Replace & Install Compact Fluorescent Bulbs
Replace your regular light bulbs with compact fluorescent bulbs. They use just a fourth of the energy. Most take up a little more space than regular bulbs, but they will still fit in lots of light fixtures.
Flourescent bulbs used to be criticized for the flickering, bluish light they gave off . But now we can get flourescent bulbs that almost match incandescent bulbs for warm light and color.
For really small fixtures, you will want sub-compact flourescent lamps, which can be easy to find in the site.
Now you can even get compact flourescent bulbs that will work in 3-way fixtures.
Word of caution: never put a compact flourescent bulb in a circuit with a dimmer unless the bulb is specifically designed to be dimmable.

Compliance with safety regulations and other standards
Luminaires should not only look good and provide good light, they must also be safe. Safety is guaranteed by compliance with a variety of regulations and standards. Luminaires should meet all relevant national and international regulations.

Protection against electrical shock
Each luminaire is insulated so that any exposed metal parts do not carry electrical current. Parts that carry current during normal operation must be protected against contact either by insulation or a suitable cover. Additional measures are taken to prevent exposed metal parts carrying current even if an insulation fault occurs. The table on the right contains the three protection classes used in Germany.
Unless otherwise indicated on the rating plate, luminaires comply with protection class I.

Notes |
| I |
 |
Luminaires with a terminal for a protective conductor to which all metal parts that could carry current in the event of a fault must be connected. |
Connection to a protective earth conductor absolutely essential. The symbol is displayed on the terminal. |
| II |
 |
In luminaires with this symbol there must be no exposed metal parts that could carry current in the event of a fault (total insulation or double insulation). |
The luminaire does not have to have a protective conductor terminal and does not have to be connected to a protective earth conductor. |
| III |
 |
Luminaires to be operated with safety extra-low voltage (SELV), i.e. voltages under 50 V generated with a safety transformer to VDE 0551 or supplied by batteries (standard or rechargeable). |

Protection against dust, solid materials and water
Luminaires must belong to a particular protection class against moisture and dust to which they are exposed. The lowest protection class is "covered"; in other words, the luminaires have no protection against moisture or dust but are covered in such a way that it is impossible to touch electric parts without using a tool.
Luminaires without any indication of a protection class are classified IP 20. The following table gives an overwiew of the protection classes, their definitions and their symbols:

Protection against ignition/fire
When operated, luminaires generate heat. The following symbols are used for luminaires that can be mounted on flammable materials:
| PROTECTION CLASSES WITH REGARD TO IGNITION/FIRE |
| Symbol |
Description |
 |
Luminaires are suitable for direct mounting on normally flammable materials, in which you may not exceed 130° C (in normal operation) and 180° C (in fault case) for less than 15 min. |
 |
Luminaires are suitable for direct mounting on materials that have normal or reduced flammability, in which you may not exceed 95°C (in normal operation), 130°C (in annormal operation) and 180°C (in fault case) for less than 15 min.
Maximum temperature on the mounting surface: 130 °C. |
 |
Luminaires are suitable for direct mounting on materials for which the flammability properties are not known, in which you may not exceed 95°C (in normal operation) and 115°C (in abnormal operation + fault case). |

Installation regulations for luminaires in domestic bathrooms to VDE 0100, Part 701
As far as protection against water is concerned, the luminaires must comply with the types of protection indicated here. Shock-hazard protection and protection against solid parts have to be least IP 2X.
Zone 0
Luminaires with IP X7 (e.g. IP 67) and rated voltage up to 12 V. The luminaires must be suitable for wet rooms.
Zone 1
Luminaires with IP X4, (e.g. IP 44) and rated voltage up to 25 V. IP X5 (e.g. IP 45) is required in showers with high water pressure (e.g. ones with massage shower heads).
Zone 2
In Germany, luminaires must comply with IP X0 (e.g. IP 20),all other European countries require IP X1 (e.g. IP 21). All other electrical equipment in this zone must comply with IP X1. |

Installation instructions
CE labelling
With the CE labelling the conformity of a product is certified with the prevailing EC guidelines, like the the low-voltage guideline 73/23/EWG or the EMV guideline 89/336/EWG.
The marks licence forms the basis for the declaration of conformity by the manufacturer.
Of course, all our luminaires meet the requirements of the relevant EC guidelines and therefore carry the CE label.
Proved security

The meaning of the VDE-mark |
Products with VDE approval mark are:
- electrically safe
- mechanically safe
- thermally safe
- standard compliant
- supervised by VDE during production
VDE (Association of German Electrotechnical Engineers) is carrier of the independant German test and certification institute. The VDE approval mark may only be used if a product has been approved after intensive tests according to actual international and/or German standards.
Approval marks comparable to VDE of other certification authorities are for example DEMKO in Denmark, FI for FIMKO in Finland, IMQ in Italy, N for NEMKO in Norway, S for SEMKO in Sweden and SEV in Switzerland.
All of them are independent approbation organisations.
These organisations test the safety of luminaires according to the European luminaire standard EN 60 598 under consideration of national deviations. In addition, they are also responsible for testing the electromagnetic compatibility of luminaires according to European standards.

 |
The meaning of the ENEC-mark |
Similar to VDE, ENEC is a common European safety mark, which is recognized by all European approbation authorieties.
ENEC stands for European Norms Electrical Certification. The number following the sign indicates the country of certification, i.e. 10 = VDE or 13 = SEV.
 |
The meaning of the CE-mark |
The CE-mark is a certificate for authorities, for example when products crossing the border.
With the CE certificate a manufacturer declares the conformity of his products with European guidelines without tests from an independent organisation.
Two guidelines apply to luminaires:
The low voltage guideline and the EMV guideline for electromagnetic compatibility.
This guideline contains only general requirements, no details like the European standards.
