CEILING VOID REQUIREMENTS
Installation requirements can vary but the minimum installation volume requirements must be adhered to. The volume of air within the void ensures that the thermal performance of the
product is not compromised and that proper cooling of the LED can take place. The minimum void height is 70mm.

E3 LED Engine
Cone diagrams below are based on a 3000K E3 LED engine run at maximum output 500mA,
7W. Images below represent beam outputs when wall washing a 3m wall, spaced 125mm
away from the lit surface. Photometric files (LDT) are included in the design pack which can
be downloaded from the LD780 product page on the website.
F1 LED Engine
