A four step guide to replacing light bulbs in the home

Upgrading lightbulbs to LEDs or CFLs is one of the easiest ways to save energy in the home and reduce your bills.  However, with more lighting products and technologies on the market than ever before, and a host of other aspects such as lighting brightness, ambience and compatibility to also consider, replacing light bulbs in the home can sometimes appear problematic.

PremiumLight's 4-step guide breaks this process down to make sure that when replacing or upgrading home lighting, you can find the right bulb for the right room to create the desired look and feel whilst ensuring you have purchased a long lasting bulb that is energy-efficient and cost-effective to run. Simply follow the links along the top to of your screen or in the drop down tab for all the information you'll need.

Step 1: Type & Location

Consider where in the home or for what room are you buying a light bulb for? Why do you need light in there? What is the light for? Lighting a room or area appropriately is important, and thinking about your aims for your lighting will help you determine what light bulb to buy.


Living Room and Bedroom

Main ceiling bulbs for the living room, bedrooms and dining rooms need to provide enough light and create the ambience you are looking for.  PremiumLight recommends LEDs as the best choice for replacing old incandescent or halogen bulbs.  CFL bulbs make a good secondary choice - these have a cheaper purchasing price and a good quality CFL can last for up to 15 years.

Kitchen and dining room

Spotlights are a popular choice for kitchens and dning rooms, and again LEDs come up trumps.  A ceiling of ten switched-on 50W halogen downlighters is drawing a colossal 500W of power - huge cost saving can be made by upgrading to quality LED bulbs.  If your spotlights work with a dimmer, some LED bulbs can perform this function, but it's very important to check whether the new bulb is compatible with your existing fittings, as it may be necessary to replace the luminaire as well.  Your lighting retailer should be able to advise you on this.

PremiumLight does not recommend halogen bulbs.  Even the more efficient halogens on the market, that achieve a C-rating, will cost you much more than an LED in the long term.  A typical C-rated halogen spot might consume 30-35W - see the table below for the cost savings you could make.  From September 2013, D-rated halogen bulbs can no longer be placed on the market.

Bathroom, garage and storage room

In some rooms a large amount of light is needed, but they may be used less frequently, for example bathrooms and garages.  A Fluorescent Tube is a good choice here, where the instant full brightness of an LED may be less important.

The figure below shows typical lighting requirements for different rooms at home and light bulbs that will best suit them:

Replacing a halogen with an LED

While the initial outlay on LEDs is higher, replacing 4 halogen spots with LEDs over 10 years would save around £150, generate 12 fewer waste bulbs and use 980 kWh less energy.
