PAR38 LED Light Bulbs
Why Use PAR38 LED Flood Light Bulbs?
The PAR38 bulb is a popular choice for both indoor and outdoor applications that require powerful, directional lighting. Thanks to LED technology, today’s PAR38 LED bulbs are significantly more energy-efficient and longer-lasting than their incandescent and halogen predecessors. On average, each flood light bulb in this category can last up to 50,000 hours, reducing replacement frequency and energy costs.
A PAR 38 bulb measures approximately 4.75 inches in diameter and is typically used in recessed cans, track lighting, and landscape fixtures. For outdoor use, make sure to select PAR38 bulbs rated for wet locations or enclosed fixtures by checking the Safety Rating in the product’s specification tab.

Beam Angle Options for PAR38 Flood Light Bulbs
Choose your beam spread based on the desired light distribution:
- Narrow Spot (<10°): Focused beam for highlighting objects
- Spot (15°): Ideal for accent lighting
- Narrow Flood (25°): Balanced beam for artwork or architectural features
- Flood (36°): Great for general lighting in rooms or outdoor areas

Color Temperature Guide
PAR38 LED flood lights are available in a range of color temperatures, measured in Kelvin (K):
- 2700K – Warm White: Soft, yellowish glow similar to incandescent lighting
- 3000K–3500K – Halogen-like: Clean, neutral light for living rooms or retail
- 4000K–5000K – Cool White/Daylight: Brighter, whiter light ideal for task lighting, security, and commercial use
The higher the Kelvin, the cooler and more bluish the light will appear. The lower the Kelvin, the warmer and softer the glow.
What Is High CRI Lighting?
CRI (Color Rendering Index) measures how accurately a light source reveals colors compared to natural sunlight. A high CRI (90+) PAR38 bulb ensures colors appear vibrant and true, which is especially important in retail, galleries, and photography setups. While most homeowners may not notice a drastic difference, high CRI bulbs can enhance the overall aesthetic and clarity of your space.
Frequently Asked Questions (FAQs)
What is a PAR38 bulb?
A PAR38 bulb is a type of directional flood light bulb with a 4.75" diameter. It is commonly used in outdoor flood lights, recessed cans, and track lighting. “PAR” stands for Parabolic Aluminized Reflector, which helps focus and direct the beam of light.
What is the difference between PAR20 and PAR38 bulbs?
The difference lies in size and light output. A PAR20 bulb is smaller (2.5" diameter) and typically used for accent lighting or small fixtures. A PAR38 bulb is larger and brighter, making it better suited for flood lighting, high ceilings, and outdoor use.
