A handheld spotlight is a high intensity flashlight that is typically designed to produce a far-reaching beam of bright white light. It features an ergonomically designed handle that offers the user a comfortable grip. The handle usually comes in a pistol-grip or lantern-grip design. The addition of such a handle makes it convenient to carry the flashlight around and allows to use a more powerful light head which often tends to be too bulky to hold in the palm of your hand. As semiconductor-based LED lighting becomes the dominant technology in portable lighting applications, the handle-incorporated design offers a unique advantage over the torch design. The constraint to the thermal design due to the size of a flashlight often leads to the utilization of the housing as part of the heat sink for LED thermal management. The housing of a handleless high power LED torch can run hot over an extended period of operation, even when there’s a rubberized sleeving around the grip. The heat transfer makes it uncomfortable to hold the light in the hand. The use of a dedicated handle provides complete thermal isolation, allowing for comfortable, prolonged use of the LED light.
