Green Duralamp
Why should I replace less efficient lamps with energy saving lamps?

1) Because you will save on your electricity bill
2) Because you will reduce your energy consumption and the harmful emissions needed to produce the same
3) Because you can PERSONALLY contribute to creating a better, cleaner future


 Do you need any more convincing?



New shapes 
Lots of different shapes to suit all appliances and lighting needs.
Very small formats: Duralamp has long been ‘fixated’ with miniaturization, leading it to constantly reduce its lamp sizes

Light effect
Energy saving lamps offer a wide selection of light colors. From the warm, intimate light of the incandescent lamps they are replacing, to a ‘brighter’ or natural light - ideal for kitchens, for example - to the cold light needed for many working environments.

You can choose the light you need.

Starting time
The current energy saving lamps switch on IMMEDIATELY (switching on time < 2 seconds). Even if the human eye can see a satisfactory light after just a few seconds, ‘exposed tube’ lamps take less than 30 seconds to reach 100% of the flux, whereas bulbs with a cover, such as, for example, round lamps and globes, can take up to a maximum of 60”. The longer time required is due to the technical choice to improve efficiency and lengthen the life of these covered bulbs which work at higher temperatures.

Replacement costs
The cost of a good electronic energy saving lamp is undoubtedly higher than that of an incandescent lamp. But it also has a much longer life (between 8 and 14 times longer!): this means that you buy JUST ONE energy saving lamp instead of 8-14 incandescent lamps! And energy consumption is reduced by 80%: with truly tangible savings on your electricity bills.

What about businesses? Commercial venues that use a lot of lamps such as, for example, shops with many halogen lamps, also have to take into account the cost of someone coming to change the lamps: if the electrician only has to come once every 12 years, it costs a lot less!

How to choose the right product when replacing
the incandescent lamps in your home
with energy saving lamps?

Above all, it is important to choose the right wattage, i.e. to consume as little electricity as possible whilst obtaining a light that is the same or very similar to the existing lamp.

Duralamp light bulbs' packaging provide the client with all the information necessary to make the best choice:

1) Equivalence with incandescent lamps: this figure is the result of an algorithm set by European Regulation 244/2009.
Often the result of this calculation indicates a wattage which is not available on the market (e.g. 37 W) and is not, thus, the same as the lamp used in the home.
In this case, it is advisable to use the nearest higher value. For example: if the wattage indicated is 37 W, replace with a 40 W bulb.
2) Savings up tp 80%.

Duralux energy saving lamps offer energy savings up to 80%.  A quick calculation of the savings that can be obtained by replacing a 40 W incandescent lamp with a 7 W Duralux Twist show that:

7 W x 0.125 € *x 3 hours of use per day for 9 years = 8.62 €

40 W x 0.125 € *x 3 hours of use per day for 9 years = 49.28 €


To be added to this calculation, on the one side, is the cost of an energy saving lamp and, on the other, the cost of 9 incandescent lamps which have a life of around 1 year: the higher initial cost would be fully compensated by the lower usage costs.    

3) Lamp sizes: useful for users who have appliances with special requirements.
4) Warm up times: this is another piece of information required by European Regulation 244/2009 which refers to the result of the technical analysis upon reaching 60% of the lamp’s nominal flux. However, the high efficiency of Duralamp light bulbs offers satisfactory lighting just a few seconds after they have been switched on.


5) Rated lifetime: the comparison is once again made with an incandescent lamp. A Duralux Eco, like the one in the box shown here, has a lifetime which is the equivalent of 12 incandescent lamps, normally estimated at 1000 hours. The lifetime indicated is calculated in compliance with the relevant European directives (see the Glossary). (2)

6) Number of ON-OFF cycles: the European Directive requires a statement of the number of times the lamp can be switched on and off before failure. Duralamp has chosen to indicate the real number of cycles and not a theoretical number obtained from statistical estimates.

7) Use of  Mercury: although Duralamp uses the latest technology to limit the use of mercury, a minimum quantity of this metal is essential for the functioning of fluorescent lamps: please refer to our TECHN INFO section for information about the correct way to dispose of these lamps.

(2) Obviously the conditions of use enormously influence the lifetime of a light bulb.  Here are some elements to keep in mind than can strongly affect the lamp’s real lifetime: a higher than normal operating temperature (for example, inside a closed appliance); the operating position (for example, with the tubes pointing downwards causing the heat to rise towards the plastic part containing the circuit); frequent switching on and off (which damages the filament); sudden changes in voltage or, in general, disturbances to the electrical supply.
