#TheDress or how differences in lighting affect people's perception of colour

Choosing the right lighting for a retail shop is fundamental. Whether it's accent, ambient or general lighting, the lamps and luminaires you choose can change the way customers perceive the colour of a room, the shade of an item in a shop window, on shelves and in displays.

In the worst case scenario, for example, the colours of a striped dress could be perceived as white with gold instead of blue with black...

You don't believe it? Just such a phenomenon triggered an internet hype in 2015, which caused a furore with the hashtag #TheDress. Continue reading

Wiedergabe von Weißtönen ohne ultraviolette Strahlung

In verschiedenen Beiträgen hier im danholt Licht-BLOG habe ich die Bedeutung der verschiedenen TM-30-Kennzahlen erläutert und erklärt und wie Lichtdesigner und Anwender sich von ihnen leiten lassen können.

Der TM-30 ist jedoch auch für andere Akteure in der Beleuchtungswelt nützlich, einschließlich der Hersteller selbst. Bei der Entwicklung einer Lichtquelle geht es oft um Kompromisse - zum Beispiel können wir entscheiden, ob wir die Lumen (Lumen/Watt) oder die Farbwiedergabe in den Vordergrund stellen.

Colour enhancement based on TM30

When should we use such colour-enhancing light sources? This is an interesting question to which there is no simple answer.

First of all, we need to realise that just because something is preferred in a comparative experiment does not always make it better. Let me give an analogy here: If you serve two otherwise identical dishes, one of which contains more salt than the other, most people will favour the saltier dish. However, we certainly don't conclude from this that more salt in our food is always better! Continue reading

TM-30 and colour enhancing products | SORAA Color Enhance

There are a variety of colour enhancing LED sources on the market, but as far as I can fairly judge the competitors' products, I have to say that I'm not impressed with what I've seen so far. In short, these products often have an unpleasant way of saturating colours while producing a pinkish hue of light. We are familiar with these lights from meat and sausage counters in various supermarket chains, for example.

No more pink-red islands of light, but consistent colouring with the same white point and yet the desired colour enhancement of the red tones for the counter display would be desirable. This is exactly what you can achieve with the SORAA Enhance Filter in combination with the SORAA Vivid LED.

The CRI value (Color Rendering Index) is supposed to determine the color fidelity of light sources - but it (usually) doesn't!

How do you explain color, and more specifically, how do you explain right color as opposed to wrong color, because that's important when it comes to understanding light and its idiosyncrasies.

The use of artificial light sources such as e.g. LED emitted light has various aspects and characteristics that need to be taken into account.
CRI values have become the most common way to assess color fidelity. But there's more to understand and consider when it comes to colour rendering and light quality – in this respect, the CRI value of a light source is not very meaningful.

TM-30 the new measure of color - the better Color Rendering Index (CRI)

The new standard of color rendering index

Together with scientists from SORAA Inc. and the Illumination Engineering Society (IES), a new and improved method for measuring the color rendering quality of illuminants was developed, which far exceeds the accuracy of the CRI value previously used.

Museums, galleries, upscale hotels and restaurants have been relying on high-quality light and SORAA full-spectrum LEDs for some time now.

In the meantime, retailers are also discovering the tangible advantages of full-spectrum LEDs for their stores. In addition to significant energy savings and exceptional light quality, the full-spectrum light improves the presentation of the goods and attracts buying customers.

The newly opened socks and stockings shop of eiei 4 Retail GmbH in Heidelberg , for example, puts its colourful socks and stockings in the limelight really well!

Thanks to the excellent light quality of the SORAA full-spectrum LED, the colours of the textiles are presented in a fresh, intense and lifelike way.

That's exactly what attracts buying customers.

In addition, the Soraa Snap system offers unbeatable flexibility for precisely these light sources when it comes to the exact, accentuated and pinpoint illumination of goods. Not only can the respective beam angle of the LEDs be adjusted at any time, but also the light cone geometry, light colour and saturation as well as glare protection. Rectangular, square and elliptical light cones can also be realised in seconds with a "snap".
New season, new merchandise... no problem, always perfectly customised light in no time at all.

This is what the management says:

"I am absolutely satisfied with the light quality of the SORAA full-spectrum LEDs, and the filters allow the individual product areas to be wonderfully illuminated. I would like to equip our next store with the Soraa lamps again."

We are very pleased that we were able to make a small contribution to the success of this colorful shop with our SORAA full-spectrum LEDs and wish them much success, enthusiastic customers and good sales!

The SORAA LED Snap System explains...

Combine one or even several snap bezels with a snap-compatible* SORAA LED**. A snap bezel is simply attached magnetically in front of the lens of the LED. Change the light cone geometry or the light colour in the blink of an eye, increase the colour contrast or ensure freedom from glare and much more.

Maximum energy savings with brilliant light quality!

The SORAA brilliant HL LEDs offer excellent colour rendering and colour contrast with maximum luminous efficacy per watt.

HighLights of the SORAA brilliant HL LED:

• High light output
• Dimmable
• Point Source Optic - focused light cones
• Brilliant, bright light
• Excellent colour rendering

Artificial light with the quality of sunlight is changing the world
