Light bulb types – The bulb has much lower energy consumption than ordinary incandescent bulbs. The energy efficiency of an A-bulb is 50-60 lm / watt. Whereas in a normal bulb it is only about 10-12 lm / watt. In the old days it was easy to have an overview of the light bulbs. Then there were two types of sockets and different wattage consumption, as well as round or drop-shaped mignon pears. Fluorescent lamps had different lengths and that was basically all.

The old screw sockets still exist; these are those we find in the so-called E series. The two most widely used variants in Europe are E14 and E27. Where the numbers represent the diameter of the “screw” in millimeters, while “E” is for the inventor of light bulb types – Edison. But there are also many other variants both in Norway and in countries that use other voltages on the mains.

The G9 base bulbs are another variant of light bulb types that came with the halogen technology. They are larger than the smallest halogen bulbs, and run at 230 volts. There are two loops that make contact. And the bulb is only stuck directly into or pulled straight out of the shelf. These bulbs can have very high temperatures and light very strongly. Therefore, lamps that use these bulbs are often supplied with dimmer.
