The backlit LED structure directs light straight downwards through an optimized optical lens. This provides a more uniform distribution of light across the 120° wide beam angle, mitigating localized dark spots or yellowing over time. Delivering an impressive output of 1620 lumens, this 18W square downlight provides unparalleled brightness while consuming up to 85% less energy than outdated fluorescent ceiling bulbs.  
 

With a physical dimension of 176mm × 176mm and a standard 6-inch cutting hole dimension (140mm to 150mm), upgrading your existing lighting setup is completely hassle-free. The robust spring clips secure the fixture firmly against the plaster board ceiling, ensuring no unsightly gaps. Its sleek, minimalist square frame blends flawlessly into contemporary interior architectures.
 

Lighting completely transforms the mood of a room. The BSLight BS-1080S/18W is available in three distinct Color Temperatures (CCT) to fit your exact lifestyle needs:

Q1: What is the cutting hole size for a 6-inch square LED downlight?
A:For the BSLight 6-inch square 18W downlight (BS-1080S/18W), the required ceiling cutting hole dimension is between 140mm to 150mm. Always measure your plaster ceiling cutout before purchasing to ensure a flush fit.

Q2: Is the BSLight 18W LED downlight SIRIM approved in Malaysia?
A:Yes, the BSLight BS-1080S/18W recessed downlight is fully SIRIM certified. This guarantees compliance with local electrical safety regulations, making it highly secure against short-circuit or overheating hazards.

Q3: What does DOB mean in LED lighting, and what are its benefits?
A:DOB stands for Driver-on-Board. It means the electronic driver is integrated directly onto the LED chip board instead of using an external plastic driver box. The benefits include a slimmer light design, fewer wire failure points, and a longer operational lifespan.

Q4: How bright is an 18W LED downlight in lumens?
A:The BSLight 18W square downlight outputs 1620 lumens, providing a brilliant and crisp light distribution. It easily replaces old 30W–40W fluorescent downlights while consuming far less electricity.

Q5: What is the difference between 3000K, 4000K, and 6500K color temperatures?
A:3000K (Warm White) produces a relaxing yellowish light; 4000K (Cool White) offers a neutral, slightly warm bright light ideal for tasks; 6500K (Daylight) gives a bright bluish-white light that maximizes visibility.

Q6: Can I install this IP20-rated downlight in the bathroom?
A:The IP20 rating means it is designed for indoor dry zones. It is perfectly fine for bathroom ceilings provided it is placed outside the direct shower splash zone and the room is well-ventilated to prevent moisture buildup.

Q7: What does a CRI >80 mean for this ceiling light？
A:CRI stands for Color Rendering Index. A CRI higher than 80 means the light renders colors accurately and naturally, close to how they appear under true sunlight. It prevents rooms from looking dull or washed out.

Q8: Why should I choose a backlit LED downlight over an edge-lit panel?
A:Backlit downlights project light directly downward from the back of the chassis. They offer higher lumen efficiency, better heat dissipation, and are far less prone to dark spots or yellowing patches over time compared to edge-lit alternatives.

Q9: What is the thickness of the BSLight 6" square downlight?
A:It has an ultra-low profile thickness of just 25mm, making it exceptionally easy to install in shallow plaster ceilings where vertical spacing is tightly restricted.

Q10: Can this square LED downlight replace my old round downlight?
A:Yes, you can replace a round downlight with a square downlight, provided your current ceiling cutout hole falls within the 140mm to 150mm range. The square outer frame (176mm) will neatly conceal the circular cutout beneath it.
