4 Inch round downlight retrofit kits are a popular choice for upgrading to energy-efficient LED lighting. They provide bright, even light and are perfect for many spaces like living rooms, kitchens, and offices. Easy to install, these lights fit standard fixtures and add a clean, modern touch to any room. Their size makes them versatile for both residential and commercial use.

CCT Selectable/Tunable

These downlights let you adjust the color of the light to match your needs. You can choose between warm light (2700K) for a cozy feel or cool light (5000K) for a bright and focused environment. For example, the ASD LED Square Downlight lets you easily switch between these settings, making it perfect for homes and businesses.

2700K (Warm White)

This light emits a soft, warm glow that resembles the glow of traditional incandescent bulbs. It is ideal for creating a cozy, inviting atmosphere in living rooms, bedrooms, and dining areas. It emits a yellowish hue that promotes relaxation and comfort.

3000K (Warm White)

Slightly brighter than 2700K but still maintaining a soft, warm tone. Commonly used in kitchens, bathrooms, and accent lighting where a gentle yet more functional ambiance is desired. It provides a natural, welcoming warmth without being overly yellow.

3500K (Neutral White)

A balanced white light with a more neutral tone that avoids the yellow of warmer temperatures. Perfect for spaces where clarity and focus are important, such as offices, retail environments, or kitchens. It provides good visibility while maintaining a comfortable ambiance.

4000K (Cool White)

This color temperature is often associated with office and commercial environments. It offers a crisp, clean light that promotes focus and productivity. It is suitable for workspaces, garages, or hallways where bright, functional light is necessary without being harsh.

5000K (Daylight)

A bright, white light that closely mimics natural daylight, providing excellent color rendering and clarity. Ideal for areas where true-to-life color appearance is important, such as in art studios, kitchens, or task lighting. It also creates an energetic, awake atmosphere, making it ideal for areas where alertness is key.
