Energy efficiency is about making the best possible use of the input energy when transforming it into output energy. French chemist Antoine Lavoisier(1743 to 1794) stated that, “Nothing is lost, nothing is created, everything is transformed.” Energy is transformed from one state to another and is not lost. It’s during the transformation process tha...
A 50 watt halogen GU10 lamp transfers only 10% of energy into light, the remaining 90% is transferred into heat making it a grossly inefficient light source, which is why it's been banned. This diagram shows how the input energy is distributed or transferred. While LED lamps will also transfer some energy into heat, let's say 10%, they are 90% ener...
The 50 watt halogen GU10 emitted around 400 lumens, back in the days of the incandescent era everyone just ordered light bulbs by their wattage. It was only when LEDs became available that lumens become the more important factor. Lumens are the units that we measure brightness in. Most 5 watt or 6 watt GU10 LED lamps on the market emit around 400 t...
Lighting accounts for around 15% of the average household's electricity costs, so there are other areas in your home that you can look to reduce energy consumption such as heating and general electrical items like the dishwasher or fridge. If you've not already made the complete switch to LED, then now is certainly the time. If you've got one room ...
Adding a dimmer switch to the circuit further reduces energy and increases lamp life. Smart lighting systems such as Lightwave gives you even more control as you can set timers and control all of your lights (and other electrical equipment) from your smartphone. The Lightwave App also shows you how much energy each smart switch, smart socket or hea...
When energy labels first started to appear on lighting products in 2012, they were a bit of joke as they had no scalability. LEDs had already reached an A+ rating, which meant any further improvements would become A+++++++, making the whole system seem ridiculous. In 2021 the system got redesigned downgrading a light source with a seemingly healthy...
With the current energy labeling system in mind there are only a few A-rated lamps available, these are going to be the most energy efficient. Like usual, Philips Lighting have been the fastest to produce them and have a few choices available in the filament or GLS (General Lighting Service) shape. Here they are, in order of the most energy efficie...
Instead, if you’re buying a new fridge or TV or other appliance, the best way to judge its energy efficiency is the label. Those rated A or above are the most efficient for their size. To compare between differently sized appliances, energy labels also now print suggested kWh usage per annum for each appliance.
According to one data on Statista, if you replace one 60-watt bulb with a 10-watt LED bulb in the UK, you can save €8.83 or £7.81 annually. In other places such as Denmark and Germany, the annual savings were as much as €15 or £13.27. Now, this figure does not look like a lot.
Our calculator provides you with your annual cost saving, and how long it will take for you to make your money back on the cost of the lamps, as well as calculating more than one lamp type at a time, allowing you to get results for your entire project / household.
