A common use of a strobe flash is to optimize a car engine's efficiency at a certain rotational period by directing the strobe-light towards a mark on the flywheel on the engine's main axle. The strobe-light tool for such ignition timing is called a timing light. Strobe lighting has also been used to see the movements of the vocal cords in slow motion during speech, a procedure known as video-stroboscopy.

A typical commercial strobe light has a flash energy in the region of 10 to 150 joules, and discharge times as short as a few milliseconds, often resulting in a flash power of several kilowatts. Larger strobe lights can be used in “continuous” mode, producing extremely intense illumination.

The strobe light was popularized on the club scene during the 1960s when it was used to reproduce and enhance the effects of LSD trips. Ken Kesey used strobe lighting in coordination with the music of the Grateful Dead during his Acid Tests. In early 1966, Andy Warhol's lights engineer, Danny Williams, pioneered the use of multiple stroboscopes, slides and film projections simultaneously onstage during the 1966 Exploding Plastic Inevitable shows, and at Bill Graham's request, Williams built an enhanced stroboscopic light show to be used at Fillmore West.

A strobe light or stroboscopic lamp, commonly called a strobe, is a device used to produce regular flashes of light. It is one of a number of devices that can be used as a stroboscope. The word originated from the Ancient Greek στρόβος (stróbos), meaning "act of whirling".

These lenses come in a variant of colors, mainly clear, yellow, amber, red, blue, and green. The lens color can affect the intensity of light.[5]

The Baader Laser Collimator was easy to use , and gives additional confirmation of the collimation provided by the collimation cap . It will be especially useful to tweak the collimation ( if necessary) when the telescope is on the mount at night by small adjustment of the primary mirror screws . I have no issues with this product ..

Note 2: For any laser collimator to be effective it needs to be fitted to a well-made focuser. The regular rack-and-pinion style focuser fitted to many beginner/intermediate telescopes lacks precision and rigidity. If in doubt please contact us for advice.

Strobelights are often used to give an illusion of slow motion in nightclubs and raves, and are available for home use for special effects or entertainment.

This is the best Budget Laser Collimator I have used. It's not going to break the bank. Most important of all, the collimator fires a single tight round laser dot. I have found it very good when collimating my F5 Newtonians.

LED strobe beacons consist of a base, a LED or group of LEDs, and a cover. A solid state flash controller is located within the base, which allows the LED beacon to operate in a variety of flash patterns.[6]

The Baader Laser Collimator is a great peice of kit, well engineered, and make's collumating a breeze. It has been designed well so not to loose columation itself! Only slight negative is that the batteries are very small and will sometimes flip when trying too drop them in toget the right polarity.

Strobe lights are often used for aircraft anti-collision lighting both on aircraft themselves and also on tall stationary objects, such as television and radio towers. Other applications are in alarm systems, emergency vehicle lighting, theatrical lighting (most notably to simulate lightning), and as high-visibility aircraft collision avoidance lights. They are still widely used in law enforcement and other emergency vehicles, though they are slowly being replaced by LED technology in this application, as they themselves largely replaced halogen lighting.[citation needed] Strobes are used by scuba divers as an emergency signaling device.[7]

Note 1: Prior to using a laser you will need to first check/set a Newtonian telescope's secondary mirror using a sight-tube. Fortunately once set it rarely needs further adjustment.

A strobe beacon is a flashing electric lamp used in a variety of industries as an attention-getting device, either to warn of possible hazards, or to attract potential customers. Strobe beacons are similar to rotating beacons, but are more energy efficient, and with no moving parts, are more reliable and less likely to break.

Some strobes even offer continuous mode of operation whereby the arc is sustained, providing extremely high intensity light, but usually only for small amounts of time to prevent overheating and eventual breakage of the flash tube.

As best as I have been able to tell, it arrived in good collimation itself (adjusting its rotation in the focuser did not change the location of the dot on the primary mirror), and the results in my images on an F4 scope reveal it is genuinely creating a well collimated setup, as the tolerance at F4 is rather tight.The only way it would be better, is if the laser were a bit brighter, and if the beam were more consistently sharp when showing up on the acryllic screen when it returns from the secondary mirror. Sometimes it shows up as a nice dot and other times it seems rather smudgy. Still, results speak for themselves and it seems to be a very good product.

Gas strobe beacons include Xenon flash lamp and halogen varieties. Gas strobe beacons consist of a gas-filled tube surrounded by a lens. When electricity is applied, the tube flashes and is magnified by the lens, and a 360 degree light is emitted. The intensity of the light depends on the amount of electricity provided.[3][4]

The light source is commonly a xenon flash lamp, or flashtube, which has a complex spectrum and a color temperature of approximately 5,600 kelvins. To obtain colored light, colored gels may be used.

Rapid flashing of a stroboscopic light can give the illusion that white light is tinged with color, known as Fechner color. Within certain ranges, the apparent color can be controlled by the frequency of the flash. Effective stimuli frequencies go from 3 Hz upwards, with optimal frequencies of about 4–6 Hz. The colours are an illusion generated in the mind of the observer and not a real color. The Benham's top demonstrates the effect.[11] [12] [13] [14]

A strobe without a capacitor storage device simply discharges mains voltages across the tube once it's fired. This type of strobe requires no charging time and allows for much quicker flash rates, but drastically reduces the lifetime of the flash tube if powered for significant periods of time. Such strobes require a form of current limiting, without which the flash tube would attempt to draw high currents from the electricity source, potentially tripping electrical breakers or causing voltage drops in the power supply line.

Having struggled with an ordinary Cheshire I decided to try a laser after seeing videos. Adjusting the secondary was a breeze, but due to the flat screen it took two of us to collimate the main mirror on my 12 inch Newtonian. The red dot on the screen was nice and bright and showed up clearly on the centre of the main mirror for the secondary adjustment. With lasers you can make the small adjustments as the locking nuts are tightened and re -check so easily any time. I didn't time it but it felt that the whole job took only a couple of minutes. Brilliant.

Strobe lights usually use flashtubes with energy supplied from a capacitor, an energy storage device much like a battery, but capable of charging and releasing energy much faster. In a capacitor-based strobe, the capacitor is charged up to around 300 V. Once the capacitor has been charged, to trigger the flash a small amount of power is diverted into a trigger transformer, a small transformer with a high turns ratio. This generates the weak but high-voltage spike required to ionize the xenon gas in a flash tube. An arc is created inside the tube, which acts as a path for the capacitor to discharge through, allowing the capacitor to quickly release its energy into the arc. The capacitor's energy rapidly heats the xenon gas, creating an extremely bright plasma discharge, which is seen as a flash.

Special calibrated strobe lights, capable of flashing up to hundreds of times per second, are used in industry to stop the appearance of motion of rotating and other repetitively operating machinery and to measure, or adjust, the rotation speeds or cycle times. Since this stop is only apparent, a marked point on the rotating body will either appear to move backward or forward, or not move, depending on the frequency of the strobe-flash. If the flash occurs equal to the period of rotation (or an even multiple, i.e. 2*π*n/ω, where n is an integer and ω the angular frequency), the marked point will appear to not move. Any non-integer flash setting will make the mark appear to move forward or backward, e.g. a slight increase of the flash frequency will make the point appear to move backward.

The Baader Laser Collimator has a precision-etched reticule featuring hundreds of tiny cross-hairs which light up brightly when the reflected laser beam touches them.  Easily visible from any viewing angle.  Even if the optics are off to a large degree, the reflected beam can be traced right through to the reticule and the telescope optics adjusted until the beam falls back on itself.

The origin of strobe lighting dates to 1931, when Harold Eugene "Doc" Edgerton employed a flashing lamp to make an improved stroboscope for the study of moving objects, eventually resulting in dramatic photographs of objects such as bullets in flight.

EG&G [now a division of URS] was founded by Harold E. Edgerton, Kenneth J. Germeshausen and Herbert E. Grier in 1947 as Edgerton, Germeshausen and Grier, Inc. and today bears their initials. In 1931, Edgerton and Germeshausen had formed a partnership to study high-speed photographic and stroboscopic techniques and their applications. Grier joined them in 1934, and in 1947, EG&G was incorporated. During World War II, the government's Manhattan Project made use of Edgerton's discoveries to photograph atomic explosions; it was a natural evolution that the company would support the Atomic Energy Commission in its weapons research and development after the war. This work for the Commission provided the historic foundation to the Company's present-day technology base.[8]

Sometimes strobe lighting can trigger seizures. Several public incidents of photosensitive epilepsy have occurred. Most strobe lights on sale to the public are factory-limited to about 10–12 Hz (10–12 flashes per second) in their internal oscillators, although externally triggered strobe lights will often flash as frequently as possible. Studies have shown that the majority of people that are susceptible to the strobing effects can have symptoms, albeit rarely, at 15 Hz-70 Hz. Other studies have shown epileptic symptoms at the 15 Hz rate with over 90 seconds of continuous staring at a strobe light. Many fire alarms in schools, hospitals, stadiums, etc. strobe at a 1 Hz rate.

Internally triggered Strobotrons (light-output optimized thyratrons) were available[9] as well as flood-beam-CRT-type, grid-controlled Vacuum stroboscopic light sources with fast phosphors.[10]

The duration of a single flash depends on the particular strobe being used and its settings. Strobes for studio lighting often have a range of power settings. For a given strobe, higher light output corresponds to a longer flash duration. For example, the Flashpoint Rapid 1200 HSS Monolight [1] has a flash duration as long as 5.6 ms (1/180 sec) at its highest output setting, or as short as 68 μs (1/14,814 sec) at its lowest output setting. Strobes with significantly shorter flash durations are commercially available, some with flash durations less than 1 μs. For example, the SPOT strobe by Prism Science Works provides a flash duration of order 0.5 μs[2]
