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 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 LD74SR High power Ultra shallow Recessed Downlight Data sheet - Page 1 The LD74SR 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 LD74SR fits into a ceiling depth of only 40mm, whilst delivering over 357lm, making 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.
