    Klus Serpent Plus: serpentine runs and rings of jointed LED modules threading across a commercial ceiling
    Klus Serpent Plus · Bespoke system

    When the ceiling is the design

    For offices, galleries, hotels, restaurants and showrooms where a grid of panels would waste the room. Serpent Plus is a 48mm system of straight and curved modules that join magnetically, so the luminaire is whatever shape you draw — a racetrack over the boardroom table, a ring above reception, a serpentine down the circulation — in one unbroken line of light.

    • UGR<19 with microprism, or down to UGR<10 with DOT where the room is screen-heavy

    Lighting for Every Kind of Business Space

    Every business space has different needs — a quiet office wants soft, even light; a shop wants something more dramatic to show off products. We stock fittings to suit all of them, and we're happy to suggest a few options if you're not sure where to start.

    Offices & Co-working

    Comfortable, low-glare lighting that's easy on the eyes through a long working day. Panels, recessed downlights and linear pendants all work well.

    Shops & Retail

    Bright, flattering light that shows off your stock. Track lighting and accent spots let you direct attention to displays and rearrange them as you go.

    Cafés & Restaurants

    Warm, dimmable lighting that sets the mood — usually a mix of pendants over tables, soft downlights overhead and accent lighting on bars and counters.

    Hotels & Hospitality

    Layered lighting for lobbies, corridors and guest areas, with controls that can shift the feel from morning bright to evening cosy.

    Salons, Studios & Clinics

    Clean, true-to-life lighting where colour matters — for hairdressers, beauty rooms, dental practices, photography studios and similar settings.

    Workshops & Storage

    Bright, robust fittings for back-of-house, stockrooms, garages and small workshops — battens, bulkheads and high bays do the heavy lifting.

    Outside the Building

    Floodlights, bollards, in-ground uplights and façade lighting for entrances, car parks, signage and outdoor seating.

    Stairs, Corridors & Communal Areas

    Hard-wearing fittings with the option to add motion sensors and emergency back-up — practical lighting for the parts of a building everyone passes through.

    Energy-Efficient Lighting That Pays You Back

    Lighting is one of the easiest places to cut a business's running costs. Swapping older fittings for LED, and adding simple controls like dimmers or motion sensors, usually pays for itself within a couple of years — and the lights look better while they're doing it.

    A Few Things Worth Thinking About

    You don't need to be a lighting expert to plan a business space — but a handful of things are worth bearing in mind early on. We're happy to talk any of these through, and for anything wiring-related your electrician will be the right person to involve.

    Emergency Lighting

    If the public visits your premises or staff work on-site, you'll usually need emergency lighting on escape routes. It's a quick add when you're already changing fittings.

    Bathroom & Wet Areas

    Fittings in toilets, showers and outdoors need to be rated for moisture. We can guide you to the right ones — see our bathroom zones guide for the basics.

    Energy Rules for New Builds

    New buildings and major refurbishments have stricter rules on how efficient the lighting needs to be. If that applies to your project, get in touch and we'll point you at products that fit.

    Insurance & Landlord Approvals

    Some leases and insurers have their own requirements for lighting — particularly emergency lighting and signage. Worth a quick check before you order.

    Dimmable vs Non-Dimmable

    Decide up front whether you want to dim. Dimmable fittings cost a little more but give you a lot more flexibility — especially in restaurants, salons and hospitality settings.

    Talk to Your Electrician

    Anything that gets wired in should be installed by a qualified electrician. We're happy to liaise with them on the technical side — wiring diagrams, drivers and control gear.

    Smart Lighting Controls, Made Simple

    Smart controls used to be the preserve of big-budget projects. They aren't any more. A handful of dimmable fittings and a wireless control system like Casambi — or, for larger commercial spaces, Lutron Vive — can transform how a space feels, and we'll happily talk through what's possible if you're not sure where to start.

    Commercial Lighting FAQs

    The questions we get asked most often by shop, café and office owners

    What kind of lighting is best for a small office?

    For most small offices, a mix of recessed downlights or LED panels overhead — with a softer pendant or two over meeting tables — gives an even, comfortable light. We'd suggest dimmable fittings if your budget allows: it makes the space far more pleasant in the late afternoon and evening. Pop in and we'll talk it through with you.

    DALI or Casambi — what's the difference?

    Both let you dim lights and group them into zones. DALI is wired — it's a good fit if your electrician is putting in new cabling anyway. Casambi is wireless and runs from a phone app over Bluetooth, which makes it the easier choice if you're updating an existing space without rewiring. For larger commercial fit-outs that need occupancy and daylight sensing across many zones, Lutron Vive is a third, fully wireless option. We're happy to demo any of them in our Wandsworth showroom.

    Do I need emergency lighting in my premises?

    Most business premises do — including shops, cafés, restaurants, offices and salons. The basic idea is that if the power fails, there's still enough light for people to find their way out safely. The specifics depend on your space, so it's worth checking with your electrician or fire-risk assessor. We can supply emergency luminaires and illuminated exit signs to suit.

    How much money will switching to LED actually save me?

    It depends on what you've got now and how long the lights are on each day, but the savings are usually substantial. A café that's lit twelve hours a day might pay back the cost of switching within two or three years — and then save on its electricity bill from there on out. Send us your existing fittings and we can give you a rough comparison.

    Do you offer a lighting design service?

    Yes. Our in-house design team offers three levels of service — from a quick consultation in the showroom through to full plans showing where every light goes. We've worked on shops, restaurants, offices and salons all over London. Read more about our design service.

    What lighting should I use in a restaurant or café?

    Warm white light (around 2700K) and dimmable fittings, layered to create different zones — pendants over tables, soft downlights overhead, and a bit of accent lighting on the bar or feature walls. The ability to dim from bright at lunchtime to cosy in the evening makes a huge difference to how the space feels.

    What's the best lighting for a warehouse or workshop?

    For high ceilings, LED high bays give plenty of light over a wide area. For lower ceilings, IP-rated battens or weatherproof fittings tend to do the job. Motion sensors are a good addition for aisles and storage areas that are empty for most of the day — they'll switch the lights on only when someone's actually there.

    Can you help with lighting outside the building?

    Yes — floodlights, bollards along paths, in-ground uplights for façades, and outdoor wall lights for entrances and signage. Anything outside needs to be weather-rated, and we'll point you to the right ones. For larger outdoor schemes, our design team can put together a plan.
