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.

It’s even possible that you’re staying up too late because of your computer. You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better. f.lux makes your computer screen look like the room you’re in, all the time. When the sun sets, it makes your computer look like your indoor lights. In the morning, it makes things look like sunlight again.

Tell f.lux what kind of lighting you have, and where you live. Then forget about it. F.lux will do the rest, automatically.

You can download this software freely. It is available for Mac, Windows and Linux. Here is the homepage…

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!

As far as I’ve understood, plants benefit mostly from certain wavelengths of light. In order to grow nicely, they need more cool or blue light. When they are blooming, they require some red wavelengths, too. Visual color temperature is measured by the degree of Kelvin. That’s what you have to pay attention to when choosing light for Tulasi.

Full-spectrum lights are as close as it artificially gets to a natural mid-day sun during the late summer. Viva-lite bulbs/tubes have 5500 K which resembles normal daylight. They imitate all wavelengths of light to some degree. Because they have a very high color rendering index (CRI), they don’t distort the actual color impression around them. Lights that have low CRI make everything look weird, either yellow or strangely blue.

The standard incandescent or halogen lamps have around 2500-3000 K, which is not useful for plants. They also emanate a lot of heat and waste energy.”

We couldn’t agree more. Visit namahatta.org to read the full article.
