The Stairville BEL4 Battery Event Light 4x15W brings elegant, cable-free illumination to any space. Featuring red, green, blue, white, and amber LEDs, it produces rich, natural colour blends – from warm tones to soft pastels – that make any setting shine. A built-in UV light adds an extra layer of atmosphere, perfect for parties or stage effects. Whether placed on the floor as an uplight or mounted overhead, the BEL4 provides striking decorative lighting without the clutter of cables. Its long battery life ensures dependable performance during events, and it comes complete with a charging cable and remote control. Wireless DMX (WDMX) capability offers added flexibility, while the rugged housing and optional rolling case – which enables the device to be charged in storage – make it a durable, tour-ready lighting solution.
The Stairville BEL4 Battery Event Light 4x15W offers professional performance in a sleek, portable form. With its four 15-watt RGBAWUV LEDs, it produces a rich palette of vibrant tones from bold primaries to smooth pastels and eye-catching UV highlights. Its 20° beam strikes the ideal balance between wide coverage and focused intensity, making it perfect for uplighting, stage design, or ambient accent lighting. Designed for flexibility, the BEL4 includes nine preset colour mixes, variable-speed fade and colour-change programmes, and built-in sound-to-light and strobe effects for dynamic, music-synced visuals. Control options are equally versatile – choose from onboard menu navigation, DMX or WDMX integration, or the infrared remote (included – it requires a clear line of sight to the base unit). With a quick five-hour charge via the included Power-Twist cable or an optional six-unit charging case, the BEL4’s long-lasting Li-ion battery provides up to 20 hours of wireless operation.
The Stairville BEL4 Battery Event Light 4x15W combines stylish design with reliable performance, delivering vibrant decorative effects for small stages, bars, parties, and mobile setups. For larger venues, multiple units can be linked in master-slave mode for synchronised control. Even without technical experience, users can create a captivating light show right out of the box thanks to an intuitive onboard menu as well as the infrared remote control it ships with. The Stairville BEL4 offers a wide selection of pre-programmed mixed colours and dynamic effect programmes, with sound control via the built-in microphone for perfectly timed, music-responsive lighting. For more advanced users seeking full creative control, the BEL4 offers 6- or 10-channel DMX operation, enabling precise adjustment of each RGBAWUV LED for custom colour blends and effects. Multiple units can be effortlessly linked through the three-pin DMX in/out ports for perfectly synchronised shows across larger setups.
Since it was introduced in 1994, Thomann's in-house brand Stairville has been a permanent fixture in the store's product range. The brand primarily focuses on the field of stage lighting in general, and its products include spotlights, moving lights, and theatre lighting as well as smoke machines, electronic control systems, and every other accessory you can think of. Thomann constantly has around 1,600 Stairville products on offer, and the figures speak for themselves: Statistically, one in every fifteen Thomann customers owns at least one Stairville product. Incidentally, the name "Stairville" is also a catchy English translation of "Treppendorf", the town that Thomann calls home.
As soon as the devices are fully charged, any number of Stairville BEL4 Battery Event Lights can be used to create an atmospheric lighting effect with one of the pre-programmed colours. Users can charge the units either by setting the power selector on the underside of the housing to mains connection or by simply placing them in the optional touring case. After turning on the device via the power switch located on the bottom of the unit, the menu buttons allow quick navigation to Mode → Static → C-Macro, unlocking nine preset colour mixes for instant ambient illumination. Pro tip: Colour tones that match or complement the wall colour tend to be especially effective. For a discreet lighting setup, the display can be set to Off in the menu, automatically turning off shortly after the last input. The event lights can then be arranged along the walls and angled precisely using the adjustable stand. For added protection during the busiest events, a set of Stairville Rain Cover BEL4 splash guards (sold separately) help shield the fixtures from accidentally spilt drinks. Weighing just 3.6kg, the BEL4 is a great compact lighting solution – not just easy to transport, but also almost effortless to use both as an uplight or an overhead effect.
