Replacing a light bulb might seem simple, but with so many options now available, it can be confusing to know what to choose. The right bulb affects not just how bright a space feels, but also its mood, energy efficiency, and even the way colours appear. Buying bulbs online is convenient and cost-effective, but it helps to understand what you need before you click “add to cart”.
The first thing to check is the bulb base or fitting. Different fixtures require different bases such as screw fittings like E27 or E14, or pin fittings such as GU10, G9, or MR16. If you are unsure, look at the markings on your old bulb or compare its shape and size to product photos online. Taking a clear photo of your existing bulb can also help you match it to the correct replacement.
Brightness is another important factor. Many people still think in watts, but wattage measures energy use rather than light output. Modern bulbs, especially LEDs, are rated by lumens — a higher lumen number means more light. For example, an 8-watt LED can give the same brightness as an old 60-watt incandescent bulb. Checking the lumens will help you choose the right light level without wasting electricity.
Colour temperature determines how warm or cool the light feels. Warm white bulbs around 2700K to 3000K create a cosy, inviting glow ideal for bedrooms and living rooms. Cool white bulbs between 4000K and 5000K feel bright and crisp, perfect for kitchens, bathrooms, and workspaces. Daylight bulbs above 5000K mimic natural light and are great for offices or hobby areas where seeing true colours matters.
LED bulbs are now the best choice for most homes and businesses. They use far less power than traditional incandescent or halogen bulbs and last much longer, saving you money over time. Many LEDs are dimmable, allowing you to adjust light levels without flicker. There are also decorative filament-style LEDs that combine a vintage look with modern efficiency, and smart bulbs that can be controlled from your phone or voice assistant.
Shopping for light bulbs online is easy once you know what to look for. Good online stores list key details such as base type, wattage, lumens, colour temperature, and whether the bulb is dimmable. Many will also include helpful photos and size guides to make sure the bulb fits your fixture. Ordering online means you can stock up without leaving home and often find better prices than in physical stores.
