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.

A COB down‑light integrates multiple bare LED chips directly onto a thermally efficient module enclosed in an aluminium housing. Unlike SMD LEDs, COB technology offers:
Ultra-smooth, glare‑controlled light (no visible “dots”)
High lumen density in a compact lamp profile (≤ 70 mm depth)
Simplified driver design (only two-wire input)
Generally higher power efficiency (~100 lm/W) and better CRI than cheap SMD options.

I couldn’t find any public catalogue, datasheet, or online product page for Lens Tech India Pvt Ltd—so it’s possible your company doesn’t yet have a digital presence, or the product listings are restricted to internal systems or shared via B2B portals/password-protected zones. To assist further, I’d need any of the following you can provide:
Model numbers or internal codes for your 7 W / 12 W / 18 W COB downlights,
Any PDF catalogue or spec‑sheet, or
Your cut‑out, beam‑angle, and driver/LED brand details.
👉 If you can share even minimal values (“12 W light, 95 mm cut‑out, Bridgelux COB, Fulham driver…”), I can map you precisely into a product‑sort/description grid.
Compact & Efficient Spotlight
“Discover our compact COB downlight (7–12 W) featuring die-cast aluminum housing and precision springs for easy recessed installation. Perfect for spotlighting in kitchens, corridors, galleries, and shops—delivering consistent brightness and sleek aesthetics.”
Based on product descriptions and install guides .
Concise (50–160 characters): Appears fully in search results.
Informative: Highlights energy-efficiency, long life, and installation ease
eam angle & adjustability matter most for accenting — tiltable heads offer great control.
Color temperature: go with 3000 K for warm ambience, 4000 K for neutral, 5000–6000 K for bright task lighting.
Dimmability: Most may not be dimmable unless specified. Choose a dimmable model if needed.
CRI ≥ 90 ensures color-accurate light, important in galleries or retail.
Wattage: 7–20 W is adequate for home/commercial; 50 W used for high-ceiling, expansive lighting
