AMP The abbreviation for ampere and amperage. The unit used to measure electric current.
AMPERE-HOUR One ampere of current flowing for one AMPERE-HOUR One ampere of current flowing for one hour.
ANODIZING An electro-chemical coating for aluminum. Hard, durable, and attractive. Anodized parts are highly corrosion resistant.
BI-PIN BULB A bulb with two contact pins that plug into a socket allowing easy replacement.
BEAM CANDLEPOWER Also called Peak Beam Candlepower. Measurement of the brightest spot in a focused beam. An indication of the maximum intensity of the flashlight. The “hot spot" is equal in brightness to the number of “candles" required to produce the same illumination.
CANDELA Also called “candle." The unit of luminous intensity. One candela is equivalent to 12.57 lumens. At one time it was equal to the light from an actual burning “standard candle."
CANDLEPOWER When referring to flashlights, candlepower is usually the same as beam candlepower. CE Flashlights carrying this symbol meet applicable European Community Directives, and can therefore be sold in Europe.
HALOGEN AND XENON BULBS Flashlights using bulbs filled with these gases are recognized by their extreme brilliance and white light. These bulbs are generally more efficient than ordinary bulbs and may last longer.
HIGH TEMPERATURE LENS Typically made of borosilicate glass which has low thermal expansion characteristics. Easy to clean, resists scratching, and has good shock resistance when properly mounted.
INTRINSICALLY SAFE Not capable of igniting a flammable atmosphere under both normal and “fault" conditions.
LITHIUM Disposable batteries using lithium chemistry are gaining in popularity because of their light weight, high energy density, and shelf life of ten years. Lithium Ion rechargeable batteries, as used in the Strion, combine high capacity with small size and light weight.
LUMEN Unit of luminance. As used in reference to flashlights, it refers to the total amount of light radiated by the bare lamp, the LED, or the flashlight. Because this measurement does consider the focusing efficiency of the reflector, it does not indicate how “bright" the focused beam will appear. A flood lamp with a very wide dim appearing pattern can have the same lumen rating as a very tightly focused intensely bright spot lamp assembly. Lumen ratings cannot be converted to beam candlepower.
MACHINED ALUMINUM Flashlight components made from this material are lightweight, durable, and can be held to tight manufacturing tolerances for superior performance in precision assemblies.
NICKEL CADMIUM (abbreviated NiCd) The most common rechargeable battery used in Streamlight products. It is the most rugged rechargeable technology and provides the highest performance/cost ratio. Must be recycled at end of life. NON-INCENDIVE Not capable of igniting a flammable atmosphere under normal operating conditions.
NON-CONDUCTIVE Will not conduct electricity. Flashlights made with non-conductive case materials protect against electric shock should the flashlight touch an electrical source.
O-RING Used as a gasket to seal the flashlight case against dust and moisture.
POLYCARBONATE Clear, tough, shatterproof, virtually unbreakable polymer used to make the lens in most eGear flashlights. Often hard coated for abrasion resistance.
POLYMER Material with a long chain molecular structure. Lightweight, highly durable, shock-resistant, non-conductive, and moldable in colors.
PRE-FOCUSED LAMP MODULE Lamp and reflector furnished and replaced as a unit. Permanently adjusted at the factory for optimum focus.
REFLECTOR Surrounds the lamp and directs and focuses the light rays in one direction. eGear reflectors are computer designed for optimum performance. UL Underwriters Laboratories, Inc. is a third-party testing organization that approves products for compliance to electrical specifications and for use in specified hazardous locations.
VOLT Unit of electrical potential. The potential difference between two points in an electrical system is called the voltage between those points.
WATT Unit of power. Electrical power can be calculated by multiplying voltage times amperage.
