Radium’s dimmable E27 portfolio is designed for mains‑voltage replacements in hotels, retail, offices, and residential‑style hospitality. Where GU10 optics aren’t required, these A‑type and globe lamps deliver wide, comfortable light with predictable dimming curves and strong color consistency across batches.
Form factors: A60/A67 general service, decorative ST64/T45 filaments, and G95/G125 globes. Output bands typically span 600–2,400 lm at 6–18 W, depending on glass (clear vs opal) and LED density. Core CCTs: 2200 K (decor), 2700 K (hospitality), 3000 K (retail/office), 4000 K (back‑of‑house). Color quality options include CRI ≥ 90 SKUs for front‑of‑house and visual merchandising.
Filament styles provide near‑omnidirectional 300–320° distribution; opal A‑types deliver softer vertical illuminance and hide point sources in open shades. Large globes need sturdy lampholders—check socket quality on older luminaires.
Practical note: acoustic buzz at very low dim levels almost always points to incompatible wall dimmers or mixed loads; validate on a pilot circuit, then standardize.
Use A60 for guest rooms and small pendants (2.4–2.7 m height), A67 for stairwells and higher ceilings, and globes for visible fixtures in lobbies and dining rooms. Filament ST64 suits boutique retail where the lamp is part of the design; opal A‑types serve back‑of‑house and corridors. In luminaires with sealed shades, pick enclosed‑rated SKUs or reduce wattage to control junction temperature.
On legacy dimming banks, isolate dimmable circuits from non‑dimmable to avoid uneven turn‑down. For AV and camera‑visible spaces, verify flicker metrics (Pst LM/SVM) with the intended dimmer hardware.
These lamps sit naturally alongside Radium GU10 accents and linear luminaires. For scene control, place DALI‑to‑phase or 0–10 V gateways upstream of compatible mains dimmers so housekeeping, evening, and presentation modes are repeatable across rooms. Where glare control is critical, combine opal A‑types with Radium shades and baffles to keep luminance comfortable.
Cross‑category planning helps maintenance: unify on one CCT per zone and two lumen packs (e.g., A60 ~800–1,050 lm; A67 ~1,600–2,400 lm).
Procurement often standardizes two SKUs (2700 K filament + 3000 K opal A67) to cover 90% of rooms while keeping spares lean.
