One measrue of physical fitness is a &quot;step test,&quot; in which a subject steps us on a low platform and then back down (one second for each), and continues this process for 3 minutes.aybe because your muscles are still requiring oxygen since they are still swollen from being used. Oxygen is transported to your muscles via your blood from your lungs and that could be the reason why your heart rate stays elevated.
Old headlights gave off 700 lumens of light; new headlights give off 1,000 to 1,200 lumens; high-intensity discharge lights (the term Xenon is really a misnomer, Bibbo said) give off 3,000 lumens.ld headlights gave off 700 lumens of light; new headlights give off 1,000 to 1,200 lumens; high-intensity discharge lights (the term Xenon is really a misnomer, Bibbo said) give off 3,000 lumens.
Now choosing lights: A typical well built LED downlight provide 80-110 Lumens per watt, letâs consider 100 lumens. So we need total of 20W LED light to get 2000 lumens and 150 Lux for our sample bed room. That means number of LED lights = 20w( total light)/5W(single light) = 4. If you consider florescent tube or CFLs, they provide 60 lumens per watt, but in all directions. So you need more than 35W to get sufficient lighting.
