What this product is

Sitio KSR5403 is a 5ft single 24W 110V LED anti corrosive batten designed for temporary site lighting. It sits above the 2ft and 4ft single versions in the Sitio anti corrosive family and is intended for buyers who need a longer fitting with more output, while still staying with a single-batten format rather than moving to the 5ft twin model. KSR positions the Site Light Series as specialised 110V site lighting for domestic, commercial or industrial applications, and this model is the longest single-body standard version in that family group.

This makes KSR5403 especially useful where a longer run is needed from each fitting position. In practical terms, it helps reduce the need to use shorter battens where a single 5ft unit would suit the space more naturally.

Key verified technical details

• 24W LED light source
• 4000K colour temperature
• 3145 lumens
• CRI above 80
• 120 degree beam angle
• 110V supply only
• IP65 protection
• 3 year warranty
• L70 rated life of 40,000 hours

The lift in wattage and lumen output compared with the 19W 2ft and 4ft models gives KSR5403 a clear role. It is not only longer physically. It is also brighter, which helps it suit larger or more open temporary working areas where a more substantial single batten is the better match.

Construction and installation context

KSR specifies a polycarbonate body, opal polycarbonate diffuser and 304 stainless steel clips. That construction is well aligned with the temporary site environments the product is intended for, where durability and resistance to harsher conditions matter. IP65 protection is one of the main reasons to specify this type of fitting for site use, especially where dampness, dust and general contamination are likely.

The family datasheet also states BESA-box mountable brackets, which adds installation flexibility, and KSR lists the KSR98195 plug and play microwave sensor as an available option for the range. Those details help make the fitting easier to integrate into a broader temporary lighting plan without moving outside the Sitio family.

Why choose the 5ft single variant

The main reason to choose KSR5403 is that it gives you a longer single-body fitting with a higher 24W output. At 1485 x 85 x 80mm, it is a proper step up from the 4ft single version. That makes it better suited to longer temporary runs, broader walkways, larger site cabins and work areas where the added body length and output are useful.

It is also the right specification where a standard non-emergency product is suitable. If the same 5ft single body is needed with maintained emergency function, KSR5403/EM is the matching upgrade. If a larger twin-body 5ft fitting is required instead, that sits elsewhere in the range as a different variant choice.

Why buy this exact version

KSR5403 is a straightforward but important product in the Sitio 110V anti corrosive family. It combines the longer 5ft single format with 24W LED output, 3145 lumens, 4000K colour, IP65 protection and a site-ready construction. For buyers who need more length and more output than the 19W variants provide, but do not need an emergency pack or a twin fitting, this is the cleanest choice in the range.
