The most popular and modern bulb seems to be the GU10 LED . The GU index actually shows the type of the socket.
In the past the G sockets were used for all halogen bulbs and because they were very popular and installed in offices, kitchens, living rooms , etc. than the bulb manufacturers quickly replaced them with the new LED technology. GU10 LED is with the same shape as it’s predecessor with some elements responsible of taking the heat away. You have to be very careful when holding these elements, because they are aluminium and could be easily destroyed. All electronics are included in the bulb,so you don’t need any additional transfomer. You can just plug the LED bulb in the socket and that’s it.
Their big advantage is that you can use them in all of your lighting fixtures that you have already installed in your home and are equipped with the GU10 socket. Widely advertised as a 90% energy saving bulbs, I think this statement is sort of overrated. Yes, there is a big difference in power consumption, but not so huge. Anyway, we need to cut down the energy losses as much as possible, so lighting is a good place to start with.
What are the key parameters of GU10 LED bulbs and what you should check before purchasing them.
- First of all you have to request information about the power consumption – there are 3x1W, 6x1W, even 7W – most of the merchants are comparing them to the traditional halogen bulb and usually advertise – Equivalent to …W. This info is very helpful for the customers to calculate energy savings.
- Light temperature – this is so called colour temperature in Kelvins. It is not a real temperature. It shows the colour of the white light. Generally there are two types – Cool white – 4000K and warm white – 2700-3000K. Warm white is the first choice for home interiors as it is closer to the old incandescent bulbs. Cool white is a better solution for offices, working areas and reading zones, because the contrast is higher.
- Beam angle – you can choose between narrow – 12-16 degrees or wide 30-40 degress. If you want to accent the light than narrow is the one you need, but if you need more light distributed around the place than wider is better.
- Lumens – or luminous flux emitted into an area or simply how much light is coming from the bulb – the more the better.
- Average life in hours – showing for how long the effectiveness of the GU10 LED bulb will be at required level. Some are 35 000, while others 50 000 hrs.
- Price – last, but not the least important. You can find big difference in the prices, because the LED bulbs are evolving very fast and new models are available on the market every 5-6 months. I wouldn’t write any info about the current prices as they are not going to be correct even in a month.
The obvious question is: Should I change my old halogen GU10 bulbs with the new, modern, energy saving and high efficient GU10 LED bulbs? The answer is yes, if you are installing a brand new lighting fixture and you are going to buy GU10 bulbs, anyway. But if you are having an old ceiling light for example, with the traditional bulbs, than it is not mandatory to replace them at once. You can change them one by one. I think the LED technology is just getting into speed and more improvements are soon to be developed.
