IST MAGAZINE: Joule Heist
When working with red-light therapy, joules are the most important measurement that we use to determine how much light emission creates the desired result. We are not talking about jewels like diamonds, jade and opal; although for anyone down the path of red light, we all know the sessions might be just as valuable! This measurement of energy is typically in milliwatts (mW) delivered per second; one joule is 1,000 milliwatts. The total energy measurement is joule per centimeter squared, (j/cm2.)
