LED GU10 - What You Need To Know
Hi and welcome to light bulb world TV
In this video we’re going to take a look at GU10 LED light bulbs or as they may be more commonly known, spot lights.
These bulbs are found all over the place, from the home, to shops, cafes & restaurants, inside and outside and in a variety of light fittings, like downlights, track lights, garden lights etc.
We’ll be comparing the 50w halogen GU10 which is found in most homes to the latest energy saving LED bulbs from the UK’s leading manufactures, Bell, Sylvania, Osram, BG & Megaman.
When it comes to choosing lights bulbs we’ve been very used to the “bigger is better” philosophy, the higher the wattage the brighter the bulb. Well...that's not the case any-more.
Most LEDs use about 10% of their halogen counterparts whilst producing the same light output, so wattage is no longer an accurate way compare bulbs.
So, if wattage no longer has a bearing on how bright a bulb is; What do we look for?
It’s all about two things; Lumens, and Colour temperature. Lets look at Lumens first:
Lumens are a measure of the amount of light produced by a bulb, the higher the lumens, the brighter the bulb.
To give you an idea, on average a 50w halogen GU10 will produce 350lm, and you can normally achieve this from a 5w LED.
You’ll also need to consider the colour temperature of the bulb. The temperature doesn’t refer to the heat they produce, but the type of light you see, measured in degrees Kelvin but usually known as the k rating. Let's take a look at the difference:
First the Warm White generally varies between 2700K-3000k: this is the equivalent temperature of a standard halogen GU10.
Cool White - 4000K. Good for kitchens and bathrooms, this slightly blue light is great for rooms where a little more detail is required.
Daylight White - 6000K Much brighter than a standard halogen GU10, its wattage can still be as little as 5W, giving much greater perceived light with the same energy saving.
It’s important to note that LED spot lights are available in dimmable and non-dimmable versions and it’s important you decide from the start if you may want to dim your bulbs, if not now but some time in the future. A dimmable bulb can be switched on and off using a conventional light switch, but a non-dimmable bulb can’t be dimmed at all, which means it might be worth spending that little bit extra now to avoid having to change the bulbs later on.
We’ll be taking a closer look at dimming LED GU10s in our next video.
Lastly, and most importantly, we mentioned earlier that these bulbs use a fraction of the energy of a standard halogen bulb. Put simply by switching to LED you’ll save money on your electricity bills.
Using our cost of ownership tool we’re going to take a look at typical kitchen in a 3 bed semi where you’d normally find about 6 spotlights. Comparing 6 x 50w halogens against 6 6w LEDs and running for 4 hours a day.
Based on an average electricity bill (13.5p per kw) the switch to LED will save you over £50 a year, and that's just on one room.
There is a lot to consider when buying LED, but rest assured, the team at Lightbulb World are here to help should you need any assistance.
