R40 bulbs are reflector lamps with a diameter of 5 inches (40/8 inches), commonly used in recessed and track lighting to provide wide, soft-edged illumination. They are available in various color temperatures, measured in Kelvin (K), which influence the ambiance and functionality of a space.

2700K (Warm White)

A soft, warm light that resembles the glow of traditional incandescent bulbs. 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. Provides a natural, welcoming warmth without being overly yellow.

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.
