4 Inch Ultra-Thin LED Recessed Ceiling Light 24 Pack - 5CCT Dimmable

In this review the zouzai 24 pack 4 in ultra-thin recessed ceiling lights stands out as a practical choice for homeowners and contractors who need reliable, energy-efficient general lighting. The single biggest reason to buy is the 5CCT reset feature that lets the installer pick between 2700K, 3000K, 3500K, 4000K or 5000K at the junction box, delivering flexible color temperature control without swapping fixtures. The pack offers consistent brightness, long rated life, and simple installation for retrofit and new-construction projects.

Key Features

• 5CCT Reset: The side-mounted selector on the junction box lets you choose 2700K to 5000K to match room tasking or decor without replacing trims.
• Ultra-thin design: The low-profile housing fits into as little as 2 in of ceiling space, making it suited to shallow plenum or joist conditions.
• Dimmable performance: Smooth 5% to 100% dimming is compatible with most dimmers to control ambiance and save energy.
• IC-rated and damp location: Thermal protection allows contact with insulation and safe use in covered outdoor areas like eaves.
• Long life and certifications: Rated for up to 50,000 hours and certified ETL and Energy Star for energy efficiency and safety.
• Quick-connect wiring: UL-approved quick-connect terminals simplify electrical hookup and speed up installation.

Who It's For

This 24 pack is best for homeowners renovating multiple rooms, electricians fitting a whole-house upgrade, or small commercial projects where consistent, energy-efficient downlights are needed. The selectable CCT makes it ideal when different rooms require different color temperatures but need to be sourced from the same product line.

Those who should look elsewhere include buyers who need wet-rated fixtures for direct outdoor exposure or decorative trims with ornate bezels; this product is damp-rated and designed as a can-killer style downlight with a plain white finish and functional focus.
