LED Light Bulbs
LED Light Bulbs

LED light bulbs, including smart light bulbs, are a great option for everyday use. These types of light bulbs fit a variety of fixtures. They also use less electricity to produce the same amount of light as incandescent varieties. Their brightness is measured in lumens instead of watts. 


LED light bulbs often require more upfront investment, but they are also more energy-efficient. Made without hazardous ingredients, they are environmentally friendly and have an exceptional lifespan.  


Tip: For sunrooms and indoor herb gardens, try LED grow light bulbs. Use  LED flood lights for backyard patios or front porches and LED night lights for kids’ rooms.

CFL Bulbs
CFL Bulbs

CFL light bulbs usually come in a spiral-shaped design. They emit a softer glow and use minimal amounts of electricity. They contain mercury and can take a while to warm up to full brightness. 


CFL bulbs are usually more budget-friendly than LED bulbs. They can be used in many different fixtures around your home, including indoor lamps and outdoor post lights.

Fluorescent Light Bulbs
Fluorescent Light Bulbs

Ideal for laundry rooms, kitchens and other utility spaces, fluorescent light bulbs use very little energy. They offer optimal brightness and emit a crisp, white glow.  They can last up to 20,000 hours. 


Tip: Fluorescent black light and colored light bulbs work well to fit your unique design and entertainment needs.

Halogen Light Bulbs
Halogen Light Bulbs

Halogen light bulbs are affordable and energy-efficient bulbs. They mimic the warm glow of incandescent lighting. Halogen bulbs are great for indoor and outdoor flood light applications. Unlike CFL bulbs, they don’t need time to warm up. These have a shorter lifespan than other light bulb varieties and usually burn out after 9 to 12 months of regular use.

Incandescent Light Bulbs
Incandescent Light Bulbs

Incandescent light bulbs are widely available and universally accepted inside many homes. They have a significantly shorter lifespan than CFL and LED options. 


Incandescent bulbs are susceptible to temperature changes. They use more energy, but the budget-friendly price point makes them easier to replace. 


Tip: Many appliance light bulbs are also of the incandescent variety, including oven, microwave and refrigerator light bulbs.

Vintage & Decorative Light Bulbs

Vintage light bulbs add a decorative touch to the conventional light fixtures in your home. Also known as Edison light bulbs, they are distinguished by the antique-style filament in the center. These types of light bulbs come in a variety of sizes and shapes.


Other decorative light bulbs include  candelabra bulbs that complement chandeliers, sconces and ceiling fans. Dramatic globe bulbs are great for custom lighting pieces in the den or dining room.

Automotive Bulbs & HID Headlights

Automotive light bulbs come in very specific sizes to match the model of the vehicle. They are available in packs of two. These bulbs were designed to emit bright beams of light for all driving and road conditions. Make sure to look for bulbs that are compliant with the Department of Transportation regulations.   


Tip:  Some higher-end car manufacturers use HID bulbs in place of LED and incandescent headlight bulbs. Check your owner’s manual to verify which works best in your vehicle.

Different types of light bulbs work and look best in different types of light fixures. Some offer energy savings such as LED bulbs. Other such as the common incandescent light bulbs can be easier on the wallet. Decorative bulbs add drama to decorative lighting while function is most important in appliance bulbs.
