Using a Dimming LED flashlight bulb for your flashlight, it is as simple as replacing the original incandescent bulb and also easy to replace the bulb with the light of all kinds of color like red, blue, green, UV and IR. These LED flashlight bulbs provide a nice smooth beam pattern with a great balance between throw and coverage, and you won’t lose your flood to spot focus with your flashlight. A '''flashlight''' (often called a '''torch''' outside North America+) is a portable hand-held electric light. The invention of the dry cell and miniature incandescent electric light bulbs made the first battery-powered flashlights possible around 1899. In addition to the general-purpose hand-held flashlight, many forms have been adapted for special uses. Early flashlights ran on zinc-carbon batteries+, which could not provide a steady electric current and required periodic "rest" to continue functioning.
Incandescent flashlights use incandescent light bulb+s which consists of a glass bulb and a tungsten+ filament.
The light output of an incandescent lamp in a flashlight varies widely depending on the type of lamp. LEDs can be significantly more efficient than incandescent lamps, with white LEDs producing on the order of 100 lumens for every watt, compared to 8-10 lumens per watt of small incandescent bulbs.
LED flashlights may consume 1 watt or much more from the battery, producing heat as well as light.
LEDs are highly efficient at producing colored light compared with incandescent lamps and filters.
A less common type of flashlight uses a High Intensity Discharge+ (HID) lamp as the light source.
Certain accessories for a flashlight allow the color of the light to be altered or allow light to be dispersed differently. Detachable light guides, consisting of rigid bent plastic rods or semi-rigid or flexible tubes containing optical fibers, are available for some flashlights for inspection inside tanks, or within walls or structures; when not required the light guide can be removed and the light used for other purposes. A penlight is a small, pen+-sized flashlight, often containing two AA batteries+ or AAA batteries+.
A headlamp+ is designed to be worn on the head, often having separate lamp and battery components.
Although most flashlights are designed for user replacement of the batteries and the bulb as needed, fully sealed disposable+ flashlights, such as inexpensive keyring+ lights, are made.
Diving lamps must be watertight under pressure and are used for night diving+ and supplemental illumination+ where surface light cannot reach. People working in hazardous areas+ with significant concentrations of flammable gases or dusts, such as mines, engine rooms of ships, chemical plants or grain elevator+s, use "non-incendive", "intrinsically safe" or "explosion proof" flashlights constructed so that any spark in the flashlight is not likely to set off an explosion outside the light. Inspection flashlights have permanently mounted light guides containing optical fibers or plastic rods.
Otoscope+s and ophthalmoscope+s are medical instruments that combine a hand-held light source and magnifying lenses for examination of the ear canal and eyes, respectively. As well as utilitarian flashlights, novelty, toy and ornamental portable electric lights have been made in a myriad of shapes; in the 1890s, one of the earliest portable battery light applications was a type of novelty porcelain tie pin+ with a concealed bulb and battery.
Secondary, rechargeable, types include lead acid+ batteries, NiMH+, NiCd+ batteries and lithium ion+ batteries. Flashlights used for extended periods every day may be more economically operated on rechargeable (secondary) batteries. One type of mechanically powered flashlight has a winding crank and spring connected to a small electrical generator+ (dynamo).
At least one manufacturer makes a rechargeable flashlight that uses a supercapacitor+ to store energy. A reflector with an approximately parabolic+ shape concentrates the light emitted by the bulb into a directed beam. The reflector may have a flat transparent cover to keep out dirt and moisture, but some designs have a plastic or glass "bulls-eye" lens to form a concentrated beam. A reflector forms a narrow beam called the "throw", while light emitted forward misses the reflector and forms a wide flood or "spill" of light.
The original 1890's flashlights used a metal ring around the fiber body of the flashlight as one contact of a switch+, and the second contact was a moveable metal loop that could be flipped down to touch the ring, completing the circuit. Electronic controls allow the user to select variable output levels or different operating modes such as pre-programmed flashing beacon or strobe modes. Metals may be drawn+ into a tubular shape, or tubular extruded stock can be machined to add threads for the head and tail cap, knurling for grip, and decorative and functional flats or holes in the body.
Metal cases provide better heat dissipation for the LED, but plastics are not electrically conductive and may resist corrosion and wear. Industrial, marine, public safety and military organizations develop specifications for flashlights in specialized roles.
Flashlights intended for use in hazardous areas+ with flammable gas or dust are tested to ensure they cannot set off an explosion. Regulations for ships and aircraft will specify the number and general properties of flashlights included as part of the standard safety equipment of the vessel.
The United States Army former standard MIL-F-3747E described the performance standard for plastic flashlights using two or three D cell dry batteries, in either straight or angle form, and in standard, explosion-proof, heat-resistant, traffic direction, and inspection types. In the United States, ANSI+ in 2009 published ''FL1 Flashlight basic performance standard''.
The FL1 standard requires measurements reported on the packaging to be made with the type of batteries packaged with the flashlight, or with an identified type of battery. The working distance is defined as the distance at which the maximum light falling on a surface (illuminance+) would fall to 0.25 lux+.
Run time is measured using the supplied or specified batteries and letting the light run until the intensity of the beam has dropped to 10% of the value 30 seconds after switching on. Impact resistance is measured by dropping the flashlight in six different orientations and observing that it still functions and has no large cracks or breaks in it; the height used in the test is reported. The consumer must decide how well the ANSI test conditions match their requirements, but all manufacturers testing to the FL1 standard can be compared on a uniform basis. ANSI standard FL1 does not specify measurements of the beam width angle+ but the candela intensity and total lumen ratings can be used by the consumer to assess the beam characteristics.

This product is discontinued with no replacement or is completely out of stock with no estimated in-stock date. This refers to the literal measure of the light-output of a particular light bulb, measured in the number of lumens. The "Bulb Type" is typically a combination of the style of bulb as well as the width of the bulb.
The filament is the style of fine wire that is heated electrically inside of an incandescent light bulb. Correlated Color Temperature (CCT) is a specification of the color appearance of a light bulb, relating its color to that of a reference source heated to a particular temperature, measured in degrees Kelvin (K). This refers to the number of Fluorescent or HID light bulbs that this particular ballast can light. Each bulb is built-in a high efficiency LED driver, which makes the bulb dimming stably by the flashlight original button switch. Usually, the source of the light is a small incandescent light bulb+ or light-emitting diode+ (LED).
Today flashlights use mostly incandescent lamps or light-emitting diodes and run on disposable or rechargeable batteries.
Because these early flashlights also used energy-inefficient carbon-filament bulbs, "resting" occurred at short intervals.
An LED flashlight may contain different LEDs for white and colored light, selectable by the user for different purposes. Translucent colored plastic cones slipped over the lens of a flashlight increase the visibility when looking at the side of the light. In some types the incandescent light bulb has an integral lens+ that focuses the light, so no reflector is built into the penlight. The battery pack may be attached at the back of the head or in a pocket to improve balance. The battery compartment of a dive lamp may have a catalyst to recombine any hydrogen gas emitted from the battery, since gas cannot be vented in use.
The flashlight may require approval by an authority for the particular service and particular gases or dusts expected. Another style has a lamp mounted at the end of a flexible cable, or a semi-rigid or articulated probe. Many smartphone+s have a button or software application available to turn up their screen backlights to full intensity, or to switch on the camera flash or video light, providing a "flashlight" function.
Primary (disposable) battery types used in flashlights include button cell+s, carbon-zinc batteries+ in both regular and heavy duty types, alkaline+, and lithium+. The choice of batteries will play a determining role in the size, weight, run time, and shape of the flashlight.
Some types of lithium primary cell can be stored for years with less risk of leakage compared with zinc-type batteries.
Flashlights designed for rechargeable batteries may allow charging without removing the batteries; for example, a light kept in a vehicle may be trickle-charged and always ready when needed. The lens or reflector cover must resist impacts and the heat of the lamp, and must not lose too much of the transmitted light to reflection or absorption.
A wide variety of mechanical switch designs using slide switches, rocker switches, or side-mounted or end-mounted pushbuttons have been used in flashlights.
Electronic controls may be operated by buttons, sliders, magnets, rotating heads, or rotating control rings.
Many other materials including drawn steel, plated brass, copper, silver, even wood and leather have been used. Typically, light output, overall dimensions, battery compatibility and durability are required to meet minimum limits. Flashlights approved for flammable gas areas will have markings indicating the approving agency (MSHA+, ATEX+, UL+ etc.) and symbols for the conditions that were tested. This voluntary standard defines test procedures and conditions for total light output, beam intensity, working distance, impact and water resistance, and battery running time to 10% of initial light output. Initial light output is measured with an integrating sphere+ photometer, 30 seconds after the light is switched on with fresh (or newly charged) batteries. Water resistance, if specified, is evaluated after impact testing; no water is to be visible inside the unit and it must remain functional. The light measurements are more directly related to the use of flashlights than is the nominal power input to the lamp (watts), since different LED and incandescent lamp types vary widely in the amount of light produced per watt+. Where two flashlights have similar total light (lumen) measures, the unit with the higher candela rating produces a more concentrated beam of light, suitable for lighting distant objects; it will also have a higher working distance. Usually, the source of the light is a small incandescent light bulb or light-emitting diode (LED).

Import charges previously quoted are subject to change if you increase you maximum bid amount. Also, the LED flashlight bulbs last longer than original incandescent bulbs, meaning you won’t have to replace your new LED flashlight bulb as often as you did with the standard one, and they are much brighter than any standard bulb.
A typical flashlight consists of a light bulb mounted in a reflector, a transparent cover (sometimes combined with a lens+) to protect the light source and reflector, a battery+, and a switch+.
Some are powered by the user turning a crank or shaking the lamp, and some have solar panels to recharge a battery. Consequently, they could be used only in brief flashes, hence the common North American name "flashlight". This was the first battery suitable for portable electrical devices, as it did not spill or break easily and worked in any orientation.
Some high-power incandescent flashlights use a halogen lamp+ where the bulb contains a halogen+ gas such as iodine+ or bromine+ to improve the life and efficacy of the bulb.
A two D-cell flashlight using a common prefocus-style miniature lamp will produce on the order of 15 to 20 lumen+s of light and a beam of about 200 candlepower+.
Goswami, '' Handbook of energy efficiency and renewable energy'', CRC Press 2007 ISBN 978-0-8493-1730-9, page 12-37 LEDs are also less fragile than glass lamps.
Colored LED flashlights are used for signalling, special inspection tasks, forensic examination, or to track the blood trail of wounded game animals.
HID lamps produce more light than an incandescent flashlight using the same amount of electricity. Such marshalling wands+ are frequently used for directing automobiles or aircraft at night. The external temperature rise of the flashlight must not exceed the autoignition+ point of the gas, so substitution of more powerful lamps or batteries may void the approval. Some resembled candlestick+s, with a bulb mounted at the top of a battery tube fixed to a flat base, with a handle.
A common combination is a slide switch that allows the light to be left on for an extended time, combined with a momentary button for intermittent use or signalling.

Flashlights may be tested for impact resistance, water and chemical resistance, and for the life span of the control switch. Flashlights for hazardous areas may be designed to automatically disconnect the lamp if the bulb is broken, to prevent ignition of flammable gas. Ratings are given in IP Code+ terms, where jet spray corresponds to IP X6, brief immersion to IPX7, 30 minutes immersion at 1 meter or more is IP X8; (the depth is reported if greater than 1 meter). Even the same LED or lamp in different optical systems will show different beam characteristics. If two lights have similar candela ratings, the light with higher lumen value will produce a wider beam and will light a wider area overall. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. The first mass-produced dry cell batteries came in 1896, and the invention of portable electric lights soon followed. This "electric device" designed by Misell was powered by "D" batteries laid front to back in a paper tube with the light bulb and a rough brass reflector at the end. In all but disposable or novelty flashlights, the bulb is user-replaceable; the bulb life may be only a few hours. One popular make+ of rechargeable focusing flashlight uses a halogen lamp and produces 218 lumens.
LED lamp+s have different spectra of light compared to incandescent sources, and are made in several ranges of color temperature+ and color rendering index+. Some flashlights electronically regulate the current through the LEDs to stabilize light output as the batteries discharge. The lamp will last longer and is more shock resistant than a regular incandescent bulb, since it lacks the relatively fragile electrical filament found in incandescent bulbs.
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.
Tactical lights must withstand the impact of recoil, and must be easily controlled while holding the weapon. Where used for inspecting the interior of tanks containing flammable liquids, the inspection lights may also be rated as flame-proof (explosion-proof) so that they cannot ignite liquids or vapors.
Many resembled lantern+s, consisting of a battery box with a handle and the lamp and reflector attached to the front. Lithium primary batteries are also useful at lower temperatures than zinc batteries, all of which have water-based electrolytes. Power-failure lights are designed to keep their batteries charged from a wall plug and to automatically turn on after an AC power failure; the power-failure light can be removed from the wall socket and used as a portable flashlight. Since voltages and currents are low, switch design is limited only by the available space and desired cost of production.
Luminous intensity+ is determined by measuring the brightest spot in the beam produced by the flashlight, in candela+s. An IP X8 rating by FL1 does not imply that the lamp is suitable for use as a diver's light since the test protocol examines function of the light only after immersion, not during immersion. The visibility of objects depends on many factors as well as the amount of light emitted by the flashlight.
A beam width (containing most of the power of the beam, or "hot spot") of a few degrees corresponds to a spot light, useful for searching for distant objects; beam widths of 20 degrees or more are described as flood lights, suitable for lighting a wide nearby area. It's not worth anything more than trying to upgrade the bulb for more brightness as the stock bulb produces a dim, yellow beam.
For example, 3V dimming LED flashlight bulbs can quickly convert any 2 cells flashlight with PR style flange bulbs from the standard incandescent to a bright white long lasting LED flashlight bulbs. Portable hand-held electric lights offered advantages in convenience and safety over (combustion) torch+es, candle+s and lantern+s. The company donated some of these devices to the New York City police+, who responded favorably to them.
Since the LED has a long life compared to the usual life of a flashlight, very often it is permanently installed.
LEDs maintain nearly constant color temperature+ regardless of input voltage or current, while the color temperature of an incandescent bulb rapidly declines as the battery discharges, becoming redder and less visible. However, they are much more expensive, due to the ballast+ circuit required to start and operate the lamp. 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. Electric lanterns are used for lighting the broad area immediately around the lantern, as opposed to forming a narrow beam; they can be set down on a level surface or attached to supports.
Lithium primary batteries have a lower internal resistance+ than zinc primary batteries and so are more efficient in high-drain flashlights. Solar powered flashlight+s use energy from a solar cell+ to charge an on-board battery for later use. Some manufacturers use a pebbled or "orange peel", instead of a smooth, reflector, to improve the uniformity of the light beam emitted. Since this is a measure of all the light emitted in a solid angle+ (the "cone" of light in a particular direction), the beam intensity is independent of distance. Typically even a flashlight beam with a small hot spot will have some light visible as "spill" around the spot. The electric lamp was odorless, smokeless, and emitted less heat than combustion-powered lighting. Some electric lanterns use miniature fluorescent lamp+s for higher efficacy than incandescent bulbs. An electronic control may also provide an indication of remaining battery capacity, or automatic step-down of brightness as the battery nears full discharge. A light directly pointed at an observer may be visible against a dark background for many times this distance, especially if the observer has night-vision equipment. A red filter helps preserve night vision after the flashlight is turned off, and can be useful to observe animals (such as nesting Loggerhead sea turtle+s) without disturbing them.
Flashlights using a "total internal reflection+" assembly have a transparent optical element (light pipe) to guide light from the source into a beam; no reflector surface is required. A desirable plastic for manufacturing flashlights allows for ease of molding and adequate mechanical properties of the finished flashlight case.
The album was first made available via free download on the band's MySpace profile on New Year's Day, 2007, and on compact disc on January 23 of the same year.
Dynamo-powered flashlights were popular during the Second World War since replacement batteries were difficult to obtain. For a given size of light source, a larger reflector or lens allows a tighter beam to be produced, while capturing the same fraction of the emitted light. Tag (game)+ Tag (also known as it, tig and many other names) is a playground game that involves one or more players chasing other players in an attempt to "tag" or touch them, usually with their hands. Other metals include copper+, stainless steel+, and titanium+, which can be polished to provide a decorative finish. Originally released on a trio of labels - Red Square in the USA, Sink & Stove and Silent Age Records in the UK - it was re-released with new sleeve artwork and packaging worldwide on Warp Records in 2004.
