Installation Advantages:
-
Pre-Mounted VHB Adhesive – Professional-grade 3M tape for instant, secure mounting
-
Efficient Form Factor – 52mm x 44mm x 9.5mm provides maximum coverage per module
-
Wide Spacing Capability – 180-230mm centre-to-centre for faster installation
-
12V DC Operation – Compatible with standard power supplies for simple integration
System Planning Made Simple:
-
Per Module = 1.5W consumption, 240 lumens output
-
1m² Lightbox = Only 9 modules required
-
60mm Returns = 180mm centre-to-centre spacing
-
80mm Returns = 230mm centre-to-centre spacing (optimal efficiency)
-
Power Planning = Allow 20% headroom: 100W PSU = 53 modules max (79W)
