In this section, we'll attempt to answer your most frequent concerns when lighting your home or business.
Can I use LED bulbs in the same supports as old-style bulbs?
LED light fittings are manufactured to directly substitute traditional bulbs, using the same connectors. Consequently, they can be directly substituted in most cases.
What are lumens and what is their equivalent in Watts?
The lumen is the international measurement for the quantity of visible light emitted by a light source.In other words, it quantifies the total quantity of light coming out of the light point.For example, an 80W incandescent bulb provides 800 lumens while an LED bulb with the same consumption can produce up to 7200 lumens.
What is CRI?
The Colour Rendering Index (CRI) is a unit measuring the capacity of a light source to reliably reproduce objects' colours compared to an ideal light source, or natural source such as sunlight.The CRI is determined by a value from 0 to 100, where 100 is the perfect value.
Depending on the CRI obtained, we might expect the following reproduction reliability based on the colour temperature:
What standard should be applied if Light Emitting Diodes (LEDs) are used as a light source?
National legislation does not mention LEDs.It simply requires minimum levels of lighting, independently of the chosen light source.
What is colour temperature?
Colour temperature refers to the colour of the source emission.Different temperature foci are used depending on the type of work.LEDs are available in cold white (6000K), warm white (3000-3500K), natural white (4000-4500K) and other colours (blue, red, green and yellow).
Can LED spotlights replace halogen spotlights?
A 50W, 12V halogen spotlight uses 90% of its energy to generate heat and just 10% to generate light, making it extremely inefficient.These spotlights use a transformer to reduce the voltage from 220V to 12V, consuming between 6W and 12W more.
An LED spotlight, as a replacement for these halogen lights, consumes 90% less energy and lasts 18 times longer.An approximately 7W LED spotlight can replace a 50W halogen dichroic bulb while producing the same level of light.
What is the power factor?
The power factor is a measurement used to describe the quantity of current that contributes to the real power of a load.A power factor of 1 indicates that 100% of the current contributes to the load power; on the other hand, a power factor of 0 indicates that 0% of the current contributes to the load power.
Why is an LED light source more expensive?
LED technology is constantly being developed and has a reasonably complex manufacturing process.However, prices have been coming down over the last few years as this technology makes progress at a fast pace.What's more, it's an investment that you get back remarkably quickly.
What are the main advantages of LED?
The most important advantages of this type of light source are:
- low consumption
- long lasting
- small size
- instant light
- an excellent colour rendering index (reproduction of a light source's colours) of around 90%.
