A flashlight or torch can be an easily portable hand-held electrical light used to illuminate surfaces for industrial or field work. Previously, the most common source of light found in such applications was a small hand-held portable lamp but since the late-2000s, LED lights have replaced incandescent lights as the new light-emitting diode (LED) lights tend to be more energy efficient and can be put into tighter spaces than their incandescent counterparts. Nowadays, it is not uncommon to get industrial and construction sites using handheld torches instead of and or light mounted on vehicles. The reason behind this change in utilization of torches is because they’re easier to use and take with you.
One of the common uses of a hand held flashlight is for working at night in areas where electrical light is unavailable. One way to use a flashlight in such an environment is to have two batteries available: one with a full charge to serve as a spare, and another with a half charge to be utilized during daytime. To use the flashlight at night, you need to place both batteries on separate charger stands.
If there are no electrical wires available at night, this solves the issue and makes it easy to use the flashlight without the additional lighting. With the flashlight firmly mounted on a stand, a reflector could be attached on either side of the flashlight; a reflector will help light the way even though the torch isn’t totally visible. To provide a larger safety feature, a reflector is attached to both sides of the flashlight.
Two types of reflectors are usually available. In the low-angle-head flashlight, a thin-necked glass bulb is placed in the plastic tube that extends from underneath of the flashlight to a collar-like junction point on the opposite end. At the other end of the necked tube, a metal clip attaches the reflector to a bell or pin to which the battery is attached, also to which the tail of the reflector could be attached.
