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

Cone diagrams below are based on a 3000K F1 LED engine run at maximum output 700mA,

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
