Versatile & efficient
ORION Lighting offers a wide range of efficient LED lamps with different sockets, light colors and light intensity for every application.
What you need to know
Suspended luminaires, table lamps and spotlights are fitted with a wide variety of sockets and require light sources with matching bases.
With so many options, it is not easy to keep track of everything. That is why we present the most common lamps here in a compact overview.
This makes choosing the right light source child's play for you.
An overview of the most common illuminants
Base and socket
What is a lamp socket?
The lamp socket is the light component that affixes the illuminant in the lamp.
What is a lamp base?
The lamp base is the part of the lamp that makes mechanical and electrical contact with the light. A distinction is made between screw bases, pin bases, plug-in bases and more.
The base must always match the lampholder.
Combine the luminaire of your choice with illuminants from ORION. The high-quality lamp bulbs have a 2-year guarantee.
Lamp bulbs with E base
The Edison screw that is commonly used in Europe, is a right-handed screw thread also known as the incandescent light screw. The most common base shapes include the E14 and E27 bases, that have also been adapted for LED and compact fluorescent bulbs for so conventional sockets can be operated with energy-efficient technologies.
- E10 for bicycles or torches
- E14 for chandeliers as candle or wind gust candle bulbs
- E27 most common lampholder for standard and halogen light bulbs, compact fluorescent and LED bulbs
- E40 with more than 200 W for street lamps
Lamp bulbs with G and S bases
The letter "G " stands for plug-in base illuminants where power is supplied via one, two or more pins.
- G9 for small high-voltage lamps halogen bulbs for chandeliers or ceiling lights
- GU10 for high-voltage reflector bulbs with twist lock for spotlights and spots
- GU5.3/MR16 reflector lamps with plug-in base for ceiling spotlights and spots
- G4 & GU4 halogen lamps with and without reflector
- G13 tube base for neon tubes
The letter "S " stands for sleeve base. They are used for line lamps in tube form.
- S14s for line lamps with two bases
- S14d for line lamps with one base
Lamp bulbs R-base and B-base
The "B " stands for bayonet base, the number behind it stands for the base's diameter in millimetres. For affixing, the bulb is pushed in and then locked in position by turning. These are mainly used in machines or domestic appliances.
- B15d and B22d for appliance lighting, sewing machines and signal lamps.
B15d and B22d lamps are operated directly from the mains voltage. Switiching from conventional to energy- efficient LED bulbs is therefore problem-free; no transformer is required.
Double-ended rod lamps with an R7s base are widely used both outdoors and in homes. They are available in standard lengths of 78 mm, 118 mm and 189 mm with corresponding power levels depending. They exist not only as halogen rods but also as LED rods, that score points for their low heat generation.
- R7s for rod lamps in ceiling floodlights, reading or entrance lamps or for car park lighting
Information about the luminosity of conventional bulbs is supplied by the wattage number. The higher the wattage, the more powerful. When fitting illuminants, the maximum wattage of the socket in any floor, table or pendant lamp must not be exceeded, as there is a fire risk.
For LED technology, we no longer speak of wattage but of lumens when it comes to brightness. With LED lamps, wattage stands for their energy consumption while the lumen number signifies light output.
With a simple formula you can estimate how bright an LED light shines:
Conventional wattage x 10 = lumen value
Lumen value / 10 = conventional wattage
Example: Light with 2,000 lumens / 10 = comparable to 200 watts conventional technology.
So if a light has 2,000 lumens, it shines very brightly.
Light colour temperature is measured in units of Kelvin (1,000 - 8,000 K) and light colour is given in increments of 1,000. We distinguish between three light colours: cool white (daylight white), neutral white and warm white. The lower the numerical value, the warmer the light. The higher the numerical value, the colder and more blue-tinted the light.
A wax candle has a light colour of 1,500 Kelvin. A conventional incandescent bulb has a light colour of 2,700 - 3,000 Kelvin. Daylight, on the other hand, is cold light with a light colour of 5,500 - 7,000 Kelvin.
In our homes, we usually prefer warm, cosy light. In studies or at work stations, in contrast, we need plenty of light and luminosity for demanding visual tasks. If you would like advice on choosing the best illuminant for your dream luminaire, please contact our customer service.
