Lighted Stair Nosing

LED Lighted Stair Nosing/Stair Treds

The Advance Interlock LED system is the result of extensive research and development. The modular electrical system combined with an insulating nosing system incorporates the safety and durability of the proven stair systems and provides an easily assembled, extremely low maintenance, maximum appearance with low energy and running costs.

Power Supply Units

Novaproducts Global offers a range of direct current (D.C.) power supply units which are designed to transform power from the mains to a 12v or 24v system, thereby providing a safe and efficient power source to low level lighting systems. Novaproducts Global offers a wide range of power supply units including dimmable and battery backup units. Gradus Technical Services can provide a full calculation service to aid with quantity needed. Datasheets are available on request.


All electrical mains supplies and direct hard wired connections to the mains supplies must be installed by qualified electricians. Interlok Advance and Continuity LED operate on extra low voltages and therefore do not represent a safety hazard when used correctly. Always ensure that Gradus systems are connected to a Gradus power supply unit or other approved power. They must never, under any circumstance, be connected directly to the mains supply.
The systems must be isolated from the mains supply prior to any work being undertaken on them, preferably by disconnection or removal of the primary fuse. In the case of new installations, the electrical connection must be made last.
