|LONDON Nike Air Max 90 Clearance Canada , Nov. 21 (Xinhua) -- Basel will become the first city to jointly host the Badminton and Para Badminton World Championships after it was awarded the 2019 edition of the Para event.
The Badminton World Federation (BWF) confirmed on Tuesday that the two tournaments will be staged simultaneously for the first time.
The Swiss city defeated Tokyo to land the 2019 Para Badminton World Championships in a vote which was delayed by the BWF Council to allow "further discussion."
The event will be the last held in the sport before Para Badminton makes its Paralympic Games debut at Tokyo 2020.
There will be 14 medal events in badminton at the 2020 Paralympic Games.
In the old days there was only 1 type of light bulb, incandescentand the only chose you had was what wattage. Now there are lots of different lighting technologies to choose from. I want to discuss the reasons for choosing one bulb over the next. Lighting design can make or break a design so selecting the right light is critical. If you are a restaurant designer you want to make the food look good. If you are a retail designer you want to make the merchandise look good. You get the point. There are 4 properties that I want to focus on to give a good foundation in what to look for when selecting a light.
Wattage. The is often misused when discussing lights even though it is the most common and apparently straight forward property of a light bulb Wattage is simply a measurement of the amount of electricity used by a bulb Nike Air Max 90 Shoes Canada , but it is often used as a proxy for the amount of light a bulb produces. This worked out fine back when all lights were incandescent, but now that we have new technology we need to be accurate about what wattage means. Electricity is purchased by kilowatt-hours (1000 watts per hour written ‘Kwh’) so you can simple take the bulb wattage times electric rate (Say 10 cents a Kwh) and get how much you would pay to run that bulb for 1000 hours. It costs $10 to tun a 100 wall bulb for 1000 hours at $0.10 per kwh. (60x$0.1=$6)
Lumens. The real measurement of light output is Lumens not Wattage and it is abbreviated ‘lm’. In case you were wondering the technical definition is ‘a unit of luminous flux Nike Air Max 90 Essential Canada , equal to the luminous flux emitted in an unit solid angle by a point source of one candle intensity.’ So what that means is a candle is 1 lumen. If you want to understand the efficiency of any given light divide the lumens by the wattage to get lumens per watt. A traditional 60 watt incandescent light produces about 500 lumens or 8.3 lumens per watt. The newer 20 watt CFL kicks out a nice 960 lumens or 48 lumens per watt, take that.
Color Temperature. This gets a little more complicated Nike Air Max 90 Ultra Essential Canada , but in design terms it is probably the most important. Color temperature is the measurement of the lights color stated in units of absolute temperature, kelvin (K). The color of the light has a great impact on the look and mood of a space. Yellow incandescent bulbs have lower color temperatures Nike Air Max 90 Ultra Flyknit Canada , but are oddly referrer to as warm light. Old cool white fluorescent lights the look blue or green have higher color temperatures Science and design in conflict again Traditional incandescent lights are around 2,700K and are visibility yellow and the first generation fluorescent lights were 4 Nike Air Max 90 Ultra Canada ,000K and blue-green in color.
(CRI) Color Rendering Index. In design this is nearly as important as Color Temperature. If you were wondering this means the ‘Effect of an illuminant on the color appearance of objects by conscious or subconscious comparison with their color appearance under a reference illuminant’. What this means is how well can you make out the color of something with any given light. Despite the definition the scale is nice and simple 100 is perfect and 0 is terrible. In practice anything over 80 is fine and most any modern fluorescent, halogen or high end ceramic metal halide light will meet this requirement. If you are lighting up artwork 90 is a good starting place. Regular (read cheap) Metal Halide lights can be down in the 50 to 70 range which is fine in a warehouse but not a restaurant or retail application. I could mention quiet a few stores that do use Metal Halide lights and suffer for it.
I hope this helps to reduce the confusion about light selection.

It’s renowned that because cold season gets closer, wild rodents walk into properties with less difficulty and at the same time increase their appearance in some people’s home gardens.

Rats and residence mice leave unclean black smears along well walked passages in particular where they ought to squeeze underneath items.
