A practical multi-setting bulkhead for everyday project work

KSR Roma Select KSRSF400 is a round LED surface fitting designed to give installers and specifiers more freedom from a single product code. Instead of locking you into one colour temperature and one output level this model combines five selectable colour temperatures with three selectable wattages. That makes it easier to adapt the fitting to the room once you are on site rather than trying to predict every requirement during ordering.

The current Roma Select data sheet lists selectable outputs of 9W 14W and 18W together with selectable colour temperatures of 2700K 3000K 4000K 5000K and 6000K. Light output rises from 1015 lumens at 9W 2700K to a peak of 2135 lumens at 18W 4000K. In practical terms that means the same fitting can be used for softer warmer lighting in a residential or hospitality style setting or for brighter cooler lighting in circulation spaces utility zones and ancillary areas.

Why the Roma Select range works well on site

The Roma Select range is aimed at straightforward surface mounted general lighting where robustness matters as much as light quality. KSRSF400 is wall or ceiling mountable and suitable for BESA box mounting. KSR also includes four side conduit entry points which is a useful installation detail for projects where cable routing and surface containment need flexibility. That makes the fitting a stronger option for refurbishment work and communal spaces than a simpler decorative bulkhead with fewer entry options.

The fitting uses a polycarbonate body and polycarbonate diffuser with an ABS rim. That material mix supports impact resistance and day to day durability in shared areas. KSR rates the fitting at IK10 and IP65. For buyers that translates into a fitting that can cope better with knocks and harsher service conditions while also offering strong ingress protection for more exposed locations.

Lighting control without control gear complexity

One of the main commercial benefits of KSRSF400 is that you can set the fitting rather than change the fitting. Colour temperature can be adjusted from warm white through to cool white and output can be stepped from 9W to 18W. That helps reduce ordering errors and avoids over stocking multiple fixed-output variants. It also helps contractors standardise around a single range for repeated work across corridors stairwells washrooms service areas and entrances.

KSR quotes circuit wattage including driver losses at 9.18W 14.2W and 18.7W across the three output settings. Circuit current is listed at 0.051A 0.078A and 0.098A. The fitting is non-dimmable which is often the right choice for simple switching installations where reliability and low commissioning time matter more than layered lighting scenes.

Build and application strengths

With IP65 protection and IK10 impact resistance KSRSF400 sits comfortably in demanding general lighting applications. It is a good choice for communal corridors stairwells utility rooms plant access zones washrooms and covered external approaches where a low maintenance surface fitting is needed. The broad selectable specification also helps in mixed-use projects where one part of a building may need a warmer ambience and another part needs a crisper working light.

KSR positions the Roma family as a full bulkhead solution and that matters if you are planning consistency across a site. The same family includes emergency microwave and corridor function versions. There is also an optional chrome rim accessory under code KSRSF411 which allows a more decorative finish without changing the core fitting platform.

Who it suits

KSRSF400 is well suited to electricians contractors facilities teams and maintenance buyers who want one round bulkhead that can solve several lighting problems without overcomplicating installation. It is especially useful where stock efficiency matters because one fitting can be configured to suit different spaces at second fix. That can help cut van stock pressure and reduce the chances of arriving on site with the wrong CCT or output.

For buyers who value flexibility durability and straightforward installation this is a strong all-rounder. It delivers the core things most projects need from a bulkhead fitting which are adjustable light output adjustable light colour robust construction practical cable entry and a current family of related variants for emergency and sensor led applications.
