A Guide to A19, BR30, PAR38, ST19, B10 & Mini Switchable Bulbs
Lighting plays a huge role in how your home feels and functions. Whether you’re curling up with a book, prepping dinner, or hosting guests, the right light can make all the difference. Cree Lighting Home offers a variety of bulb shapes to meet your needs and choosing the right one for the right space can elevate your home's comfort, style, and energy efficiency.
This article will break down which bulb shape works best in each part of your home and why.
A19 Bulbs – The Everyday Hero
Where to Use: Bedrooms, living rooms, table lamps, floor lamps, and ceiling fixtures.
Why It Works:
A19 bulbs are the standard shape most people picture when they think of a light bulb. They offer broad, general-purpose lighting that’s perfect for soft, ambient glow in everyday spaces.
Interior Tip:
Opt for warm white (2700K–3000K) for a cozy feel, or daylight (5000K) in work areas where clarity is important. Dimmable A19 bulbs are a great way to add mood control to your living space.
BR30 Bulbs – The Kitchen’s Best Friend
Where to Use: Kitchens, hallways, and living rooms, especially in recessed lighting.
Why It Works:
The BR30’s wide beam angle (aka “flood” light) makes it ideal for lighting larger areas evenly. It's perfect for overhead lighting where glare-free brightness is essential.
Interior Tip:
Use these in kitchens over countertops to get an even light that reduces shadows while cooking. Choose a brighter temperature (4000K–5000K) for better visibility.
PAR38 Bulbs – The Bold and the Bright
Where to Use: Outdoors (security lighting, porches), garages, basements, or large open spaces indoors.
Why It Works:
PAR38 bulbs are powerful and directional. They’re designed to handle exposure to the elements and often come in weatherproof versions, making them perfect for outdoor fixtures or high-ceiling areas that need targeted brightness.
Interior Tip:
Install in areas that need spotlighting or long-range illumination. Use motion-sensing fixtures for energy savings and added security.
ST19 Bulbs – Vintage Vibes with Modern Performance
Where to Use: Dining rooms, entryways, decorative fixtures, wall sconces.
Why It Works:
ST19 bulbs feature a stylish, elongated vintage filament design. They provide ambient lighting with a nostalgic look, ideal for fixtures where the bulb is visible.
Interior Tip:
Pair with exposed-bulb chandeliers or pendant lights to bring a warm, vintage charm to dining spaces. Use warm white (around 2200K–2700K) to enhance that cozy, nostalgic feel.
B10 Bulbs – Elegant & Understated
Where to Use: Chandeliers, vanity lights, sconces, or accent lighting.
Why It Works:
B10 bulbs are smaller and shaped like a candle flame, adding a touch of elegance. They're best in decorative fixtures where aesthetics matter just as much as function.
Interior Tip:
Use B10 bulbs in your powder room or hallway sconces to add gentle, flattering light. If you’re designing a romantic or cozy space, B10s in soft white are your go-to.
Mini Switchable Bulbs – Small Bulb, Big Flexibility
Where to Use: Smaller lamps, accent fixtures, and tight spaces.
Why It Works:
These compact bulbs are often tunable, letting you switch between multiple color temperatures. That’s perfect for people who want flexibility in a single bulb.
Interior Tip:
Use Mini Switchables in spaces where you want adjustable light throughout the day. For example, a home office where you might prefer bright white light during work hours and a warmer glow in the evening.
