it a versatile choice for high-end retail and commercial display lighting.

• Universal Voltage: IntelliVolt technology handles 120V through 277V for simplified stock and installation.
• Enhanced Safety: Automatic shutdown circuitry prevents lamp cycling and reduces thermal stress on the fixture.
• Compact Form Factor: Mini-square design fits easily into tight architectural lighting enclosures.
• Mounting Ease: The BLS configuration provides 2-inch mounting studs and leads exiting from the bottom for a secure, hidden attachment.
