Flashlights Reviewed - Times OnLine

Led-Lenser-Police-Tech-Focus.jpg

The Times OnLine have published a review of the Led Lenser Police Tech Focus, Inova 24/7, Princeton Tec Genesis, Mag-lite 2D 3W Led, Ring Cyba-lite N16 Xenon and the Gerber Omnivore flashlights. 'All our torches claimed to be at least water resistant, so we gave them a 30-second shower to simulate a heavy downpour - the sort of conditions in which you'll inevitably have to change a flat tyre. In addition, we dropped them from a height of 3ft onto a hard floor to see how they stood up to some typical rough and tumble. All shone through, which meant we could then evaluate their beam performance, build quality and availability of accessories, such as a pouch and belt clip.'

All About LEDS And The Future Of Lighting

An article over at Flyxia.com traces the evolution of LED technology from the early beginning through to the present where it appears to be on the cusp of becoming the primary feature in most lighting applications. ‘The advantages of adopting LEDs to provide sole source lighting for every application are significant. LEDs emit virtually no heat (wasted energy) and are “in fact… cool to the touch” unlike incandescent light bulbs. They are also more durable (encased in a hardened shell and resistant to vibration and shocks) than and last up to 50 times longer than traditional incandescent and fluorescent bulbs ( some can be used for up to 10 years), and they “use a greater proportion of the electricity flowing through them” translating into “savings for consumers.” [9] According to the U.S. Department of Energy, “widespread adoption of LEDs could cut U.S. consumption of electricity for lighting by 29%”[10] since they require less energy to function and by their nature, reduce the amount of air conditioning needed to keep areas cool and comfortable.’

TechRepublic's Hands-on With A Lightsaber

lightsaber.jpg

CNET have republished the review of TechRepublic's hands-on "Cracking open" of a lightsaber. 'Turning the saber over, we find more design characteristics (belt loop near the blade, two silver control studs) that tell the hard-core Star Wars fan this could only be Darth Vader's lightsaber. Such attention to detail and faithfulness to the originals are what we've come to expect from Lucasfilm licensees. Although it was too quick to photograph, turning the saber on activates the red lights in the blade in stages from bottom to top, giving the same ignition and effect as in the movies. Naturally, turning the saber off causes the lights to extinguish in sequence from top to bottom as well.'

On Choosing the appropriate flashlight.....,

PR-GB.com have republished an article which offers some useful tips on selecting the most suitable flashlight to fit the occasion. 'It is necessary to purchase different varieties of flashlights for different uses. If you want to save on costs and think a single flashlight will do, you need to do some rethinking! For one, different intensities of light are required within and around the house and while traveling by your vehicle. If you have a single flashlight at home, you may also forget to carry it while leaving the house. Therefore, invest in a few and they are sure to bail you out in an emergency!'

How is your emergency lighting inventory?

CCrane-Calamity-Kit.jpg

The Arkansas Democrat-Gazette details a useful plan for equipping your household with an affordable mix of emergency lighting devices. 'Flashlights that provide five minutes of light when shaken or hand-cranked for 30 seconds. They’re handy for long-term power failures. Waterproof flashlights, necessary in floods. Lanterns that illuminate entire rooms. You can take them on camping trips, too. The technology behind flashlights and lanterns has improved, says Betsy Laakko, a representative for Energizer, the flashlight and battery manufacturer based in St. Louis. Most use a cluster of lightemitting diodes (LEDs ) that shine brighter and last longer than before. The company makes a room-lighting lantern that can1 last 1 / 2 months using one set of batteries.'

Batteryless [Shake] Flashlight Operation Explained

Shake-Flashlight.jpg

DR. KNOWLEDGE writing over at The Boston Globe has posted an explanation on just how the Shake Flashlight produces illumination. ‘The main idea behind batteryless flashlights is to use the physical motion of the flashlight itself to provide the energy to light up the bulb -- that is, you have to shake it. What happens is always a variant on the following basic idea: If you have a coil of wire and drop a magnet through it, this will make some electricity flow through the coil and whatever it's attached to. This electricity can be stored to power a light bulb.’

PLEDS: The next generation of LEDs

Two researchers at the UCLA Henry Samueli School of Engineering and Applied Science have recently achieved the highest lumens per watt ever recorded for a red phosphorescent LED in their ongoing efforts to improve the illumination on future LED flat panel TVs. 'In Yang and Huang’s new polymer light emitting diodes, the devices have a very simple single-layer structure, generated by a much cheaper solution process. The new LED, or more precisely PLED, developed by the two UCLA engineers uses a polymer powder and liquid mixture added to a previously top-secret material developed by the Canon company to create a paint-like product. The product is used to coat a layer of glass, and a charge is added. The end result is a slim single layer of glass with two electrodes.'

LEDS set to dominate lighting applications in the future

LED-Bulb.jpg

Technology Review reports on the increasing use of LEDS and the consequent decline in popularity of the traditional light bulb. ‘LEDs, which are small chips usually encased in a glass dome the size of a matchstick head, have been in use in electronics for decades to indicate, for example, whether a VCR is on or off. Those LEDs were usually red or green, but a scientific breakthrough in the 1990s paved the way for the production of LEDs that produce white light. Because they use less power than standard incandescent bulbs, white LEDs have become common in flashlights.’

The No.1 option for improving energy efficiency - Ban Incandescent Bulbs!

Ban-incandescent-bulbs.jpg

Matt Prescott writing in his View Point on the BBC World Service posits the argument that doing away with "inefficient and obsolete technology " - re; incandescent light bulbs, would be a significant first step towards the overall improvement of energy efficiency campaigns. ' Listening to most politicians, you would think the world's energy problems can be solved only by building ever bigger power stations and burning ever more fuel.Not so; and it certainly cannot solve the coming climate crisis. After turning off unnecessary pieces of equipment, improved energy efficiency is the cheapest way for developing countries to maximise their use of limited energy supplies, and for developed countries to achieve cuts in their carbon dioxide emissions.'

Flashlight or Headlamp! Which do you prefer?

There is an interesting discussion (thread) over at BackPacking Light.com on the pros and cons of using a flashlight vis a vis a headlamp. The issue is professionally outlined in a rather long but informative series of posts. 'Why a headlamp and not a flashlight? In some respects the answer is obvious, viz. "hands free" operation. For the UL backpacker, this is a compelling reason, especially if one's hands might be otherwise occupied with either trekking poles or ice axe (for some, nearly full-time) or with scrambling (a part-time endeavor, generally). I'll leave climbing and mountaineering out of the picture because what I personally know of these could fill a thimble!'

Review: Multi-color LED Flashlight - Gear Diary

Multi-color-LED-Flashlight.jpg

A review of the Multi-color LED Flashlight available from ThinkGeek has been posted over at the Gear Diary. 'Lets take a look at the outside of the flashlight first. Measuring 4.9″ in length and 1.25″ in diameter, makes the flashlight for a good size pocket light. The unit has a heavy duty appearance and feel to it, almost like the tactical type flashlights. It is made of aluminum with a silver finish. The aluminum makes it weigh very little even with the batteries installed. There are also grips molded into the body for holding the flashlight and unscrewing the tail cap. Like other tactical flashlights, there is a on/off push button switch in the tail cap.

CNET: Lighting The Future With LEDS

Lighting-The-Future-With-LEDS.jpg

CNET reports on the increasing use of LEDS as replacements for incandescent bulbs in mainstream lighting applications. 'Right now, consumers and businesses can buy a light-emitting diode, or LED, that provides about the same level of illumination as an energy-hogging conventional 60-watt lightbulb, Steven DenBaars, a professor of material science at the University of California Santa Barbara, said at the SEMI NanoForum, taking place here this week. A principal advantage of the LED: It lasts about 100,000 hours, far longer than the conventional filament bulb.Unfortunately, the LEDs that can perform this task cost about $60, he said. (Prices vary on the Internet.) But prices have been declining by 50 percent a year, so two years from now the same LED should cost around $20'

Flashlights Arouse Suspicion

With the heightened security awareness prevailing at present, it would appear travelers are going to have to exercise extreme caution in just how flashlights packed in their luggage bags. Leslie Griffy, writing for Mercury News, reports on a peculiar incident involving two "mysteriously connected" flashlights which triggered a "security alert" at Mineta San Jose International Airport. 'About 100 people were evacuated from a terminal at Mineta San Jose International Airport Saturday morning after screeners discovered a suspicious but ultimately harmless electrical device in a traveler's carry-on luggage. According to airport spokesman Rich Dressler, the south concourse of Terminal C was evacuated for about a half hour starting about 8 a.m. Saturday.'

Battery Power Out Of Control?

Irrespective of manufacturers’ claims as to the strengths and/or capabilities of various consumer-type batteries, it would be prudent especially in light or recent incidents, to exercise some thought on the portable power supplies which drive the gadgets we have come to rely on for much of our communication and entertainment. John Dodge writing in the Electronic Business gives a preview of the increased capacity likely to be contained in future batteries currently under development. ‘We shouldn’t take batteries for granted. They start our cars and power our computers, pacemakers, flashlights, hearing aids and cell phones. And that’s only what they do today. Tomorrow, they’ll likely be central to vehicle propulsion and will power any number of yet-to-be invented devices. They’ll store energy when intermittent power sources such as wind are blowing. Batteries are important.’
