Light bulbs – Lighting

ENERGY-EFFICIENT LIGHT BULBS

Energy-efficient light bulbs such as LED (light emitting diodes), CFL (compact fluorescent lights), … have replaced the traditional bulbs because these light bulbs use less energy and release very little heat or no heat build-up therefore protecting your lampshade and reducing the risk of burns and fire.
In the near future, LED light bulbs should also replace compact fluorescent light bulbs.

LUMENS

In choosing a light bulb, you must know the needs in LUMENS (unit of measure of the total quantity of visible light emitted by a source) and not in WATTS (unit of measure of electrical power consumption). Lumens indicate the lighting produced by a light bulb.

Light bulb packaging today helps us by giving the equivalent power of incandescent light bulbs, but we should get into the habit of looking only for lumens (lm) and not watts (w).

* As of January 1st 2013, incandescent light bulbs are no longer available on the European market.
** Since September 1st 2018, halogen light bulbs are no longer released on European markets and are gradually disappearing.

INCANDESCENT LIGHT BULBS

Many countries today no longer produce or import incandescent light bulbs (traditional light bulb). These light bulbs are no longer available on the European market and should disappear completely.
If you still have incandescent light bulbs in your home and in your country, here are a few rules to respect :

  • A minimum distance is required between the bulb and the lampshade :
Light bulb distance required between an incandescent light bulb and a coolie shaped lamp shade.
Light bulb distance required between an incandescent light bulb and a drum shaped lamp shade.
Light bulb distance required between an incandescent light bulb and a cylinder shaped lamp shade.

Minimum distances required between an incandescent light bulb with different wattage and the interior of a lamp shade.

  • Verify that the wattage of your light bulb is adapted to the width size of your lampshade. A light bulb too strong (too hot) could alter, even burn, your lampshade if the lampshade size is insufficient.
  • You can also verify the lamp base recommendations for wattage, but it is especially the lampshade that determines the maximum wattage allowed.
  • Again, think of using low energy-efficient light bulbs to protect your lampshade, reduce energy consumption and heat production.

NATHALIE HANNON’S LAMPSHADES

For Nathalie Hannon’s lampshades, the maximum wattage recommended only concerns incandescent light bulbs, because these bulbs heat up. We strongly discourage the use of halogen light bulbs.
