Reflectors and spot lamps are designed to direct light precisely, making them ideal for highlighting specific areas or objects. They come in various sizes and types to suit different lighting needs. 

R14 

R14 bulbs are small reflector lamps, approximately 1.75 inches in diameter. They are commonly used in display cases, accent lighting, and some track lighting systems where space is limited. 

R16 

Slightly larger than R14, R16 bulbs have a 2-inch diameter. They are suitable for similar applications and provide focused light in compact fixtures. 

R20 

R20 bulbs are 2.5 inches in diameter and are often used in recessed lighting, track lighting, and some outdoor applications. They offer a broader beam compared to R14 and R16, making them versatile for general lighting purposes. 

R30 / BR30 

R30 and BR30 bulbs have a diameter of 3.75 inches. The "BR" stands for "bulged reflector," indicating a slightly different shape that provides a wider beam spread. These bulbs are commonly used in recessed can fixtures and provide soft-edged lighting suitable for general illumination. 

R40 / BR40 

With a diameter of 5 inches, R40 and BR40 bulbs are larger reflector lamps used in high-ceiling areas, large rooms, and some outdoor fixtures. They deliver a wide beam of light, ideal for illuminating expansive spaces. 

BR38 

BR38 bulbs are approximately 4.75 inches in diameter and are often used in outdoor floodlighting and indoor high-ceiling applications. They provide a broad beam of light, suitable for both accent and general lighting. 

Colored 

Colored reflector bulbs, available in various sizes, create ambiance or highlight specific areas with colored light. They are popular in theatrical settings, holiday decorations, and mood lighting. 

Plant Grow 

Plant grow reflector lamps emit light spectra beneficial for plant growth. They are used in indoor gardening and horticultural applications to supplement natural sunlight, promoting healthy plant development. 

Infrared / Heat Lamp 

Infrared or heat lamps are designed to emit infrared radiation, providing heat rather than visible light. They are commonly used in food warming, animal habitats, and therapeutic applications where radiant heat is required.
