Retrofit Explained: LED Light Sources as Replacements for Incandescent and Halogen Lamps
What Does Retrofit Mean?
Retrofit (from the English: to retrofit = to upgrade an existing system) refers to LED light sources that can replace conventional incandescent or halogen lamps on a like-for-like basis. They fit into the same sockets (base types) and can be used in existing luminaires without the luminaire itself needing to be replaced or modified.
Which Base Types Are Available as Retrofit?
- E27: The large screw base – standard in many table, floor and pendant luminaires
- E14: The small screw base – typical for candle and globe lamps
- GU10: Pin base for mains-voltage reflector lamps – widely used in spots and recessed luminaires
- G9: Pin base for compact light sources – frequently found in design luminaires
- GU4 / GU5.3: Low-voltage pin bases – for halogen low-voltage systems
- R7s: Linear base – for halogen linear lamps in uplighters
What Should You Look Out for with Retrofit?
- Dimmability: Not every LED retrofit light source is dimmable. For dimmable luminaires, the dimmability of the light source must be verified.
- Dimensions: LED retrofits may be slightly larger than the original light source. The dimensions should be checked before purchase.
- Beam Angle: The beam angle of the LED may differ from the original. This can affect the lighting effect within the luminaire.
- Transformer Compatibility: With low-voltage systems (GU4, GU5.3), the existing transformer must be LED-compatible. Conventional transformers often require a minimum load.
Frequently Asked Questions (FAQ)
Can I simply replace my old incandescent lamp with an LED?
In most cases, yes. Ensure the base type matches, choose the desired colour temperature and – if required – check for dimmability.
Do retrofit LEDs really save electricity?
Yes, considerably. A 7-watt LED can replace a 60-watt incandescent lamp – that corresponds to a saving of over 85 %.
In Summary:
Retrofit LEDs make the switch to energy-efficient LED lighting simple and straightforward. Existing luminaires can continue to be used – only the light source is replaced. At Leuchtenland.com you will find a wide selection of LED lamps for every common base type.
