A headlamp is designed to be worn on the head, often having separate lamp and battery components. The battery pack may be attached at the back of the head or in a pocket to improve balance. Headlamps leave the user's hands free. A headlamp can be clipped to the brim of a hat, or built to mount on a hard hat , instead of using straps; other types resemble eyeglass frames. Similar to the headlamp, an angle-head flashlight emits light perpendicular to the length of the battery tube; it can be clipped to a headband, belt, or webbing or set on a flat surface. Some types allow the user to adjust the angle of the head. [11] The Fulton MX991/U Flashlight was an angle-head flashlight issued to US military personnel; similar style lights remain popular.

Luminous efficacy of a light source may be defined in two ways. The radiant luminous efficacy (LER) is the ratio of the visible light flux emitted (the luminous flux ) to the total power radiated over all wavelengths. The source luminous efficacy (LES) is the ratio of the visible light flux emitted (the luminous flux ) to the total power input to the source, such as a lamp. [64] Visible light is measured in lumens , a unit which is defined in part by the differing sensitivity of the human eye to different wavelengths of light. Not all wavelengths of visible electromagnetic energy are equally effective at stimulating the human eye; the luminous efficacy of radiant energy (LER) is a measure of how well the distribution of energy matches the perception of the eye. The units of luminous efficacy are "lumens per watt" (lpw). The maximum LER possible is 683 lm/W for monochromatic green light at 555 nanometers wavelength, the peak sensitivity of the human eye.

A wide variety of beam angles and lighting shapes are available by adding lenses to the individual LEDs (30, 38 or 60 degrees, or create an oval or rectangular lighting pattern, for example). An additional charge of $41 will apply. Please contact us for more details.

Also, the individual LEDs are getting more efficient, which means manufacturers can use fewer LEDs in the bulb to deliver the same amount of light and they will need less aluminum as a heat sink, since there will be less heat to manage. All of this translates to lower costs. The LED bulbs that give off the same amount of light as old 75- and 100-watt incandescents cost more, because they require more LEDs and related materials. Their price, too, will come down with the efficiency gains and the economies of scale that come from higher production levels.
