A Practical Guide to Lighting Your Home

Incandescent vs LED Lighting

Incandescent and LED lighting are distinct technologies with unique features, benefits, and drawbacks.

Thomas Edison invented the first commercially viable incandescent light bulb in 1878, and it hasn't undergone any major changes since then. These bulbs produce light by heating a filament until it glows, emitting a warm, yellowish light often associated with a cosy atmosphere.

Despite being the go-to choice for home lighting until the late 2000s, incandescent bulbs are very inefficient and have fallen out of favour, largely replaced by more efficient LED bulbs. While harder to find in stores, incandescent bulbs are still sold online by some retailers.

LEDs, or light-emitting diodes, operate on electroluminescence, emitting light when an electric current passes through semiconductor materials.

LEDs are much more efficient than incandescent bulbs. It's crucial to note that an LED bulb will be significantly brighter than an incandescent bulb of the same wattage. To aid consumers, LED packaging often includes an "equivalent to" wattage figure for comparison.

For complete accuracy, comparing the lumens, or light output, is recommended, although many integrated LED products only list wattage.

Please note that the wattage recommendations used in this article are for incandescent bulbs, so you should look for the "equivalent to" value on any LED bulbs you are considering.

Appropriate Wattage for Room Types

Living Room: For general lighting, you might want around 15-20 watts per square meter (or 1.5-2 watts per square foot). If you have specific task areas like reading corners or workspaces, you may need additional lighting.

Bedroom: Similar to the living room, around 15-20 watts per square meter is a good starting point. Bedrooms often benefit from adjustable lighting options to create a relaxing atmosphere.

Kitchen: Kitchens typically require brighter lighting for cooking and food preparation. Aim for 20-30 watts per square meter, with brighter lights over work areas like countertops and stoves.

Bathroom: Brighter lighting is important in bathrooms for tasks like shaving and applying makeup. Plan for around 20-30 watts per square meter, with additional lighting around mirrors and vanity areas.

Dining Room: A dining room can have similar lighting needs to a living room, with around 15-20 watts per square meter. Consider adjustable lighting options to accommodate different dining occasions.

Home Office: Home offices may require brighter lighting, especially if you do a lot of reading or computer work. Aim for 20-30 watts per square meter, with task lighting focused on your workspace.

Hallways and Entryways: These areas typically don't require as much lighting as rooms where activities are conducted. Around 5-10 watts per square meter may be sufficient, with brighter lighting near entry doors for safety.

Colour Temperature

The colour temperature of lighting can greatly influence the ambiance and functionality of a room. Here's a general guide on which colour temperatures work best for different rooms:

Warm White (2700K - 3000K):

Living Room: Warm white lighting can create a cozy and inviting atmosphere in the living room, perfect for relaxation and socializing with friends and family.

Bedroom: Similarly, warm white lighting is well-suited for the bedroom, as it promotes relaxation and can help create a calming environment conducive to sleep.

Dining Room: Warm white lighting can enhance the warmth and intimacy of dining spaces, making them feel welcoming and comfortable.

Neutral White (3500K - 4100K):

Kitchen: Neutral white lighting is often recommended for kitchens because it provides a balance between warm and cool tones. It can help make tasks like cooking and food preparation easier by providing good visibility without being too harsh.

Home Office: Neutral white lighting is also suitable for home offices, as it offers a crisp and clear light that can help reduce eye strain during tasks that require focus and concentration.

Cool White (5000K - 6500K):

Bathroom: Cool white lighting is commonly used in bathrooms because it provides bright and energizing illumination, which is beneficial for tasks like grooming and applying makeup.

Utility Rooms: Cool white lighting is also suitable for utility rooms like laundry rooms or garages, where bright, functional lighting is essential for completing tasks effectively.

Hallways and Entryways: Cool white lighting can help create a sense of openness and brightness in hallways and entryways, making these areas feel more welcoming and inviting.

It's important to note that personal preferences and specific lighting needs may vary, so feel free to adjust the colour temperature based on your preferences and the intended function of each room. Additionally, dimmable LED bulbs offer flexibility, allowing you to adjust the brightness and colour temperature to suit different activities and moods.
