Configure the light before installation
One Commercial Downlight Platform. More Ways to Fit the Project.
The GT Series is a recessed commercial COB downlight designed for projects where lighting decisions can change between specification, sample approval and installation. Independent wattage and colour-temperature selectors let the installer adjust light output and appearance separately—without ordering a different fitting for every combination.
Attention
Stop Locking a Project Into One Output and One Light Colour Too Early
A product schedule may specify one brightness level, while the completed space needs something different. Ceiling height, wall finishes, merchandise, furniture and daylight can all change the result. A fixed-output, fixed-CCT fitting leaves little room to correct the lighting without replacing drivers or ordering another batch.
Reduce SKU Pressure
One configurable product can cover several project conditions, helping distributors and contractors avoid holding a separate stock line for every wattage and colour-temperature combination.
Adjust During Commissioning
Choose a lower or higher wattage after the ceiling layout is installed, then select the preferred warm, neutral or cool appearance independently.
Respond to Design Changes
If the interior palette or task requirement changes before handover, the fixture provides a practical adjustment point instead of forcing a complete fitting change.
Standardise the Visual Language
Five body sizes share a consistent recessed appearance, helping designers keep the same product family across reception areas, retail floors, meeting rooms and circulation zones.
Interest
Two Independent Settings—Not One Compromise
Select the Required Wattage
The illustrated driver offers 18W, 20W and 24W settings. This allows the same fitting to be tuned for different mounting heights, target illuminance levels or energy requirements. Wattage selection changes output and electrical load; it does not force a particular colour temperature.
Select the Required CCT
A second switch selects warm, neutral or cool white. The installer can match the light appearance to timber, stone, merchandise, workplace finishes or brand standards while retaining the chosen wattage.
TRIAC Dimming for Final Scene Adjustment
The constant-current driver is marked for TRIAC dimming, giving the project another layer of control after the wattage and CCT have been selected. Dimmer compatibility, minimum load and dimming range can vary, so we recommend approving the fitting with the intended dimmer before bulk production.
Desire
Choose the Atmosphere Without Changing the Ceiling
Warm white can support hospitality and relaxed lounge areas. Neutral white provides a balanced appearance for retail, reception and mixed-use interiors. Cool white may suit task-led environments that call for a crisper visual impression. Because the setting is chosen independently, the wattage can remain appropriate for the lighting calculation.
Optical control
A Matte Reflector That Blends Into the Ceiling
The deep matte-white reflector softens the visual contrast between the fitting and a white ceiling. The COB source sits above the opening, while the smaller faceted inner reflector controls the useful beam. This makes the luminaire less visually dominant than a bright mirror-finish outer cup.
Four beam angles are available:
- 15°: focused emphasis for feature objects or higher mounting positions.
- 24°: defined accent lighting with slightly broader coverage.
- 36°: a versatile choice for displays, reception counters and general accent lighting.
- 60°: wider coverage for open commercial areas and lower contrast between light pools.
Beam choice should be based on mounting height, spacing and target surface—not wattage alone. Ask for the relevant IES/LDT file or a project lighting calculation before final approval.
Built for commercial use
Thermal Management You Can See
The full die-cast housing uses deep radial fins to increase the heat-dissipation area around the COB module. Stable thermal conditions help the LED and driver operate consistently during long commercial operating hours.
Twin spring clips hold the fitting in the ceiling cut-out, while the external driver remains accessible for connection and configuration. Before ordering, confirm ceiling thickness, clearance above the ceiling, insulation conditions and any local installation requirements.

Where This Downlight Fits Best
Retail & Showrooms
Use different beams to balance product emphasis, circulation lighting and general visibility while keeping one visual fixture family.
Hotels & Reception Areas
Select a warmer appearance for hospitality zones and tune output to suit ceiling height, surface reflectance and the desired ambience.
Offices & Meeting Rooms
Choose a neutral setting and appropriate beam distribution for task areas, collaboration spaces and corridors.
Commercial Refurbishment
Match the GT body size to the available cut-out, then verify ceiling clearance, driver access and the required lighting result.
Action
Approve the Setting Before You Approve the Order
Send us the ceiling height, cut-out, target quantity, preferred beam angle and control requirement. We can help you select a GT size, prepare the correct driver configuration and arrange a sample for dimmer and visual approval.
- Confirm wattage steps and warm/neutral/cool CCT values
- Confirm beam angle and request IES/LDT data
- Check ceiling cut-out, depth and spring-clip fit
- Test the intended TRIAC dimmer with a real sample
- For Australian projects, request the available compliance documents and confirm local importer/responsible-supplier requirements
FAQ
Questions Buyers Usually Ask
Can wattage and colour temperature be adjusted separately?
Yes. The illustrated driver has one selector for 18W/20W/24W and another selector for warm/neutral/cool light. Confirm the supplied selector ranges for the exact model on your quotation.
Does selecting a warmer CCT automatically reduce the wattage?
No. The two settings are independent. Actual lumen output can still vary slightly by LED and CCT configuration, so photometric data should be checked when the project requires a precise result.
Is the downlight dimmable?
The photographed driver is marked TRIAC dimmable. Approve it with the intended dimmer because dimming range and minimum-load behaviour depend on the control combination.
Which beam angle should I choose?
Use 15° or 24° for tighter emphasis, 36° for versatile accent lighting and 60° for wider coverage. Mounting height, spacing and target surface determine the correct choice.
Is this product ready for an Australian project?
Electrical and installation requirements depend on the final configuration and route to market. Request the current model-specific test reports and compliance documents before placing an Australian order; do not rely on documentation for a different product family.
