Product Overview

40° Beam Angle for Linear Accent Lighting

The L525 is an extruded optical lens with a nominal 40° beam angle and a cross-section measuring 20.0 mm wide × 8.5 mm high. It offers an optical option for linear luminaires intended to highlight selected surfaces, display areas or architectural details. Match the L525 to your project by reviewing the profile interface, LED configuration and target lighting area. The compact cross-section provides a clear starting point for mechanical integration, while the nominal beam angle guides optical evaluation.

Nominal 40° Beam Angle — An optical specification for evaluating targeted linear lighting.
20 mm Lens Width — A defined cross-section for comparison with your aluminum profile.
8.5 mm Lens Height — A key dimension for planning internal assembly space.
Accent Lighting Applications — For consideration in luminaires designed to emphasize selected areas or features.

Dimensions & Mounting

Check the 20 × 8.5 mm Lens Interface

The L525 measures 20.0 mm in overall width and 8.5 mm in overall height. Compare the detailed lens cross-section with the profile opening, seating surfaces and retaining features. A profile described as “20 mm” may refer to a different dimension from the lens width. Confirm the actual mounting interface and the available space around the LED board before selecting the assembly.

Profile Dimensions — Distinguish the profile’s external width from its lens opening and internal clearance.
Retaining Geometry — Check how the lens seats and is held within the profile.
LED Alignment — Confirm the LED position and clearance relative to the lens.

Optical Performance

Evaluate the 40° Beam on Your Target Surface

The L525 has a nominal 40° beam angle. Actual distribution depends on the LED source, emitter arrangement and position relative to the lens. For wall accents and other directional lighting layouts, assess the mounting distance, fixture orientation and position of the target surface. Evaluate the complete assembly to confirm coverage, uniformity and spill light.

Nominal Beam Angle: 40°
Evaluation Inputs: LED model, emitter spacing and lens-to-LED position
Installation Factors: Mounting distance, fixture orientation and target surface location

Product FAQ

Before you choose L525 40° Extruded Optical Lens for LED Linear Lighting — 20 × 8.5 mm

What are the dimensions of the L525 lens?

The L525 measures 20.0 mm wide × 8.5 mm high, approximately 0.79 × 0.33 inches. These are the overall cross-section dimensions.

What is the beam angle of the L525?

The nominal beam angle is 40°. Evaluate the resulting distribution with the intended LED source and mounting geometry.

Can the L525 be used for wall lighting?

It can be considered for wall accent applications. Coverage and uniformity depend on the complete optical assembly, fixture setback, mounting angle and target surface. Uniform wall-washing performance should be confirmed through testing.

Will the L525 fit any 20 mm LED profile?

Compatibility cannot be established from the stated width alone. Compare the profile opening, retaining features and internal clearance with the detailed lens cross-section.

What information should I provide when requesting a quote?

Include the L525 model number, required length and quantity, profile drawing and LED configuration. For accent lighting projects, also provide the mounting distance, fixture orientation and target area.
