Better Lighting For Your Computer

Monday, June 7th, 2010

Ever notice how people texting at night have that eerie blue glow? Or wake up ready to write down the Next Great Idea, and get blinded by your computer screen?

During the day, computer screens look good—they’re designed to look like the sun. But, at 9PM, 10PM, or 3AM, you probably shouldn’t be looking at the sun. This little software tool called “F.lux” is all you need to change it. It makes the color of your computer’s display adapt to the time of day, warm at night and like sunlight during the day. (more…)

Lights for Tulasi

Monday, April 26th, 2010

From time to time we are checking the internet for what people say about Viva-Lite. That way we can learn a lot how our customers perceive our brand, products and services.

For example see this feedback on namahatta.org and how well Viva-Lite worked for growing Tulsi:

“We planted Tulasi at home last summer. When she was very little we bought her a 26 W Viva-lite full-spectrum bulb. She was doing well with it. She grew very strong stalk and large, green leaves. Recently we felt she needs more light. We arranged two 36 W fluorescent Viva-lite tubes for her. In Scandinavia there is hardly any natural light at this time of the year! (more…)

The Colour Rendering Index (CRI)

Monday, February 15th, 2010

We felt it is high time to write a brief blog article about the so-called “colour rendering index“, or CRI as its abbreviation is called. The CRI is often quoted in “Ra” (general color rendering index).

What does Wikipedia have to say about the CRI: “The color rendering index (CRI) (sometimes called color rendition index), is a quantitative measure of the ability of a light source to reproduce the colors of various objects faithfully in comparison with an ideal or natural light source. Light sources with a high CRI are desirable in color-critical applications such as photography and cinematography. It is defined by the International Commission on Illumination as follows: ‘Color rendering: Effect of an illuminant on the color appearance of objects by conscious or subconscious comparison with their color appearance under a reference illuminant’.”

As this sounds a wee bit complicated, we’ve prepared an article which (hopefully) explains a bit mor simple what the CRI is and does. (more…)

What Light Looks Like

Wednesday, August 5th, 2009

Have you ever wondered what light looks like? Sure, everybody remembers the prisms in school and the colors of the rainbow. But how good an energy saving lamp – often with its dull colors – really is you can check for yourself now.

Dave – one of our kind customers in Australia has sent us the following pictures of an energy saving lamp with the Viva-Lite Spectrum and the Sunlight as a comparison:

Both photos were taken through so-called “Spectral-Glasses” which you can get in many stores and on the internet. Or buy them directly in the Viva-Lite International Online-Store and compare for yourself…
