Warm light or white light?
When selecting a bulb to provide a finishing flourish to your room, remember to consider the temperature of its glow. This often comes down to personal preference, but is heavily influenced by use. For example, in a bedroom you might be more inclined to a calming warm light to help you unwind before bed. However, in a room where you need more visibility, cool white may be a more appropriate choice.
Light temperature is measured in Kelvins. For a warmer, yellow light, look out for bulbs with 2,400-3,000 Kelvins. For a bluer glow more alike daylight, opt for a bulb with 4,000-7,000 Kelvins.
Choosing a bulb that casts a warm light will bring a relaxing ambience to your room. Whilst whiter lights work better for providing targeted light.
Bayonet or Edison Screw?
When it comes to bulbs, there are two main types of sockets: Bayonet and Edison Screw.
A Bayonet (B) is defined by two prongs on the base, whilst an Edison (E) features a screw base and is available in a range of sizes.
At Heal's we always include the bulb size in the product name to make it easier for you. The 'standard' Edison bulb size is also known as E27, meaning the fitting measures 27mm in diameter. Other common sizes include E14 and B22. B22 means it's a Bayonet bulb with a 22mm diameter.
Make sure your bulb will fit into your light or it won’t work.
If you're buying a bulb and don't have a ruler handy, use your thumb to measure. An E27 fitting is roughly the same width as your thumb and an E14 fitting is similar to the width of your little finger.
What about wattage?
A major factor when buying a bulb is the wattage of your fixture. The general rule is the higher the wattage the brighter the bulb. Always check your light’s maximum wattage to ensure you don’t cause permanent damage to it by picking a higher wattage bulb.
Wattage isn’t equal from LED to halogen bulbs. An LED bulb with 5W will be brighter than a 20W halogen bulb.
