Garden lighting done with LED lights is effective and consumes very little energy compared with the days of incandescent bulbs. You can significantly influence the power, colour temperature and atmosphere of your garden lighting, simply by changing the bulbs in the existing luminaires.
If a light source needs to be changed in luminaires, there is plenty of choice. An LED bulb is a good investment: high-quality LEDs are durable and last for many years in service. The service life is indicated on the pack. It is often difficult to change a bulb in a garden luminaire so, in order to save work, it is worth selecting an LED bulb with a long service life.
How much light?
Previously, the power of a bulb was expressed merely in watts. Nowadays, the amount of light is given on the pack in lumens. Airam has made it easier for consumers to choose by marking on the pack how watts correspond to lumens, both in numerical and colour symbols.
Light colour temperature
Light colour temperature is largely a matter of taste. The higher the Kelvin value, the bluer and colder the light is. Warm light is between 2700 and 3000 K and bright white light, 4000 K. The corresponding Kelvin value for daylight is 6500 K.
- LEDs can generally withstand very cold temperatures but, in Finnish conditions, particularly in northen areas, for garden luminaires it is advisable to select frost-resistant bulbs right from the start, literally during good weather. The range of operating temperature for frost-resistant bulbs is -40 - +40°C.
- Tubular-lamps are suitable for high and narrow luminaires. They emit even light to the whole diffuser. Colour temperature bright white 4000 K.
- Radar-lamps have a built-in motion sensor and twilight switch. When the bulb is switched on it illuminates for four seconds. After that it is triggered by movement when the ambient level of light is less than 50 lux. The lamp remains on for 40 seconds with repeated movement continuing for 40 seconds at a time. Two colour temperatures, 2700 K and 4000 K.
- Sensor twilight-switch lamps are designed to switch on automatically at dusk (below 15 lux) and off at dawn.
- The Day Light LED emits bright light with a colour temperature of 6500 K corresponding to daylight. The daylight lamp spectrum is continuous and particularly highlighted in the blue section.
