What this product is

Sitio KSR5402 is a 4ft 19W 110V LED anti corrosive batten designed for temporary site lighting. It sits between the 2ft and 5ft single versions in the Sitio range, giving buyers a medium-length option where a shorter batten would not provide enough physical coverage, but a 5ft unit would be unnecessary. KSR presents the Site Light Series as 110V specialised site lighting for domestic, commercial or industrial applications, and KSR5402 fits that brief as a standard non-emergency IP65 batten.

The value of this variant is its proportion. The 4ft body allows a more stretched fitting layout than the 2ft version, but it still keeps power demand at 19W. That makes it a practical option for temporary lighting runs where body length is the bigger requirement rather than a major jump in wattage.

Key verified technical details

• 19W LED light source
• 4000K colour temperature
• 2480 lumens
• CRI above 80
• 120 degree beam angle
• 110V supply only
• IP65 protection
• 3 year warranty
• L70 rated life of 40,000 hours

Those figures make KSR5402 easy to understand. It gives near-identical wattage to the 2ft KSR5400, but in a longer body format. That changes the physical suitability more than the electrical demand, which is often exactly what temporary site planners need.

Construction and installation context

KSR specifies a polycarbonate body and opal polycarbonate diffuser with 304 stainless steel clips. That is a practical construction mix for temporary environments where site fittings may be exposed to dirt, moisture and more demanding handling than standard indoor luminaires. IP65 protection supports that site-ready position, while Class I construction keeps the electrical specification clear.

The family datasheet also states that the range is BESA-box mountable via brackets. That is helpful where the installation method needs to stay flexible. KSR additionally lists a plug and play microwave sensor option, KSR98195, for the range. That can be useful where the project benefits from adding a compatible sensor rather than keeping the fitting on a simple fixed operation basis.

Why choose the 4ft variant

The main reason to specify KSR5402 is body length. At 1180 x 85 x 80mm, it gives a noticeably longer fitting than the 2ft model while staying slimmer than the twin 5ft versions elsewhere in the range. It is therefore a sensible fit where a medium-length batten suits the area better, such as temporary walkways, work zones or site cabins where one short fitting is not enough and a 5ft body is more than is needed.

It is also the right choice where emergency lighting is not required. For sites that need the same 4ft format with maintained emergency operation, the matching KSR5402/EM variant provides that upgrade path. That makes the buying decision simple and avoids moving outside the Sitio anti corrosive family.

Why buy this exact version

KSR5402 is a clear, well-positioned 4ft option in the Sitio 110V anti corrosive range. It combines IP65 protection, a 4000K LED light source, 2480 lumens, stainless steel clips and a longer single-batten body that suits medium site runs well. If the 2ft version feels too compact and the 5ft family feels larger than necessary, this is the strongest middle-size choice in the standard non-emergency lineup.
