Page 1 of 7 | Data sheet issued: 8 April 2026 > Machined domed body offers an ultra low glare solution by obscuring the light source from view and directing it only onto the lit surface > High-power C1 engine with NICHIA LED delivering up to 73lm > Miniature fitting with very minimal body depth and bezel diameter > Optional 20° Tilt lens to focus the light down onto to the lit surface > Range of beam angles including new Extra Oval beam, a wall grazing optic now available for floor washing across the LD42 range > Wide range of high-quality machined metal and painted bezel finishes available, including: 316 Stainless Steel, Polished & Passivated 316 Stainless Steel, Machined Brass, Flamed Solid Bronze, White (RAL 9016), Black (RAL 9005), Antique Bronze, Satin Antique Brass, Satin Brass, Anthracite Grey (RAL 7016) or any RAL colour > Use with our LD43 uplight for a uniform floor and wall washing effect > Hidden fixing options include spring clips or /480 first fix sleeve with o-rings > Switched, 0-10V, casambi, DMX, DALI or mains dimmable drivers available KEY FEATURES DIMENSIONS For fixing dimensions please go to page 3. Ø27 Ø36 Dimensions in mm ULTRA-LOW GLARE MINIATURE SEMI-RECESSED DOMED LED WALL LIGHT The miniature LD42D is ideal for discreet lighting of steps and pathways within interior, exterior and marine applications. The fitting is an evolution of our popular LD42, offering a new bezel aesthetic. When viewed from above, the machined, domed bezel obscures the light source, resulting in ultra-low glare. LD42D offers a powerful floor wash reaching up to 3 metres, with an optional 20° Tilt lens to focus the beam down onto the lit surface. With Narrow to Oval beam angles available and a high IP rating, a range of lighting effects can be created even in the harshest environments. LD42D

However for us, RLE is an ethos; a commitment that LightGraphix will factor in the principles of good circular design into all of its future product design. It allows us to offer luminaires that contain replaceable, energy-efficient light engines. This gives customers the ability to refurbish existing lighting installations rather have having to replace the entire luminaire. This will fall into two types of refurbishments: replaceable, and repairable. RLE Engines Repairs can be conducted on any site worldwide, or in our factory, with a small tool. Simply swap out the singular modular LED insert, and replace it with another, along with a new optic, which are both supplied by us. The warranty provided with the product with vary based on who is performing RLE repairs. There are three types of RLE engine, categorised based on the size of the product. RLE1 is the smallest, with RLE3 being the largest. LD42, LD42D, LD43 & LD43G Used in the following products: Optical Film Can be tilt lenses, frosts or both Optic
