KEY FEATURES Dimensions in mmDIMENSIONS Design: Lighting by Plum Project: Private Residence Product: LD43DR Ø36 2.4 Ø27 DEEP RECESSED MINIATURE INTERIOR/EXTERIOR LED UPLIGHT LD43DR The LD43DR is a miniature, ultra-deep recessed, LED in-ground uplight which can also be used as a downlight. The LED and optics are deep recessed 33mm into the body for super low glare, which can be further reduced with an optional glare shield. Due to the miniature aperture of the LD43DR, it is available in a narrow 12° beam only, offering defined edges, ideal for lighting doorways or narrow corridors. Featuring a high-quality machined bezel, a wide range of metal and paint finishes are available.

The tube can be buried with the necessary wiring, and then the fitting installed after the landscaping work has been completed. It is supplied with the fixing sleeve bonded into the tube, and can be cut down on site.

Data sheet issued: 8 April 2026 | Issue 7 GLARE CONTROL OPTIONS /GS Glare shield An optional glare shield is available to further reduce glare from the LED and optic. This is useful in narrow details where people are going to walk directly over the fitting. This does not reduce the light on the lit surface (wall) but will cut out some light onto the ceiling. 2.4 Cut-Out Ø32 /480 Fixing Sleeve with ‘O’ rings Ø36 2.4 Ø27 Cut-Out Ø32 /SC Spring Clips Ø36 Ø27 Scaled Drawings.

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. Threaded back plate RLE 1 ENGINE HeatsinkOptic LED O-ring RLE1/
