COMPLETED 2023
Three very different lighting problems in one building. The auditorium needs to disappear the moment the house lights fade. The foyer runs from morning coffee to interval crush and has to look good in both. And the façade is a national landmark whose pierced inscription is the most photographed thing in Cardiff Bay — it has to change colour on demand and never look like a light fitting doing it. Regents LED supplied all three: DALI throughout the interiors, DMX512 across the exterior colour layer.
Main Auditorium
Light That Knows When to Leave
An auditorium is the one room where the lighting's most important job is to vanish. Every fitting here is DALI, so the whole house fades as one gesture rather than in circuit steps. RL-LDL1510 gives the ceiling its points of light — a Ø55 aperture with a 15° optic reads as a pinprick in the timber slats rather than a luminaire, and CRI above 90 keeps the wood warm rather than orange. In the balcony soffits, RL-DL3333 uses a super-deep cup and double anti-glare cone; that matters because anyone in the circle below spends two hours looking horizontally at that soffit. The curved balcony fronts and the brick side walls are grazed by RL-ST1330 at 24V — the runs are long and continuous, and on 12V the far end of a balcony would visibly drop off. RL-SW2267 marks the aisle steps at 3W and 15°, enough to make a tread edge readable in a blacked-out house without lifting the ambient level.
Foyer & Bar
Morning Coffee to Interval Crush
This room works at nine in the morning with daylight through the glazing and again at nine at night with a thousand people in it, so the scheme is layered to be dimmed rather than switched. The sweeping suspended loop is the gesture that ties the space together — RL-LIN1200 is the closest catalogue equivalent, its customisable lengths allowing a continuous run rather than a chain of standard modules. Across the raft ceiling, RL-DL1599 handles the general layer; at under 50mm deep it fits a shallow suspended raft with services above, which rules out most downlights before you start. RL-DL1700 covers the rectangular apertures in two- and three-head formats, each head individually aimable, so one fitting lights the circulation route and turns toward the bar face where it is needed. Along the top of the timber bar, RL-ST1226 hides in a shadow gap and grazes the veneer.
Façade & Inscription
Words in the Shell
The entire exterior scheme is built on DMX512 rather than a fixed white composition, because this building changes colour for premières, festivals and national days, and the change has to be programmed rather than re-lamped. RL-E3030 sits behind the pierced inscription — 18 SMD 3030 RGB LEDs per unit, sealed to IP67, each addressable, so the letters can be driven together as one wash or individually as a sequence. RL-IG3901 uplights the entrance colonnade in colour from ground level; beam options from 15° to 120° let a tight graze run the full height of a column, and low-voltage Class III construction is the right answer for fittings set into a public forecourt. RL-BLW provides the concealed colour bands and the glass tower: 5 metres of RGBW in FPCB and silicone, so it bends into a curved reveal instead of needing a straight run.
