Page 3 of 8 | Data sheet issued: 10 April 2026 LD34 AVAILABLE FINISHES LD34 has been designed for extreme environments therefore only high quality materials and finishes are used to ensure long lasting reliability. All parts are silver anodised to a minimum thickness of 25 microns which offers high protection in all external environments. Though we offer paint finishes, we do not recommend using them in high-traffic areas. SILVER ANODISED (SUPPLIED AS STANDARD FINISH) CLASSIC BRONZE (YM262E) TEXTURED FIR GREEN (RAL 6009) GUN METAL GREY (RAL 7021) RAL COLOURS BLACK (RAL 9005) WHITE (RAL 9016) POWDER COAT Powder coat paint is offered in special textured finishes, which are suitable for interior, exterior and high-saline environments.

Page 4 of 8 | Data sheet issued: 10 April 2026 /CH Concrete Housing DIMENSIONS & FIXING OPTIONS /GL Anti-glare louvre. LD34 can be supplied with a glare louvre however the /GS40 is recommended as it provides the same amount of glare protection and delivers a better lit effect on the wall. Please note this is always supplied in a black finish, and is supplied as standard with the louvre positioned to reduce glare when looking at the lit surface. ACCESSORIES SIMILAR PRODUCTS LD34MI Same specification as the LD34 but with a mains-in connection system to allow for easier, quicker and a more cost effective installation on-site. Set lengths available only. LD38 LD34 has been designed alongside our interior wall grazer LD38 to enable seamless integration of both products throughout a project.

Page 5 of 8 | Data sheet issued: 10 April 2026 LIGHT DISTRIBUTION AND GLARE SHIELD OPTIONS 10m LD34 No glare shield for maximum lumen output. Deep recessed optic and matt black cowl aids in glare reduction. /GS40 with /FD 40% glare shield and diffusion film combination. The aperture allows the main punch of the beam to leave the fitting, providing glare protection from one side and moving the start of the beam down to the floor on the other. /GS40 Teamed with the 2.5° fixed tilt the 40% glare shield provides glare protection with only a 28% reduction in lumens. /GS50 Half glare shield. For an increased cut-off angle and greater glare control. Not available with Wide Beam optics. Please note this is a graphical guide to the expected light output, refer to the photometric files for more detailed data. /FD This accessory is particularly useful when the LD34 needs to be placed further away from the lit surface. It provides a smooth consistent beam that starts as close to the bottom of the lit surface as possible. The frosted diffusion film can be specified with any of the glare shield options but we recommend using it with the /GS40 for best results. 0.6 0.5 0.4 0.2 0.1 0.7 0.3 0 10.5 1.5 Distance Between Fittings (m) Offset, centre of optic to surface (m) 0.9 0.8 1.0 0.6 0.5 0.4 0.2 0.1 0.7 0.3 0 10.5 1.5 Distance Between Fittings (m) Offset, centre of optic to surface (m) 0.9 0.8 1.0 /GS40 /GS40 with /FD FROSTED DIFFUSION FILM

Every project and lighting scenario will be different but the table below is to be used as a starting point for any wall wash design. Please use our photometric files to further test the desired effect for your application which are available to download on the LD34 product page on our website. INSTALLATION GUIDE C B D A Option Code Description Use A LD34 Standard LD34 The standard LD34 can be used when maximum output is required. This option achieves a throw of up to 20m. Even without the presence of a glare shield the cowls over each optic provide a good amount of glare control. B /GS50 Glare shield with 50% optic coverage This option has been designed for use when glare control is the priority and is ideal for narrow corridors and walkways. Not available with Wide Beam optics. C /GS40/FD Glare shield with 40% optic coverage and linear diffusion strip. This option has been designed to lower the starting position of the beam on the lit surface. This is useful for lighting low walls or when the fitting must be placed further away from the lit surface. D /GS40 Glare shield with 40% optic coverage Ideal for use in walkways and arches where glare control is needed as well as a good punch up the wall.

Page 7 of 8 | Data sheet issued: 10 April 2026 E LD34 features the ability to create outstanding continuous wall washing capabilities, by seamlessly connecting multiple fittings while maintaining consistent LED spacing. F LD34 can be supplied with an extra oval beam /EOB. This 15° x 60° optic and film combination allows fittings to be spaced apart from each other but still produce a consistent lit effect.

LENGTH GUIDE The LD34 is available in 7 set lengths to enable maximum flexibility, 150mm, 350mm 450mm, 600mm, 750mm, 1050mm and 1350mm, with LED’s spaced at 50mm and 75mm. When selecting a length please note that a total of 18mm will be added to a single length or total run length to account for the flanged end cap.
