How to choose a light bulb

An incandescent bulb
Now that we’ve made it through the shortest day of the year and the days are getting longer, I find myself yearning for the light of Spring. Things just seem easier when we are surrounded by light, so brightening up the dark days of winter is still very much on our minds. We depend on artificial light at this time of year, and the type of light we see can really affect our mood. So how do we get it right and make ourselves feel happy instead of glum? It’s all about the type of lighting we choose, and that starts with the humble light bulb.
There are a few things to consider when buying a light bulb - brightness or the amount of light it produces, shape, energy efficiency, and colour temperature. There are so many choices that it can be really confusing, so here’s my quick guide, starting with the types of bulbs available.
A halogen bulb
|We started to think properly about energy efficiency in the early 1980s when Halogen bulbs became popular. The first Halogen lamp was actually invented back in 1882, but it took a little while before they were reliable and bright enough to use! Halogen bulbs were slightly more efficient than the incandescent bulb because they lasted much longer, but they also got much hotter and could be dangerous to handle. We got used to using them in places like kitchen and bathroom ceiling spotlights as they didn’t need changing very often. Again, there weren’t many options if you wanted to use lighting to create a specific mood.|
A twisted CFL bulb
A loop CFL bulb
|The next level energy efficient light bulb was the CFL or Compact Fluorescent Lamp. Again, they were invented surprisingly early, in 1939, but didn’t come into general use until much later on (we’ve obviously been trying to crack this energy efficiency thing for a while). Today they come in lots of shapes and sizes, but in the 1980s and 90s they were a twisted or looped shape and the first ones were quite bulky and heavy. When we got married, my husband and I asked our student friends to buy them as wedding gifts for us as they were relatively expensive. We actually still have some of the bulbs! I remember finding that some of them were so big that they would stick out above a lampshade or light fitting. They weren’t the nicest of things to look at and didn’t really give a soft glow, but if we wanted to save the planet, they were the only option.|
An LED bulb with a tungsten look
|Concerns about how to dispose of CFL bulbs (they contained mercury) and the expense of production slowly led to a shift towards LED bulbs. Light Emitting Diodes or LEDs were again invented a surprisingly long time ago - 1907 to be exact, but it took a good few decades before the bulbs were cost effective enough to be produced commercially. They are now the most energy efficient light bulbs on the market and are almost a standard choice for manufacturers and homeowners because they come in many different shapes, sizes and colours.
So, where does that leave you if you need to buy a new light bulb? Chances are you’re probably going to buy an LED, because of their efficiency and the huge range of styles available. The next question is usually, how do I know how bright it will be? We all used to understand brightness in terms of wattage as there weren’t many options and you could easily see the differences between a 40 watt bulb compared to a 60 watt bulb.
The answer is to look at the Lumens, which is a measure of brightness. The great thing about using Lumens to compare brightness is that it applies to all types of bulb, no matter what technology is inside the bulb. Once we know the amount of Lumens we need, it makes it all much simpler. Here’s a handy conversion chart, which I still find myself referring to:
|A lumens chart from The Light Bulb Company|
Okay, so now we know which type of bulb to buy and how much light we need it to give us. The next thing to consider is the colour temperature. Think of the colour difference between bright morning light and a pinky sunset. The blue light of the morning sky will make us feel awake and energised, whilst the pinky soft glow of the sunset will make us feel relaxed. It’s the same with bulbs. Do you need a bright, cooler light for say over the bathroom sink (so you can see what you’re doing), or do you need a warmer, softer glow for the lamp in the living room? That’s the colour temperature.

|Colour temperature is measured in Kelvin, named after Lord Kelvin who came up with the measurement. Basically, the lower the Kelvin number is, the warmer or more yellow/orange the light will be, and the higher the number, the cooler or more blue the light will be. Here’s another handy chart to help you buy the right colour:|

There is one final thing to consider when buying bulbs, which touches on lighting design. The direction and spread of the light you get from your bulb will give you different effects which can be used around your home. The type of light fixture you use will generally determine how this happens, as some shades will concentrate the light in a particular direction, and others will help it to spread around the room. For example, a desk lamp will give you a smaller, more targeted light (perfect for working at a computer or reading with). A lampshade will give a wider spread of light coming from the top and bottom of the shade. The light will be softened or diffused by the fabric, making it perfect for use in the evening when you’re watching TV and want to relax.

If you're anything like me you'll have a mixture of all sorts of bulbs in your home, some old, some new, and some of them not quite doing the job you want them to. But at least now when you need to replace one, you'll know where to start.

Dulux colour of the year - Bright Skies
29 Sep 2021
So, Dulux have announced their colour of the year for next year, and here it is! Bright Skies is described as the 'breath of fresh air' that we all need after being indoors for so long. What do you think? I'm reserving judgement at the moment. It looks a little cold in the picture, but I don't think the beige sofa and the styling are doing it any favours here. Maybe colour drenched (painted on walls, ceilings, trims and doors) and with some warmer burgundies and terracotta, it could be lovely. You can buy the colour here.
A new home collection from Paloma Faith
28 Aug 2021
|British singer songwriter Paloma Faith has recently launched her first collection for the home.

It's all about soft yellows
28 Jul 2021
|I was watching an Instagram live post from The Little Greene Paint Company last week, and they were discussing a comeback for yellow. Now, as you know, I don't think you have to follow the trends but yellow hasn't been fashionable for a long time, so this sunny, uplifting shade is often overlooked. A warm yellow like Little Green's Carys (above) is perfect for cheering us all up, and you can buy it here.|

Wallpaper made of cork?
29 Oct 2019
|Sustainability and concern for our environment are key in the interiors world right now (as they should be). So when I saw that Monkey Puzzle Tree (a brand I admire for their sense of style and creativity) had produced this wallpaper made of cork, I was blown away. Cork is great for so many reasons - it can be harvested every nine years without harming the tree, is grown without the need for pesticides or fertilisers, has excellent sound and heat insulation properties, and is naturally antimicrobial and antifungal. This wallpaper has an A+ rating for emissions so it creates a healthy environment wherever it is hung. Add to this that the design was produced in collaboration with the talented Drew Millward who lives in my home county of West Yorkshire, and that it's called 'Hit The North', I was bound to fall in love with it. You can buy the wallpaper here.|

My kitchen project featured on the Artifact Lighting blog!
1 Aug 2019
When I designed the contemporary copper kitchen, I wanted to use some copper elements to add warmth and also to tone in with the pink walls and pale grey units. I found these pendant lights from a company called Artifact Lighting, and they are perfect because they add to the 'warm glow' I wanted to acheive. They also have a vintage look which contrasts nicely with the sleek look of the kitchen units. When the kitchen was finished I sent some pictures to Artifact Lighting, and they liked the kitchen so much they featured it on the blog page of their website.

Sustainability in furniture design
7 May 2019
|Sustainability is something that is becoming more and more important in interior design - not just where we buy items from and how far they've travelled to get to us, but also the materials that they are made from. Kartell, one of Italy's best known design brands, have just released the world's first piece of furniture made from a bioplastic called Bio-On. It's a fully sustainable version of one of their best selling items - the Componibili modular unit, and it comes in four delicious pastel shades. They may be 100% sustainable, but they are also super cute and bang on trend with this seasons colours. You can buy them here|
The latest trend in shutters

Forget painted shutters - the new style direction for window shutters is bare wood. These full height shutters made from sustainably sourced ash are the newest product from California Shutters, and are set to be big this year.
My new favourite tile!
7 Feb 2019
I was searching for some tiles for a client's splashback recently and came across these beauties from Topps Tiles. There's long been a trend for patterned tiles, with lots of geometric shapes and bold colours going on, but I've begun to see more and more tiles with a pattern in the surface of the tile itself. These ones are a lovely example, and the deep blue colour is just stunning. To get a closer look at them, follow the link below.
Pantone announce their colour of the year 2019
11 Dec 2018
Leading colour experts Pantone have annouced the shade which they think will be the colour of the year for next year - Coral pink. It might look very bright and scary, but it's actually quite easy to use. I wouldn't suggest painting a whole room in it, as that might be a bit overwhelming, but I would use it in small doses, such as on cushions or in artwork, to liven up a shceme. Pantone say that the colour is meant to 'embrace us with warmth and nourishment and provide comfort and bouyancy in our continually shifting envirnoment', which basically means it's a happy, uplifting colour, and might just cheer us all up!
My work featured on Homify
8 Oct 2018
My work has been featured in an article on Homify - one of the leading online ideas platforms for all things interiors. My project is in an article on how to avoid common mistakes when designing a bedroom. The article mentions how important it is to block out light for a good nights sleep - something I addressed by adding blackout lining to the curtains and adding an extra layer of window dressing with the wooden Venetian blinds. To see the article, please use the link below.
