Manufactured by: Lens Tech India Pvt. Ltd.
The Delta Series is a high-performance architectural spotlight designed for those who require maximum brightness and visual comfort. Engineered with High-Lumen LED chips and precision optics, the Delta model delivers a powerful, uniform beam, making it the industry standard for premium retail, commercial, and residential focus lighting.
Key Technical Highlights:
Superior Brightness: Features High-Lumen LED Chips (up to 120-140 Lm/W) for intense, crisp illumination that outperforms standard COBs.
Eye-Health Technology: 100% Flicker-Free driver ensures a steady light output, preventing eye strain and making it ideal for high-definition photography/videography.
Maximum Safety: Equipped with an HPF (High Power Factor) Isolated Driver, providing advanced surge protection and electrical isolation for long-term durability.
Thermal Excellence: Heavy-duty Die-Cast Aluminum housing with an integrated heat sink to maintain optimal chip temperature and prevent lumen depreciation.
Premium Finishes: Available in sleek Black or White bodies with multiple reflector options (Rose Gold, Silver, Chrome).
Best For: High-end showrooms, art galleries, luxury residences, and offices where light quality and electrical reliability are critical.
MATERIAL SPECIFICATION
MATERIAL SPECIFICATION
MATERIAL SPECIFICATION
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.
