- Avoid direct calque 'дневная лампа' which is unnatural. Use 'лампа дневного света' (the established term) or 'лампа, имитирующая дневной свет'.
- Do not confuse with fluorescent tubes, often called 'лампы дневного света' in Russian, which have a broader, more technical meaning.
Common Mistakes
- Using 'daylight lamp' to refer to any bright lamp (must simulate daylight spectrum).
- Confusing 'daylight lamp' (specific product) with 'daylight' (time of day).
- Incorrect plural: 'daylights lamp' instead of 'daylight lamps'.

FAQ
Frequently Asked Questions
They are closely related. A SAD lamp is a type of daylight lamp specifically designed for light therapy, often with a very high intensity (measured in lux). Not all daylight lamps are bright enough for clinical SAD treatment.
You can, but the very cool, bright light may feel too harsh or clinical for relaxing environments like living rooms or bedrooms, where warmer light is often preferred.
Quality daylight lamps are designed with filters to minimise UV emission, making them safe for typical use. However, therapeutic SAD lamps should be checked for specific safety certifications.
The technology to produce a balanced, full spectrum of light that truly mimics daylight is more complex than producing standard white light, leading to higher manufacturing costs.
