Is a LED dimmable?

With the new LED technology, it has become more difficult to dim bulbs as the technology is quite different from incandescent bulbs.

Nordlux offers dimmable LEDs that can be dimmed if the lamp and driver offers that opportunity. It is important to be aware of the type of dimmer installed in the household, as the old dimmers rarely work with LED bulbs. Read more about dimmers here: (link for dimmer guide). Nordlux offers lamps with build in dimmers.

Do LEDs save energy?

When replacing an incandescent bulb with a LED bulb you save between 70 and 80% energy. The LED has much lower power consumption, as the incandescent bulbs created light from heat, which takes a lot of energy.

The LED creates light from electrons switching places by the help of electricity, causing them to release futons, which takes a visual form as light and is a very low energy process.

What color temperatures can I get from a LED?

To create a cozy environment a 2000-2200 kelvin bulb is suggested. This creates a softer and warm light temperature.

The perfect bulb for above the dining table or a floor lamp next to the sofa, 2700 kelvin is suggested. This creates a natural warm light.

For a working environment lighting, a 3000-4000 kelvin bulb is suggested. This gives a white and focused light setting.

What types of bases are available?

Nordlux bulbs are supplied with E14, E27, GU10, G9, G4 and R7S bases.

How long do LED bulbs last?

Nordlux LED bulbs has an average lifetime of 15.000 hours and a switch cycle of 20.000-50.000. Usually, it is not the LED itself that fails first, but the driver converting the current to fit the needs of the lamp.

What is a maintenance factor?

The maintenance factor of a Nordlux LED is most often at 70. This means that when the bulb has reached its estimated lifetime of e.g. 15.000 hours, the light output would have decreased to 70% of the original 100% output of the stated lumens.

How is the warranty of the LED?

Nordlux provides 5 years of warranty on lamps with integrated LED.

Should I look at watts or lumen when I buy a LED?

You should buy bulbs based on lumen. Watts describes how much energy it takes to produce the lumens. It could be an advantage to look at the lumen/watt number.

The higher the number, the more energy efficient the bulb is. All Nordlux bulbs have the watt equivalent stated on the packaging, just in case you are having a hard time readjusting to the new standards of the LED.

What does the CRI (Ra) value describe?

CRI stands for color rendering index and describes how well a light renders color compared to a reference light source.

For lights with 5000 kelvin or above, the reference source is daylight. If the light is the same as the reference source, the CRI would be 100. Most Nordlux bulbs have a CRI, or Ra, of 80.

Integrated LED vs. ordinary socket (exchangeable)?

In recent years, it has become very common to use integrated LED in light fixtures and lamps.

This has resulted in some entirely new opportunities in lamp design and configuration. Having the light source integrated means that, should an LED stop working, you will have to replace the entire fixture. Fortunately, LED quality has become so good that many LED panels can produce light for up to 30,000 hours.

This means that the lamp can be lit for 16 years, if you have it turned on for 5 hours every day. At Nordlux we provide a 5 year warranty on the LED for lamps with integrated LED. If you prefer the classic lamp with an E27 or GU10 socket, there are also many options - even if you want to use LED bulbs. At Nordlux, we have a large selection of different types of LED bulbs that can be used both indoors and outdoors.
