Lighting Styles - Lamp Lights

The technical team at Lighting Styles get lots of enquiries about LED lighting and what can be used in existing or new fittings. As there is a vast array of LED bulbs available from everywhere such as supermarkets through to retail sheds (many of whom have their own range) it’s sometimes hard to know what you’re buying and whether it’s what you need for your setting.

So while we should all now be saving money on our energy bills many people are finding fault in their newly acquired LED bulbs. Whether it be the light colour, which could be sterile and too cold they’re too dim or seem to lack contrast, we’ve explored the reasons behind this and how you can find the right lighting for your space.

The first thing you need to consider is the lamp power or wattage but with differences in efficiency this isn’t always reliable. One bulb may use half the power as another yet give the same light. You’re therefore going to want to use the lower powered, more efficient bulb because that will save you the most on your energy bills.

Lumens are a measure of the light output while watts show how much energy it uses. So high lumens with low wattage is the target.

Quality of light
This comes down to two things: the colour temperature (measured in kelvins), and the CRI (colour rating Index). The colour temperature determines whether the light will have an orange, white or blue tone. The higher the number the bluer it will appear. A traditional filament lamp produces a warm white light at around 2700 kelvin, while a fluorescent tube designed for use in warehouses may have a cool white 6000 kelvin rating.

LED’s used to get a bad reputation because of this. The first generation had a high colour temperature giving a cool white, sterile light that’s a bit of a contrast to the warm white most people expected to have illuminating the rooms in their homes. Nowadays there’s a big range of colour temperatures available from the filament style - warm white, through a neutral whiter tone, all the way to very cool white.

Finally, we’ll talk about CRI ratings. This is a measurement of how well the full spectrum of colours are shown when using certain light sources. A bulb with a low CRI rating, 70 out of 100 for example, can make usually colourful objects appear less vibrant, flat and lacking contrast. If we want a room to have that vibrant glow we see in interior magazines, a bulb with a high CRI rating is an absolute must.
