What is A Headlamp / Head Torch?
A headlamp (known as a headtorch in the UK) is a light source affixed to the head for outdoor activities at night or in dark conditions such as caving, orienteering, hiking, skiing, backpacking, camping, mountaineering or mountain biking. Headlamps may also be used in adventure races. Headlamps are often used by workers in underground mining, search and rescue, surgeons, and by other workers who need hands-free lighting.
 
Headlamps are usually powered by three or four AA or AAA batteries. Systems with heavy batteries (4xAA or more) are usually designed so that the light emitter is positioned near the front of the head, with the battery compartment at the rear of the head. The headlamp is strapped to the head or helmet with an elasticized strap. It is sometimes possible to completely disconnect a headlamp's battery pack, for storage on a belt or in a pocket.
 
Lighter headlamp systems are strapped to the user's head by a single band; heavier ones utilize an additional band over the top of the user's head.
 
White LEDs were quickly adopted for use in headlamps due to their smaller size, lower power consumption and improved durability compared with incandescent bulbs.[citation needed] Power LEDs rated 1 watt or more have displaced incandescent bulbs in many models of headlamps.[citation needed] To avoid damage to electronic parts, a heatsink is usually required for headlamps that use LEDs that dissipate more than 1W. To regulate power fed to the LEDs, DC-DC converters are often used in 1W+ lights, sometimes controlled by microprocessors. This allows the LED(s) to provide brightness that is not affected by a drop in battery voltage, and allows selectable levels of output. Following the introduction of LEDs for headlamps, sometimes combinations of LED and halogen lamps were used, allowing the user to select between the types for various tasks.
 
Rayfall LED headlamps, with high quality standards, will be your best choice for hands-free working or outdoor sports lighting needs at nights.
