If we decide to change halogen light bulbs to LED bulbs, we neeed to decide whether to change only the bulb or the whole luminaire. If we decide to change only the bulbs, is it better to continue using the G5.3 or MR16 bulbs or switch to the GU10 bulbs? We need to shed light on the options we have when we are going to replace only the light bulbs.
Choosing a colour temperature for the light
Today, LED technology has evolved sufficiently to be cover all hues of white light. LED bulbs can emit both warm white (2800 to 3000 Kelvin) as well as cool white (4500 Kelvin) light. On the contrary, halogen and incandescent bulbs are limited to warm white light temperatures.
Often the information provided for the LED bulb specifically mentions the colour temperature of the bulb.
Why replace halogens with LEDs?
Since 1 September 2018, the production of halogen bulbs has been banned in the European Union and, once the stock of available bulbs has been exhausted, these types of bulbs, which have been so popular in recent years, will no longer be on sale. The time has come to look for an alternative and the most beneficial of them is LED lighting.
LED lighting is very efficient and does not contain substances such as mercury very present in fluorescent low consumption. If we decide to change the halogens for LED keeping the lamp we have two options for the change: MR16 bulbs and GU10.
Replace halogen bulbs with MR16 LEDs
The replacement process is as simple as removing one bulb and putting in the other. But like most easy solutions, it has more drawbacks than advantages.
It is not recommended to conserve 12V transformers when replacing halogens with LED bulbs.
We still depend on the transformer and that consumes energy, generates heat and a light sound that over time is louder, becoming very annoying. At the same time, as the load of the LEDs is much lower than that of the halogens, the new bulbs may not work properly.
Replacing halogens with GU10 LED bulbs
In this case the switch requires a little more work. We need to remove the transformers, replace the lamp holders and install the new energy-saving GU10 bulbs. In this way, we optimise the consumption of the installation as much as possible, completely eliminating hum and ensuring that the new lighting works perfectly.
It should be noted that if we choose the latter option we will have a wider range of bulbs. This will allow us to select the light that best suits our needs.
The GU10 LED lamp is very economical
If what we want is to change linear bulbs, very common for example in floor lamps, such as R7S, we have to look at their length. Unless we also change the lamp holder (if it is possible) we can only use a typical linear light bulb, very common for example in floor lamps, like the R7S.
Unless we also change the lamp holder (if the lamp itself allows it) we can only put bulbs of the same length as the current ones, just as it happens when changing fluorescent tubes for LED ones.
A Valuable Change
If we take into account the difference in consumption of halogens compared to LEDs, the change is already very profitable. Let’s take for example a room with four halogens, the typical 50W, installed. In this case, the consumption of the bulb-transformer set is about 65W, which means 260W in total. We can replace these halogens with 7W GU10 LEDs, which will have similar performance, and reduce consumption up to 28W.
By exchanging 4 50W halogen bulbs for a 7W LED bulb, we can recover the investment in less than 100 days.
If we consider a price per kW of 0.15 € and an ignition of 8 hours a day, the annual saving is 75 € excluding the transformer, if we take it into account the saving amounts to 100 € per year. You can do the calculation using the savings calculator on our website. Moreover, if we consider that the four light bulbs represent a disbursement of just 20€, we recover the investment before the first four months.
There are no more excuses to overpay on your electricity bill. Start enjoying quality, efficient, ecological and noise free lighting by replacing your light bulbs.
