The goal of outdoor lighting design is no longer simply to light up a space, but to do so in a way that aligns with environmental, regulatory, and perceptual considerations. In this context, the introduction of the 2200K color temperature to the STRAL Lighting's range of stainless steel outdoor fixtures offer a new design solution aimed at reducing the impact of artificial lighting.
Color temperature defines the spectral composition of the emitted light:
4000K → high blue component
3000K → standard urban lighting
2700K → warm light
2200K → amber light, with low blue component
By reducing short wavelengths, 2200K lighting has less impact on the nightscape and ecosystems.
Artificial light affects the behavior of night-active wildlife. Light sources with a high blue component attract insects, disrupt biological cycles, and interfere with species’ orientation. Lower color temperatures, such as 2200K, are less attractive, reduce light pollution, and contribute to greater environmental compatibility.
Cold-color LEDs (e.g. 5000K) emit a strong blue component (approximately 440–460 nm), which is perceived by both humans and wildlife. The greater the emitted blue component, the higher the likelihood of causing alterations to circadian rhythms.
The lighting design is guided by a clear principle: using only the necessary amount of light.
This means avoiding over-lighting, controlling the direction of the light, and selecting color temperatures that are consistent with the surrounding environment. In this approach, 2200K lighting is an effective tool for improving perceived quality and reducing the environmental impact of outdoor lighting.
