Surface Mounted LED Downlights for Exposed Ceilings
20 W / 30 W / 40 W / 50 W / 60 W · Ra ≥ 90; Ra ≥ 80 standard, Ra ≥ 90 available
KELVANO surface mounted LED downlights are COB cylinder fittings for ceilings with no void to recess into: concrete soffits, exposed-services and timber ceilings. Two series cover 10 W / 1400 lm compact cylinders up to 60 W / 6600 lm large-format, in white or black, from 2700K to 5000K on the compact series and at 3000K, 4000K or 5000K on the large-format series. Each size is available non-dimming or with Bluetooth (BLE) control for app, remote and wall-panel dimming without control wiring. Orders run from 50 units to full rollouts, and quotations are returned in 24 hours.

Surface mounted or recessed
The choice is made by the ceiling, not the light. Where there is a plasterboard void, a recessed downlight disappears into it. Where there is not, the surface mounted cylinder gives the same downward output from a fitting that sits on the ceiling and reads as part of the interior. Black cylinders on a dark exposed-services ceiling and white on a painted soffit are the usual pairings.
Bluetooth (BLE) control
The Bluetooth (BLE) version puts the control inside the fitting. Fixtures form their own wireless network, so a retail floor or hotel corridor is grouped, dimmed and scene-set from a phone app, a handheld remote or a wall panel, with no control cable run and no DALI bus. For refits and rollouts across an estate, that removes the most expensive part of adding lighting control. Specify Bluetooth (BLE) or non-dimming per SKU on your RFQ.
Applications
- Retail & shop lighting: exposed-ceiling stores and concept retail where the fitting is part of the look, above the 300 lx sales-area minimum.
- Hospitality: restaurants, bars and hotel public areas with concrete or timber ceilings.
- Commercial interiors: offices and circulation in converted and industrial-style buildings at 500 lx.
Why buy surface mounted downlights from KELVANO
Five sizes on one COB platform cover 2.5 m to atrium heights without changing the look. Bluetooth (BLE) is a built-in option on selected series rather than an add-on system, the driver brand is named on your PI, and one manufacturer supplies the surface mounted, recessed and track fittings for a whole interior in one consolidated order under a 5-year warranty.
