It deals with key aspects of the Christian life and speaks more to the heart than to the head. A light engineering term exists for the measurement of the rate at which a lamp is able to convert electrical power (Watts) to Light (Lumens) - this is referred to as luminous efficacy (or just efficacy) - and is expressed in Lumens per watt (LPW) or Lumens per circuit Watt.
