3. Twice the Brightness
   The larger chip area produces higher luminous flux, resulting in brighter, more uniform illumination across the strip.

4. Superior Heat Dissipation
   Enhanced chip structure and larger contact surface improve heat conduction efficiency, effectively reducing temperature rise and extending performance stability.

5. Reliable Sanan Chip Technology
   Uses high-quality Sanan LED chips known for consistent color temperature, efficiency, and long-term reliability.

How It Works — Color Temperature Control

Our CCT Adjustable COB LED Strip allows users to easily switch between three color temperatures — 2700K / 4500K / 6500K — using a simple wall switch, with no extra controller required. The wiring configuration determines the default color temperature when powered on.

① Wiring Option 1: C+ & W- Connection

• Default Color Temperature: 2700K (Warm White)

• Switch Sequence:
  1️⃣ Turn on → 2700K (Warm White)
  2️⃣ Toggle once → 6500K (Cool White)
  3️⃣ Toggle again → 4500K (Neutral White)

• Ideal for residential or decorative lighting where warm tones are preferred.

② Wiring Option 2: C− & W+ Connection

• Default Color Temperature: 6500K (Cool White)

• Switch Sequence:
  1️⃣ Turn on → 6500K (Cool White)
  2️⃣ Toggle once → 2700K (Warm White)
  3️⃣ Toggle again → 4500K (Neutral White)

• Suitable for offices, retail spaces, and industrial environments requiring bright, cool illumination.
