FAQ
Is ACP safe to use around LED modules?
Yes — LED signage runs cool; ACP stays dimensionally stable and gives you clean routed channels for wiring and module mounting.
Can ACP be the illuminated face itself?
ACP is opaque, so it's used for bodies, returns, backs and halo-lit letters — pair it with acrylic for the light-transmitting faces.
What about backlit day/night effects?
Mirror and brushed faces with halo lighting give a premium day look and a dramatic night glow — see Mirror ACP.
