Union Lighting & Decor: Bulbs

Illuminating Your Space

When it comes to lighting fixtures, selecting the appropriate light bulb can make a significant difference in transforming your space. Whether you're looking for a cozy glow for your living space or a crisp illumination for commercial spaces, these key elements will guide you towards the perfect choise for your lighting needs. To help you make your decision, there are a few key factors to consider: watts, lumens, and kelvins. Let's dive into these factors and explore the different types of bulbs and bases!

Understanding Watts, Lumens, and Kelvins for the Perfect Light Bulb


In the past, wattage indicated the brightness of a bulb, but with the introduction of energy-efficient options like LEDs, this relationship has changed. Watts now primarily represent the amount of energy consumed by the bulb. When choosing a light bulb, look for lower wattage options that still provide the desired brightness. This will help save energy and reduce your electricity bills without compromising on light output.



To determine the brightness of a bulb, pay attention to lumens. Lumens measure the amount of light emitted by the bulb. Generally, the higher the lumen count, the brighter the light. Consider your specific lighting needs when selecting the appropriate lumen level. For instance, higher lumens are suitable for task lighting, while lower lumens create a softer, more ambient atmosphere.


Kelvins indicate the color temperature of a bulb and play a crucial role in creating the desired ambiance. Different color temperatures evoke distinct moods and suit various spaces:   

2,700K -Warm and Cozy: This color temperature creates a warm and inviting atmosphere, ideal for living rooms, kitchens, and bedrooms where you want a comfortable and relaxing feel. 

3,000K - Welcoming and Relaxing: With a slightly cooler tone, this color temperature is perfect for bathrooms, entryways, and outdoor areas. It provides a welcoming and calming ambiance. 

3,500K, 4,000K, 5,000K - Vibrant and Crisp: These color temperatures offer a bright and vibrant light, suitable for commercial/industrial spaces, garages, basements, and workshops where clarity and visibility are important.



Now that we've covered the essential factors, let's consider the various bulb shapes and bases commonly used in North America:   

A (Standard): The most commonly used bulb for household lighting. These bulbs, such as A-19 and A-21, can be used in almost any fixture, providing versatility and widespread availability. 

C (Conical): Cone-shaped bulbs that resemble candlelight. They are often used in chandeliers, adding an elegant touch and creating a cozy, intimate atmosphere. 

G (Globe): Round, full bulbs available in different sizes, depending on the fixture. They are suitable for various applications, from pendant lights to ceiling fixtures, providing a uniform and wide-reaching light. 

T (Tube): Tubular-shaped bulbs that come in a range of sizes. They are commonly used in pendants, wall sconces, chandeliers, and picture lighting, offering focused and directional illumination. 


It's important to keep in mind the type of base your light fixture requires. The two most common screw bases in North America are:  

Standard/Medium Base E26: This is the most frequently used screw base, compatible with many household fixtures and lamps. 

Candelabra Base E12: This smaller screw base is commonly found in chandeliers and decorative light fixtures. 

By understanding the different bulb shapes and bases, you can ensure compatibility with your fixtures and achieve the desired lighting effect.   

In conclusion, choosing the correct light bulb is a vital step in enhancing the ambiance and functionality of your space. By considering factors such as watts, lumens, and kelvins, you can make an informed decision that aligns with your specific lighting needs.

Whether you're seeking a warm and cozy atmosphere for your living room or a vibrant and crisp illumination for commercial spaces, understanding the importance of these key elements will guide you towards the perfect light bulb choice. So, take a moment to assess your requirements, explore the various bulb shapes and bases available, and create a well-lit environment that truly illuminates your life.
