Buying Guide
What to consider when selecting LED showcase lighting:
- Display size and shape: Choose flexible or strip-style lights for curved or irregular cases, and strips with adhesive for quick mounting on flat surfaces.
- Brightness and color temperature: 6000K delivers a bright, neutral white suitable for jewelry; consider dimmable options to adjust ambiance.
- Power and installation: Plug-in solutions are fastest to deploy, while peel-and-stick kits reduce installation time but may require surface cleaning for longevity.
- Mounting and durability: UL-listed adapters and robust housings protect against short circuits; ensure mounting hardware fits your case dimensions.
- Maintenance and lifespan: Look for LEDs with long lifespans and stable color output to minimize replacements in display areas.
- Price and scalability: For larger displays, modular kits (multiple bars or 14-foot runs) offer better scalability than single short strips.
