Martin Exterior Linear Pro-Graze CTC 4ft – IP66 Outdoor Color Temperature Linear Fixture

Product Overview

The Martin Exterior Linear Pro-Graze CTC 4ft is a permanent outdoor architectural linear fixture delivering precise color temperature control for facade graze and wash applications where consistent, high-quality white light is the design intent. Using warm, neutral, and cold white LEDs (2700K, 4000K, 6500K) at 12 LEDs per foot with a 9° ultra-narrow beam angle, it provides the highest output-per-watt of any EL Pro variant at up to 3,730 lumens per 4ft fixture. Rated IP66, IK08, and C5 corrosion resistance, it is suitable for permanent installation in coastal and marine environments. The ASHRAE-compliant 5W/ft power mode makes it a strong specification choice for energy code-sensitive architectural projects.

Product Description

The Exterior Linear Pro-Graze CTC uses 12 LEDs per foot in warm (2700K), neutral (4000K), and cold (6500K) white channels, individually controllable to produce any color temperature from 2700K to 6500K via DMX. Full Gamut Color Calibration to 1-step MacAdam ellipse ensures consistent white appearance across all fixtures in a run. Segment control modes divide the 4ft fixture into 1, 4, or 8 independently addressable segments for zone control and creative programming. Three selectable power modes (12W, 10W, 5W per foot) support ASHRAE compliance when operating at 5W/ft.

Interchangeable micro lens films allow asymmetric beam angle modification from the standard 9° to 9°×30° or 9°×60° without hardware changes. The hybrid 8-pin PD connector enables daisy-chaining of up to 42 fixtures at 230–277V. DMX-512A and RDM (ANSI E1.20) are standard, with 20-scene stand-alone programming. The CTC variant is the highest-efficacy option in the EL Pro range due to its white-LED engine.

Technical Specifications

FAQs

What is the difference between the CTC and QUAD variants?

The CTC variant uses three dedicated white-LED channels (2700K, 4000K, 6500K) for precise color temperature control and highest lumen output. The QUAD variant uses RGBW LEDs for full color mixing plus CCT control. Choose CTC for white-only applications requiring maximum output or precise tunable white.

Can the beam angle be changed?

Yes. Interchangeable micro lens films modify the standard 9° beam to 9°×30° (asymmetric wide) or 9°×60° (asymmetric extra-wide) without hardware changes to the fixture.

What is the IP and corrosion rating?

IP66, IK08, and C5 marine-grade corrosion resistance per ISO 12944-6. Suitable for coastal and industrial permanent installation.

How does ASHRAE compliance work?

When operating at 5W/ft power mode (selectable via DMX), the fixture meets ASHRAE facade lighting energy standards. No hardware modification is required.

What is the warranty?

Martin provides a 5-year warranty on all Exterior Linear Pro fixtures in permanent architectural installation.
