Choosing the right light bulbs for your home might seem simple, but with the variety of options available today, it can quickly become confusing. From the latest energy-saving technologies to understanding lumens and colour temperature, this guide will help you pick the best lighting for every room in your home.
- Types of Light Bulbs: What Are Your Options?
Let’s start with the different types of light bulbs you can choose from. The four main categories are:
- Incandescent Bulbs: These are the traditional light bulbs most of us grew up with. They emit a warm, cosy glow but aren’t energy-efficient and have a shorter lifespan compared to other options. These bulbs are being phased out but you may still have one lurking in the back of a cupboard somewhere!
- LED Bulbs (Light Emitting Diodes): The most energy-efficient choice on the market. LED bulbs use much less electricity and last up to 25 times longer than incandescent bulbs. They’re available in a wide range of brightness and colour temperatures (more on that below).
- CFL Bulbs (Compact Fluorescent Lamps): These use less energy than incandescent bulbs and last longer, but they don’t perform as well as LEDs. Some original models of CFLs can take a little time to reach full brightness.
- Halogen Bulbs: A more efficient version of incandescent bulbs, halogen bulbs are brighter but still not as energy-saving as LEDs. They provide a crisp, white light and are often used for spotlights or task lighting.
- Understanding Lumens: How Bright Is Your Light?
Instead of thinking about bulbs in terms of watts (which measure energy usage), the more important measurement for brightness is lumens. Lumens tell you how much light a bulb produces.
- A higher number of lumens means a brighter light. For example:
- 400 lumens = dim light (perfect for ambient lighting in living rooms or bedrooms)
- 800 lumens = standard brightness (good for general use in kitchens, bathrooms, or hallways)
- 1600 lumens = bright light (ideal for task lighting or large, open areas)
For context, a typical old style 60-watt incandescent bulb produces around 800 lumens.
- Colour Temperature: Kelvin Makes a Difference
The colour of the light a bulb gives off is measured in Kelvin (K). This refers to the warmth or coolness of the light. Here’s a quick guide:
- Warm White (2700K – 3000K): This light has a yellowish tone, similar to traditional incandescent bulbs, and is perfect for creating a cosy, inviting atmosphere in living rooms, bedrooms, and dining areas.
- Cool White (3500K – 4100K): This light is brighter and crisper, ideal for kitchens, bathrooms, and workspaces where you need more clarity.
- Daylight (5000K – 6500K): Daylight bulbs emit a blue-white light that mimics natural sunlight. They’re excellent for reading, task lighting, or rooms that don’t get much natural light.
The higher the Kelvin, the cooler the light. Think about where you're using the bulb and what kind of light you might prefer in that area.
- Energy Efficiency: Why It Matters
LEDs are by far the most energy-efficient option, using up to 90% less energy than incandescent bulbs. While they may cost a bit more upfront, their long lifespan (up to 25,000 hours or more) means they save you money over time on both energy bills and replacements.
Look out for the energy rating label on the bulb packaging, this will help to identify the most energy efficient bulb for your type of lamp or fitting.

- Dimmable and Smart Bulbs: Customising Your Light
If you want more control over your lighting, consider dimmable bulbs. These allow you to adjust the brightness to suit your mood or needs, whether you're relaxing in the evening or need focused light for a task.
Smart bulbs take it a step further, letting you control your lights from your smartphone or even with voice commands via home assistants like Alexa or Google Home. Some smart bulbs also let you change the colour of the light to suit different occasions.
Final Thoughts
Whether you’re looking to create a cosy ambiance or need bright task lighting, choosing the right bulbs for your home comes down to understanding lumens, Kelvin, and the type of bulb that fits your needs. LED bulbs are a great all-rounder for energy efficiency and longevity, but don’t forget about the warmth and style that incandescent and halogen bulbs can bring to certain spaces.
Now that you’ve got the basics, you can confidently light up every room in your home!
