7 W (~700 lm): Accent/cove lighting, narrow layered illumination, small rooms (≤10 sqm).
12 W (~1,200 lm): Typical living room or bedroom general lighting when spaced 1.2–1.5 m apart.
18 W (~1,800 lm): Spacious rooms, kitchens, office desks, corridor down‑the‑aisle lighting.
Spacing rule: aim for ~2× depth distance (i.e. 2.4–3.0 m between 12 W downlights in an 8‑ft ceiling for uniform illumination).
6. Installation Notes
Mounting depth: Below ceiling—use frame or spring‑clip type.
Junction box: Prefer fixtures with integrated pluggable driver box (BJC style).
Ventilation: Avoid insulating ceiling materials resting directly atop COB module; allow ≥12 mm vent space.
Orientation: COB must be upright (chip heat-sink above) to prevent driver overheating.
Power Consumption: The light consumes more or less power than the rated 24W.
Brightness (Lumen Output): The actual brightness differs from the specified lumen output.
Color Temperature: The emitted light color deviates from the stated Kelvin rating.
Build Quality: Physical defects or subpar materials used in construction.
Durability: The product fails to meet the claimed lifespan or withstand environmental conditions
