They relate to raw electric power by a quantity referred to as luminous efficacy, and so are useful for applications like figuring out the best way to ideal realize ample illumination for many tasks in indoor and outside configurations. The illumination calculated by a photocell sensor would not essentially correspond to what's perceived by the human eye, and with out filters which may be pricey, photocells and cost-coupled products (CCD) are likely to reply to some infrared, ultraviolet or both equally.
