Kuala Lumpur, Malaysia
Dynamic RGBW facade lighting turns a landmark Kuala Lumpur bank tower into a programmable DMX light show, powered by ultra-narrow-beam long-throw floodlights.
Set against the Kuala Lumpur skyline beside the KL Tower, this façade lighting project transforms a landmark bank headquarters tower into a fully programmable architectural light show.
The installation uses 54 LN-OFC-130-2-RGBW dual-head floodlights, each combining independent Red, Green, Blue and 3000K warm-white LED channels behind a custom 3-degree large-lens optic. That ultra-narrow beam angle was specified for long-throw precision on a tall facade viewed from a distance, keeping color washes crisp and evenly graduated from base to crown rather than spilling or washing out.
Color control runs on a DMX512/RDM network built around an LTECH LTSA512-1024 controller, 54 WP-804 decoders (one per fixture), DIN-121 signal amplifiers, and a WiFi-RDM01 module for remote addressing and firmware updates — all housed in custom outdoor-rated waterproof enclosures with double-shielded CAT-6 wiring to withstand tropical weather.
The result is a full-facade dynamic lighting system capable of solid color washes and coordinated multi-color sequences, including a red-white-blue-gold display echoing the Malaysian flag captured on site. The project reinforces the tower's presence on the Kuala Lumpur skyline, pairing bank-grade reliability with a striking, code-driven lighting identity.
Products used: LN-OFC-130-2-RGBW dual-head RGBW floodlight ×54; LTECH LTSA512-1024 DMX controller; WP-804 decoders ×54; DIN-121 signal amplifiers ×2; WiFi-RDM01 RDM master control.
Project scale: 54 dual-head RGBW floodlights (108 × 130W emitters, approx. 260W per fixture pair) on a DMX512 control network covering the full building façade.
Every façade at this scale starts with a question: how narrow does the beam need to be, and where exactly should each fixture sit? We modelled the tower in 3D and ran the layout through DIALux evo lighting calculations, testing 15° and 20° optics against the same elevation. The wider washes read well up close but lost definition across a tall, wide façade. That simulation ruled the wide options out early — the delivered batch was built around a custom 3° large-lens optic, with 54 dual-head fixtures positioned column by column before anything was ordered.
The fixtures were built as a custom run rather than drawn from stock. The LED board was designed for this project — 3535 RGBW emitters with separate red, green, blue and 3000K channels rather than one mixed chip, so the warm white sits alongside the colour instead of being approximated by it. Brackets were raised 30 mm and thickened 1 mm to suit the façade's fixing points, and every unit was sealed to IP66 and bench-tested before it left the factory.
Commissioning a façade this tall is mostly patience. One decoder per fixture, signal amplifiers, double-shielded CAT-6 throughout: the DMX512 network was addressed and verified level by level, then each floor's colour and intensity was checked against the building's own stone and glass after dark. Some levels read cooler than others, so the 3000K channel was dialled in floor by floor to even out the wash. The sequences in the gallery below were programmed on site over several weeks, and the system is still being refined as the second phase is planned.
