G9 light bulbs: The former halogen star with an LED future
:format(jpeg) "G9 3W 830 LED pin lamp dimmable")
G9 light sources have become an integral part of lighting. This is less due to the not so unusual pin base. Rather, it is due to the illustrious history of the G9 light source, which originally used exclusively halogen lighting technology.
Halogen light offered one hundred percent color rendering and excellent brightness. The G9 lamp condensed this into a light source with the smallest dimensions, meaning that the G9 lamp was used wherever small light sources had to be inserted into luminaires. Today, they are used in ceiling lights and pendant lights in private homes as well as in doctors' surgeries, showrooms and offices.
What does G9 mean for lamps?
G9 refers to a high-voltage lamp without reflector The light is emitted virtually all around and is non-directional (but can of course be directed by the shape of the lampshade). Today, G9 no longer automatically stands for a halogen lamp, but only for the base with a distance of 9 mm between the pins (hence the nine in the designation) and the condition that no reflector is installed. The lighting technology, however, differs from G9 to G9 lamp.
Is G9 also available with LED instead of halogen?
Originally, the G9 base was reserved exclusively for halogen-based high-voltage lamps. Today, other lighting technologies are also used with the G9 base, namely energy-saving lamps and LEDs. Halogen lamps are no longer the light source of choice. LED lamps in particular are outstripping all other light source technologies (including energy-saving lamps).
G9 LED lamps ...
- are more environmentally friendly! They save around 60 % energy compared to the halogen version.
- are almost maintenance-free! Their service life is up to 50,000 hours or (at 4 hours of operation per day) more than 30 years.
- offer 100% brightness immediately, which is a clear advantage over energy-saving lamps.
- **The higher purchase costs pay off due to the energy efficiency and service life.
- Different light colors are possible: warm white for living rooms, universal white for kitchens and offices and daylight white for utility rooms.
- **When buying, make sure you buy high-quality branded products such as those from Osram or Lampenwelt.com. However, flickering is perceived very differently from person to person and some people are particularly sensitive to it.

How bright does a G9 LED need to be?
G9 lamps are rarely responsible for illuminating the room as a single unit. In most cases, e.g. with multi-flame ceiling spotlights, several of these are responsible for the room lighting. G9 lamps are then used, each with a luminous flux of 200-400 lumens. Both halogen and LED cover this brightness well. Information on brightness can be found in the article details in our store under the line "Total lamp luminous flux".
Tip: However, LEDs achieve the same brightness as halogen lamps with significantly fewer watts. For example, a 4-watt LED light source can generate as much brightness as a 33-watt halogen lamp. The switch is worth it!

How do I convert G9 halogen lamps to LED?
You don't need to take anything special into account when switching to G9 LED lamps. You should only keep an eye on the light color\ differences mentioned above when making your selection. The LED light source is then inserted (and removed) in exactly the same way as the conventional halogen light source. The G9 base is identical for both types of light source. Only the lighting technology differs.
Lamps that are so easily backwards-compatible are also known as retrofits - and they are available for almost every common socket You don't need a transformer for high-voltage lamps, as they work with the usual voltage of 230 volts. You can also opt for dimmable light sources. However, these must be specially labeled as dimmable.
