Our light bulb buying guide will cover everything you need to know about brightness (lumens), energy efficiency (wattage), color temperature (kelvin), color ranking index (CRI), bulb type, bulb styles, and more. The correct light bulb can significantly impact the mood and functionality of a space. Our light bulb guide will help you select the most suitable light bulbs for your needs and room.

Light Bulb Facts: Wattage, Lumens, and More

Choosing the right light bulb involves considering the bulb's brightness, color temperature, energy efficiency, bulb type, and any special features you might need. Several types of light bulbs are available, each with its own characteristics, advantages, and disadvantages. Here are the most common types:

  • Incandescent Bulbs:  

    • Traditional and widely recognized.  

    • Emit warm, soft light.  

    • Inefficient and short lifespan compared to newer technologies.

  • Halogen Bulbs:  

    • A style of incandescent bulb that is filled with halogen gas.  

    • Produce bright and white light.  

    • Slightly more energy-efficient and longer-lasting than standard incandescent lights.  

    • Tend to get very hot to the touch.

  • Compact Fluorescent Lamps (CFLs):

    • Energy-efficient alternatives to incandescent lights.  

    • Takes a moment to reach full brightness.

    • Contains a small amount of mercury, requiring proper disposal.

  • Light Emitting Diodes (LEDs):  

    • Highly energy-efficient and long-lasting.  

    • Available in various color temperatures and styles.  

    • Initially costlier but saves money over their lifespan because of energy savings.

  • Fluorescent Tubes:  

    • Commonly used in offices, garages, and commercial spaces.  

    • Various lengths and color temperatures.  

    • Require ballasts for operation.

  • HID (High-Intensity Discharge) Lamps:

    • Provides high-intensity light over large areas.  

    • Types include mercury vapor, metal halide, and high-pressure sodium lamps.

  • Smart Bulbs:  

    • LED bulbs with built-in technology, such as Wi-Fi or Bluetooth connectivity.  

    • Can be controlled remotely using smartphones or smart home systems.  

    • Some can change colors or brightness levels.

  • Decorative Bulbs:  

    • Designed for aesthetics, often with unique filament designs or shapes.  

    • Used in fixtures where the bulb itself is visible.
