Underwater LED Light Effective to 60 Meters - Larson Electronics

Magnalight Adds Multi-Purpose Underwater LED Light Effective to 60 Meters: Larson Electronics’ magnalight.com introduced the LEDEUL4 underwater LED light for wet area and submerged applications. At 12 watts, this LED light can be configured with visible, color or infrared LEDs and operates on 9-32 volts. Producing 720 lumens and measuring 4.25 inches in diameter and 1.25 inches thick, the underwater LED light is mounted with three through holes. The sealed junction box design eliminates the need for ‘bedding’ concerns and ensures watertight and moisture tight design.

Larson Electronics’ magnalight.com announced the addition of the new LEDEUL4 LED underwater light that is rated for operation to 60 meters in depth. The specialized housing design with sealed off junction box guarantees watertight operation above and below water. While many LED underwater lights can operate only underwater for cooling purposes, the LED-EUL4 underwater LED light can operate above or below water. Offered with several different LED options, including white, blue, green, amber and infrared LEDs, the LED-EUL4 underwater LED light, producing 720 lumens, has applications ranging from engine room illumination to underwater vessel inspection. The hockey puck shaped LED light features an aluminum housing with anti-corrosive coating, measuring 4.25 inches in diameter and 1.25 inches thick. Drawing only 1 amp on 12 volts and running on 9-32 volts, the versatile low voltage underwater LED light is suited for low voltage operation on line supply or battery banks.

“We designed this underwater LED light using the same principles as our explosion proof lights,” said Rob Bresnahan with Larson Electronics’ magnalight.com. Inside the aluminum housing we built in a small junction box. The power cable comes into the junction box and then we completely fill and seal the chamber completely with an epoxy material. This is the same principle of using and EYM and filling the junction box on an explosion proof light with Chico. Nothing inside the light can get out and nothing outside the light can get in, including air, particles, water and moisture. Also, by encapsulating the LED array in aluminum, the housing becomes its own heat sink. While many underwater LED lights are designed only for underwater use in order to stay cool, this LED light dissipates heat properly underwater or above water. We wanted this light to work not only for boating applications or submerged applications at depth, but also for engine rooms, wash down areas, tunnels, waterways and other applications where the lights may only be wet or occasionally submerged. For example, many times people rely on our site glass lights to inspect material levels within tanks and vessels. The LEDEUL4 can actually be placed in the tank to provide an internal light source, so the operators can use the site glass to observe and record without obstruction.

Rob continued, “Like many underwater LED lights, our LEDUL4 underwater light is encased in stainless steel. However, we choose aluminum for the new LEDEUL4 underwater LED light. While stainless steel is non-corrosive in saltwater, it is a poor conductor of heat, so the LEDUL4 is best limited to underwater use only. One of the main issues with LED lighting is creating a housing that holds the LED packages while dissipating the heat effectively. LEDs produce a lot of heat. Ironically, heat will also destroy the LEDs or dramatically reduce their life hours. By surrounding the LEDs with aluminum in addition to other unique design elements, we pull this heat of the LEDs to effectively preserve their longevity. The aluminum housing enables the use of the LEDEUL4 underwater LED light in submerged or normal applications. To prevent corrosion, we use same anti-corrosive coatings that are used on aluminum boats, US Navy aircraft carriers and other seagoing craft that use a lot of aluminum. We choose a specific type of aluminum and specific coatings designed for corrosive environments. This coating doesn’t give as attractive a finish as our existing underwater stainless steel LED lights, but we see broader industrial and military applications for the aluminum based underwater LED light. For example, we offer red, green, amber and blue LEDs and even infrared LEDs at 850nm and 940nm wavelengths within this LED light fixture. Our initial orders have been for illuminating junctions in water control tunnels, red light illumination in US Naval engine rooms, fountain lighting, chemical tank level inspection and underwater boat inspection lights for the Coast Guard. While we see the traditional LED boat light applications, we have a versatile LED light source for all kinds of commercial, industrial and security oriented applications. The light will operate at 180 feet below the water’s surface or inside a 100 degree engine room equally well. In fact the light is designed to operate at ambient temperatures from -20 degrees C to 85 degrees C,” Rob concluded.

Genepax has Unveiled a Car that runs only on Water as Fuel!

Genepax, a Japanese venture company has unveiled a car that runs on water as Fuel. All it requires is a litre of water. In fact, any kind of water to be exact, whether its river, rain, sea water, or even Japanese tea sounds funny, ofcourse that's cent percent true..

Genepax Co Ltd explained the technologies used in its new fuel cell system "Water Energy System (WES)," which uses water as a fuel and does not emit CO2. "The main characteristic of this car is that no external input is needed. The car will continue to run as long as you have a bottle of water inside for you to add from time to time," said Kiyoshi Hirasawa, Chief Executive Officer of Genepax, after he proudly announced the company's invention.

As per the claims it runs only on a 300W "Water Energy System (WES)" where WATER is the only FUEL. Once water is poured into the water tank at the back of the car, the newly invented energy generator takes out the hydrogen from the water, releases electrons and finally generates electrical power. According to Genepax, the main feature of the new system is that it uses the company's membrane electrode assembly (MEA), which contains a material capable of breaking down water into hydrogen and oxygen through a chemical reaction.

"We highly recommend our system since it does not require you to build up an infrastructure to recharge your batteries, which is usually the case for most electric cars," said Hirasawa, who is hoping to advertise the car in time for the upcoming G8 Summit in Hokkaido, Japan.

According to the company, 1 liter of water keeps the car running for about an hour with a speed of 80 kilometers or 50 miles an hour. The company has applied for a patent and is hoping to collaborate with Japanese automobile manufacturers to mass manufacture their invention in the very near future. As fuel prices continue rising and people look for greener alternatives, companies globally are trying to come up with alternatives.

Though the company did not reveal the details, it "succeeded in adopting a well-known process to produce hydrogen from water to the MEA," said Hirasawa Kiyoshi, the company's president. This process is allegedly similar to the mechanism that produces hydrogen by a reaction of metal hydride and water. But compared with the existing method, the new process is expected to produce hydrogen from water for longer time, the company said.

With the new process, the cell needs only water and air, eliminating the need for a hydrogen reformer and high-pressure hydrogen tank. Moreover, the MEA requires no special catalysts, and the required amount of rare metals such as platinum is almost the same as that of existing systems, Genepax said.

Unlike the direct methanol fuel cell (DMFC), which uses methanol as a fuel, the new system does not emit CO2. In addition, it is expected to have a longer life because catalyst degradation (poisoning) caused by CO does not occur on the fuel electrode side. As it has only been slightly more than a year since the company completed the prototype, it plans to collect more data on the product life.

At the conference, Genepax unveiled a fuel cell stack with a rated output of 120W and a fuel cell system with a rated output of 300W. In the demonstration, the 120W fuel cell stack was first supplied with water by using a dry-cell battery operated pump. After power was generated, it was operated as a passive system with the pump turned off.

This time, the voltage of the fuel cell stack was 25-30V. Because the stack is composed of 40 cells connected in series, it is expected that the output per cell is 3W or higher, the voltage is about 0.5-0.7V, and the current is about 6-7A. The power density is likely to be not less than 30mW/cm2 because the reaction area of the cell is 10 x 10 cm.

Meanwhile, the 300W fuel cell system is an active system, which supplies water and air with a pump. In the demonstration, Genepax powered the TV and the lighting equipment with a lead-acid battery charged by using the system. In addition, the 300W system was mounted in the luggage room of a compact electric vehicle "Reva" manufactured by Takeoka Mini Car Products Co Ltd, and the vehicle was actually driven by the system.

Genepax initially planned to develop a 500W system, but failed to procure the materials for MEA in time and ended up in making a 300W system.

For the future, the company intends to provide 1kw-class generation systems for use in electric vehicles and houses. Instead of driving electric vehicles with this system alone, the company expects to use it as a generator to charge the secondary battery used in electric vehicles.

Although the production cost is currently about ¥2,000,000 (US$18,522), it can be reduced to ¥500,000 ($5,000) or lower if Genepax succeeds in mass production. The company believes that its fuel cell system can compete with residential solar cell systems if the cost can be reduced to this level.

High-Tech HydroWorx to Help NASA Astronauts

NASA has turned to HydroWorx's aquatic therapy pools for help with the conditioning and health of its astronauts. The Johnson Space Center in Houston, Texas is where U.S. astronauts live and train; the facility is working on a project called the Center for Space Flight Performance and Research. This high-tech health center will incorporate HydroWorx hydrotherapy pools to keep its space travelers fit and healthy.

Well HydroWorx has specialized in designing, manufacturing and marketing the worlds finest water therapy and conditioning equipment for the home, sports, healthcare, eldercare and fitness markets. The company's core technologies are centered upon maximizing the therapeutic properties of water to accelerate rehabilitation and provide a nearly stress free medium for exercise.

The Center plans to include a HydroWorx 1200 Series underwater treadmill pool, a ThermalPlunge hot tub and a PolarPlunge cold tub.

Have look at this Video to get an idea of actual aquatic therapy



The 1200 Series swim spa is a quantum leap forward in aquatic therapy and wellness. Its ground-breaking design allows healthcare professionals with limited space to enjoy the benefits of our aquatic therapy and exercise in a compact package. The entire pool floor is fully adjustable in height, which will allow the astronauts to simply stand or sit on the treadmill while it is flush with the surrounding floor and be lowered into the water. The pool depth can reach 6' within 30 seconds, so the astronauts' coaches and physical therapists can strategically unload 20% to 90% of their bodyweight by raising or lowering the treadmill to manipulate water depth. This comes in handy training for zero gravity.

The astronauts will be able to walk or run against resistance jets, which are essential for exercise, therapy, rehabilitation, swimming, or deep tissue massage. These jets are adjustable to up to 200 different water speeds. Attaching a massage hose harnesses the force of a jet into a focused stream, creating a deep, wide band of pressure for subcutaneous, therapeutic penetration and myofascial release.

All functions of the HydroWorx pool are computer monitored and will be able to be recorded to validate and track astronaut recovery and progress.

The 1200 Series pool will include three underwater cameras and a flat screen viewing monitor which will greatly enhance the NASA therapist's diagnostic capabilities when evaluating an astronaut's underwater gait pattern.

NASA's awareness of the benefits of hot and cold water therapy prompted their purchase of the other HydroWorx pools for the facility. The hot water (94º- 110º) and cold pools (50º) will allow U.S. astronauts to speedily recover from strain and exercise. Strategic pool jets can be positioned in any configuration for soothing massage or trigger point patterns. Attaching a massage hose harnesses the force of a jet into a focused stream, creating a deep, wide band of pressure for hot or cold subcutaneous, therapeutic penetration and myofascial release.

The thermal heating units are engineered to distribute warm or hot water to relax tight muscles and stimulate the release of endorphins. This will aid astronauts in stretching and warming-up pre-activity or soothing tired muscles post-activity.

HydroWorx's Polar Chiller systems maintain water temperatures at a therapeutic 50º to control joint inflammation and enhance recovery by constricting muscle fibers to pump out lactic acid.

With the addition of HydroWorx aquatic therapy pools in the Center for Space Flight Performance and Research, NASA's astronauts' fitness and health should be out of this world.

Run your Car on Regular Tap Water, Yes this true

New Technology Allows You to Convert Your Car to Run on Regular Tap Water - Skyrocketing Gas Prices are Causing Frustrated Car and Truck Owners to Search for Fuel Alternatives

Well the price of oil at an all-time high, car owners around the world are searching for ways to save money on gas. A new report teaches car owners how to run a combustion engine car or truck on water, saving huge money at the gas pump. View this video describing technology involved.



Oil is the lifeblood of America's economy. Americans drive and fly more than any other nation in the world, contributing to rising oil prices. America uses a full 25% of the world's oil, mostly for transportation.

Much of the U.S. oil supply comes from overseas sources, making the U.S . dependent on other nations to supply the lifeblood of the transportation system. According to the U.S. Department of Energy, the remaining U.S. oil fields are becoming increasingly costly to produce because much of the easy-to-find oil has already been recovered.

With some industry experts predicting prices will top $500 for a barrel of oil within a few years, it appears there is no end in sight for gas price increases, making it all the more important to find alternative fuel sources, such as water.

The combination of swelling oil prices, a slowing global economy, and increased unemployment, are causing car owners to explore alternatives to spending money on new, more energy-efficient cars. While water has long been considered as an alternative fuel source, without the recent rise in gas prices, car owners were not motivated to explore the technology.

The technology behind using water to run a car includes using the battery in your car to take water and separate it into "HHO," which stands for Hydrogen, Hydrogen, and Oxygen. This gas burns very effectively and keeps the power of the Hydrogen, but it stays stable, just like water. Only a small amount of water is needed, since a lot of HHO gas can be made from just a quart of water. This gas is actually more potent than regular gasoline, so it can also enhance most cars' performance and improve gas mileage.

American's are reluctant to give up their gas-guzzling SUVs, so must seek ways to reduce their gasoline costs. According to the Energy Information Administration "Record crude oil prices are pushing current and expected gasoline prices to record levels." And predictions show no slowing of the upward trend in gas prices, affecting every part of the world economy. Learning to run a car on water is an option whose time has come.
