Step-by-Step Guide

Step 1: Plan & Measure

Determine the installation path and required length according to the design. Avoid sharp bends during installation (Min. bending diameter > 6cm).

Step 2: Clean the Surface

Clean the mounting surface with alcohol to remove dust and grease, ensuring strong adhesion.

Step 3: Cut & Connect

Cut the strip at the designated cut marks. Use waterproof connectors to connect the power supply, paying attention to the polarity (Red wire is positive, black is negative).

Step 4: Fix & Dissipate Heat

Indoor Dry Area: Peel and stick using the 3M backing. Outdoor/Wet Area: Must be fixed with aluminum profiles and clips for heat dissipation and protection.

Step 5: Controller Debugging

After connecting the power, perform a test. Check RGB colors and the responsiveness of the remote control or APP.

Application Cases

Dynamic ambient lighting in high-end restaurants

Dynamic ambient lighting in high-end restaurants

An upscale restaurant requires lighting that can be adjusted during business hours to create different atmospheres for lunch, dinner, and special events. The lighting needs to enhance the presentation of food while adapting to the ever-changing atmosphere requirements. The HL-R20Q576-CCT-24V fixtures are installed throughout the dining area, providing dynamic ambient lighting with smooth and natural transitions. A color temperature of 3500K during lunch creates a bright and pleasant atmosphere, 3000K during dinner enhances intimacy, and 2700K during special events营造出 a romantic ambiance. Pre-programmed transitions occur automatically throughout the service. The outcomes include an improved dining experience, increased table turnover rate during lunch, higher average customer spending during dinner, and successful event bookings. Dynamic lighting has become a major feature.
