What this product is

Sitio KSR5425 is a 4W 110V LED emergency twin spot designed for commercial or industrial site applications. KSR positions it in the Site Light Series and describes it as a non-maintained emergency fitting that is ideal for various emergency applications in warehouses and other large open spaces, both internal and external. That gives the product a very different role from the standard site lights in the range.

This is not a general-purpose bulkhead and it is not a normal working light. It is a dedicated emergency twin spot intended to provide directional emergency illumination from two adjustable heads in larger spaces where a simple bulkhead may not be enough.

Why the twin-spot format matters

The main benefit of KSR5425 is that it uses two heads rather than a single bulkhead diffuser. That gives the fitting a more directed emergency lighting format, which is useful in larger spaces where coverage needs to be aimed and spread more deliberately. KSR specifically references warehouses and large open spaces, which is exactly where twin-spot emergency luminaires are commonly chosen.

Because it is non-maintained, it is intended to operate in emergency mode rather than as a normal everyday lighting fitting. That makes the buying decision clearer for projects that need emergency-only operation.

Construction and site suitability

KSR specifies a polycarbonate body and diffuser, together with IP65 ingress protection and IK08 impact resistance. Those details help make the product more suitable for site and industrial environments than a light-duty indoor emergency unit. The 110V-only supply also keeps it aligned with temporary site power arrangements.

Dimensions and installation

KSR publishes the body dimensions at 296mm width, 190mm height and 70mm depth, with an overall height of 295mm. Each head is shown at 125mm width, 75mm height and 65mm depth. Those dimensions help make it easier to plan mounting positions for larger emergency coverage areas.

Why choose this exact SKU

KSR5425 is the correct choice when the requirement is a 110V IP65 emergency twin spot for larger commercial or industrial spaces. It combines non-maintained emergency operation, twin adjustable heads, verified impact and ingress protection, and a product brief clearly aimed at open emergency coverage rather than normal area lighting.
