LightGraphix reserve the right to change specifications without notice Data sheet issued: 2 February 2023 Only 40mm ceiling depth required 357 delivered lumens Innovative horizontal heatsink plate Adjustable with a 25° tilt High power to size ratio Recessed LED position for reduced glare
93 CRI LEDs
Hidden fixing with spring clips Developed for simple, quick installation Available with Switch, 0-10V, DMX, Dali or Mains dimmable drivers LD73SR High Power Ultra Shallow Adjustable Recessed Downlight Data sheet - Page 1 The LD73SR is part of a new range of ultra shallow, high power downlights designed to fit into ceilings with a minimal recess depth. The innovative horizontal heatsink plate combined with low profile optics ensure that the LD73SR fits into a ceiling depth of only 40mm, whilst delivering over 357lm. The tilt adjustment of 25° allows plenty of flexibility when focusing and makes it ideal for general lighting or display applications. Originally designed for yacht installations, this fitting can be specified with an extra red LED for night time navigation. It is rated IP54 as standard making it ideal for use in wet environments.
