6,500 kelvin — and why not less
All LED magnifying lamps in our range work at around 6,500 kelvin. That is a deliberate choice, not an accident — and it explains why the light feels different from the lamp in your living room.
What kelvin describes
Colour temperature says whether light appears warm or cool. The scale runs against intuition: the higher the value, the cooler the light.
| Kelvin | Name | typical for |
|---|---|---|
| 2,700 K | Warm white | living rooms, classic incandescent bulb |
| 4,000 K | Neutral white | offices, retail spaces |
| 6,500 K | Daylight white | workplaces, inspection, colour judgement |
The reference point is an overcast sky at midday — that is roughly where 6,500 kelvin lies. Hence the name daylight white.
Why a magnifying lamp shines cool
Three reasons, all practical:
- Contrast. Cool light makes fine structures stand out more clearly. A hairline crack, a cold solder joint or a fibre in fabric is easier to see at 6,500 K than at 2,700 K.
- Colour judgement. Warm light shifts everything towards yellow. Anyone determining tooth shades, matching skin tones or checking a paint colour needs a neutral basis — otherwise the judgement no longer holds in daylight.
- Alertness. Cool light has an activating effect. In concentrated detail work that is an advantage you notice by the fourth hour.
The downside — and what helps
Daylight white has a higher blue component. In the evening that can affect sleep, and some people find it harsh. Two things help:
- Match the ambient light. A cool magnifying lamp in a warmly lit room creates a strong contrast jump. A neutral-white surrounding is more comfortable than a warm one.
- Dim it down. Less light at the same colour temperature is considerably more tolerable in the evening. More on this in the article on dimmability.
For users who find the blue component too high in principle, we stock a glare-free desk lamp with a low blue component — although without a magnifier.
Kelvin is not colour rendering
The most common misconception to close with: colour temperature says nothing about how true colours look. It only describes the basic tone of the light. Whether red really appears red depends on the Ra value — two lamps with identical 6,500 K can be far apart there. What the Ra value means is set out in the article on CRI.
