The three-digit code on the lamp packaging usually contains information regarding the quality of light (color rendering index and color temperature).

First digit color rendering index in 1x10 Ra (compact fluorescent lamps have 60-98 Ra, so the higher the index, the more reliable the color rendering)

Second and third digits indicate the color temperature of the lamp.

Thus, the marking "827" indicates a color rendering index of 80 Ra, and a color temperature of 2700 K (which corresponds to the color temperature of an incandescent lamp)

Table 1. International marking

Code	Definition	Features	Application
530	Basic warmweiss / warm white	Warm tone light with poor light transmission. Objects appear brownish and have little contrast. Mediocre light output	Garages, kitchens. It has become less and less common lately.
640 740	Basic neutral weiss / cool white	"Cool" light with mediocre color rendering and light output	Very common, should be replaced by 840
765	Basic Tageslicht/daylight	Bluish "daylight" light with mediocre color rendering and light output	It is found in office premises and for highlighting advertising structures of citylights
827	Lumilux Interna	Similar to incandescent light with good color rendering and light output	Accomodation
830	Lumilux warmweiss / warm white	Similar to the light of a halogen lamp with good color rendering and light output	Similar to 827, with a slightly bluish tinge
840	Lumilux neutralweiss / cool white	White light for work surfaces with very good color rendering and light output	Public places, offices. External lighting
865	Lumilux Tagslicht / daylight	"Daylight" light with good color rendering and mediocre light output	Public places, offices. External lighting
880	Lumilux sky white	"Daylight" light with good color reproduction
930	Lumilux Deluxe warmweiss / warm white	"Warm" light with excellent color reproduction and poor light output	Accomodation
940	Lumilux Deluxe neutral white / cool white	"Cold" light with excellent color rendering and mediocre light output.	Museums, exhibition halls
954 965	Lumilux Deluxe Tageslicht / daylight	"Daylight" light with a continuous color spectrum and mediocre light output	Exhibition halls, aquarium lighting

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Muse Technologies for Thought Control 17.08.2013

InteraXon, a start-up company working on a thought-computer control interface, has raised its first major investment of $6 million by giving investors a stake in preferred stock.

Chief Executive Ariel Garten announced the deal yesterday at the GROW startup conference in Vancouver. She also demonstrated the company's product - a comfortable and neat six-sensor Muse headband that replaces the traditional encephalogram device.

"Muse is a rim that is sensitive to the biocurrents of the brain, allowing you to track its cognitive and emotional activity. It increases your attention and helps you better understand the emotions you are experiencing," Ms. Garten said.

InteraXon started with a successful Indiegogo campaign that raised $287 to launch the first series of devices. The public attention the project has generated has been an important investment case for Horizons Ventures, OMERS Ventures, ff Venture Capital, Felicis Ventures, Bridge Builders Collaborative, and A-Grade Investments, an investment company founded this year by actor Ashton Kutcher. ), who played the role of Steve Jobs.

The funds raised will be used to improve algorithms and release more devices on the market. The Muse device allows you to control the computer and games, reduce stress, improve memory and concentration, - the company says - ultimately this computer-brain interface will allow you to mentally control the surrounding devices.

The company says that Muse with bundled iOS and Android mental exercise software and SDK will begin shipping in late 2013. The cost of the device is not very high and even now it is $200.

It is hoped that InteraXon technology will appear in future devices such as Google Glass digital glasses and Oculus Rift virtual reality glasses, and will expand the scope of wearable computing with a simple and always accessible control tool.
