Ampoules LED Lighting

Long-Term Electricity Savings

The most successful and most economical bulbs are now the LED, but we do not buy them as they bought a conventional incandescent bulb or even today, a halogen.All our tips to make the right choice in store.

Ampoules LED Lighting

With incandescent bulbs and halogens, speaking in watts (W), since their brightness depends on their power consumption. This is not the case with LEDs. For proof, high-performance LED lights 6W as well as an incandescent bulb 60 W or halogen 46 W. Central information LED, it is the lumen (lm).

Lumens

Their number expresses the amount of dimmable LED light produced by incandescent bulb. The more lumens, the more light.

How long does it lumens to replace an incandescent bulb?

  • 1521 lm for a 100 W bulb
  • 1055 lm for a 75 W
  • 806 lm for a 60 W
  • 470 lm for a 40 W
  • 249 lm for a 25 W

Watts

Conversely lumens, watts have more interest with LEDs: they have nothing to do with the intensity of the light produced. They only indicate the consumption of electricity, which is always minimal. A LED bulb consumes in fact 10 times less electricity than incandescent 6-8 times less than a halogen.

Choose classic led or led “retrofit” filament?

The “retrofit” consume much less than LED “classic”, but 4 W / h instead of 6 W / h for the same light output, this has no impact on the electricity bill as consumption is low: year, the gap is only 30 cents for an average burning time of 1000 hours.

The Color Temperature

After lumens, this is the second important information, LEDs can produce a warm light similar to that of incandescent or a cool white.

We speak of warm light between 2700 and 3200 Kelvin, cold light beyond 4000 Kelvin.

The color temperature may be indicated by:

  • The number of Kelvin (K)
  • Color (yellow for hot, blue for cold)
  • The words “warm”, “warm white” or “warm light” for hot, “cool white” For the cold.

The Drive Logo

The LEDs are all dimmable. When they are not, the logo is barred.

Lifetime

10 000, 15 000, 20 000, 25 000 hours … or 10, 15, 20 or 25 years announced lighting: LED manufacturers play upmanship. No need to attach importance to exceptional longevity displayed on packaging, life spans are calculated by extrapolation from tests on electronic components and not on the bulb itself.

Besides, the 16 LEDs that our test account , many have dropped or lost a lot of light before the deadline of 3000 hours of testing, and our results show that buying a great brand does not in immune to surprises.

Warranty

3 years, 5 years warranty or not, must be vigilant that it changes something. Keeping your receipt as proof of purchase is necessary, return the defective LED too. Osram provides on request a T label for the return of the bulb free of charge during the warranty period.

Profitable, leds?

Despite an average price of € 10 instead of € 3 or less for a halogen, LED cost ultimately much cheaper than halogen. “Que Choisir” has accounts for an equivalent bulb to a 60 W incandescent, the results are revealing:

(LED bought € 10, halogen € 2.60 piece kilowatt hour is 15 cents, and the bulb lights up 1000 hours per year, or 3 hours per day.)

  • For 3 years lighting

LED: 14 €
Halogen: 26 €

  • 5-year lighting

LED: 16 €
Halogen: 42 €

  • For 10 years lighting

LED: 22 €
Halogen: € 82

LED is much more efficient than halogen because it consumes 6 times less and it still operates at 10 000 hours, while it took to buy at least 5 halogen – and it will probably take longer actually because they rarely take 2 000 hours announced.

Risks to the view?

LEDs have beautiful suit all uses and have become competitive, do not buy anything. Some pose risks to the view. In the current state of the market, “Que Choisir” advises spots and clear glass bulbs with exposed diodes. The National Health Security Agency (ANSES) has warned consumers in 2010 , pointing to health risks their high proportion of blue light. For white LEDs, are added in fact a yellow phosphor powder layer to the blue LED. This phototoxic blue light is to the eye, causing a harmful stress to the retina. The risk is particularly high for children. Their crystalline in development, it can not effectively filter blue light. ANSES also highlighted the risk of glare and visual discomfort. Since then, research is ongoing and the study of Inserm published in 2015 confirms the risks .

Note
When the LED diodes have neither apparent nor directional beam of light, they present no risk to eyes. On models “retrofit” (transparent glass filaments), the phosphor layer is protective.
