It is now common response of everyone that “switch to LED Lighting” because led technology has a lot of advantages, but when you want to take the plunge, several questions arise: what should I expect? Which bulbs to choose? How much does it cost?
Switching to LED lighting, advantages and disadvantages
The advantages are more numerous than the disadvantages:
- Energy saving.
- Financial savings, up to 90% savings compared to any other lighting.
- Simplicity, bulb change is less common given the life of LED bulbs.
- Robustness, LED bulbs are less afraid of shocks.
- Eco-friendly, LED bulbs do not contain mercury and are recyclable as non-hazardous waste.
- It is necessary to pay attention to the chosen bulbs, the standard NF EN 62612 is to be respected for the protection of the eyes against the blue lights which diffuse in excessive quantity certain ampoules.
- The implementation of LED lighting can represent an investment, but quickly profitable.
Switch to LED lighting, what to expect
Here’s what you need to pay attention to before you start, these elements will save you time and estimate the total cost of switching to LED lighting.
The voltage of your current lighting
Are your bulbs in 12V or 220V? Look at the caps, if you see two small metal plugs they are bulbs 12V, GU53. If they are two pins (base says “bayonet”) then it is 220V bulbs, GU10.
Is there a transformer (which converts the intensity from 220V to 12V)? If so, is it central (attached to several bulbs) or each bulb has its transformer? You can choose bulbs of 12V or 220V but if you replace your bulbs 220V by 12V it will be necessary to provide an individual transformer with the new bulbs.
The quality of the bulb
As mentioned above some bulbs emit more or less blue light considered harmful to health too much, especially when the bulb is at a distance relatively close to your eyes. Prefer a quality bulb, perhaps more expensive but of better quality.
Number of bulbs per piece
Depending on the room of the house a Lux number (unit of measurement) is recommended:
- Staircase 50 lux
- Closet 30 lux
- Toilets 200 lux
- Kitchen 300 lux
- Entrance hall 100 lux
- Room 200 lux or more as required
- Dining room 300 lux or more if needed
- Salon 300 lux or more as needed
- Office 400 to 500 lux
Here is a simple calculation to use to know how many LEDs you need:
On your bulbs is indicated the luminous flux (Lumen). Divide the number of Lumens by the number of m2 of the room to obtain the Lux which helps you to understand why switch to LED Lighting. Finally, divide the number of Lux recommended by the number of lux provided by your bulb, you get the number of lamps to provide for the room in question.
Example: Bulb 621 Lumen, living room of 25m2
621 Lumen / 25m2 = 24.84 Lux
300 Lux (recommended for a salon) / 24.84 Lux = 12.07 or 12 bulbs
Hot or cold atmosphere?
Depending on the room there so you can choose a rather warm (yellow) or rather cold (white). Generally prefer warm white bulbs for a warmer atmosphere (living room, living room, bedroom, etc.). You can opt for a cold light, a cool white for rooms such as garage and cellar.
Some bulbs and transformers will be adapted to intensity variations. Generally more expensive, if you want to be able to vary the intensity of your light remember to check the compatibility with your bulbs and your possible transformer.
LED strips and rulers
You can decorate your furniture, your kitchen or your alcoves with LED ribbons. Relatively easy to install, you will need a transformer (low voltage device) and a plug on mains or with dominoes.
