While this looks like a typical tactical LED flashlight, it is really Marinebeam's new and patented Ultra Long Range LED Illuminator Spotlight, which has a 4° beam and an ANSI-FL1 rated usable range distance of over 650 meters. If you have recently seen the ads on TV and Facebook about LED Flashlights that have military technology, or claim some super amount of lumens, they are truly toys compared to this light.
This ultra-collimated beam illuminator is made specifically as a handheld searchlight for spotting buoys, channel markers, crab pots, etc, at night. It is also useful for search-and-rescue operations, and for attracting attention of rescue personnel, aircraft, etc. The best part is that it lasts up to 12-hours, and there are no expensive or unreliable batteries - just 3 standard D-cells. If you have previously used portable Q-beam™ type spotlights on-board, you know that in order to use one effectively you have to send someone up to the bow to deploy it. So, they really aren't practical to quickly use from the cockpit, because all of the spillover light is reflected back into your eyes, which destroys your night-vision. The light beam from the Illuminator RLT is super collimated, and has no spillover light, so it is easily and quickly deployed from the cockpit, and the beam doesn't reflect back and ruin your night-vision.
It uses Wavien's remarkable patented invention called Recycled Light Technology (RLT), which is a simple, cost-effective way to dramatically increase the brightness and efficiency of standard LEDs. Wavien's main business is producing a handheld non-lethal LED light weapon called StunRay, which uses the same RLT invention to create light so bight that it temporarily blinds, stuns, and disorients an attacker. Our light uses the passive RLT component technology to increase the usable light output of its Cree LED by over 2.0 times. It does so by collecting the high-angle spill-over light that would normally be wasted, and redirects this light back onto the emitter surface. This re-excites the LED phosphor generating more light, further collimating it, and directing it down range. The usable LED light output is significantly boosted by the RLT, with no additional LED input power required and no change in LED lifetime. No other flashlight can do this. This candela-compounding is only possible with RLT.
Notice that nowhere in this description, or in the specs, will you find any outrageous lumen claims. That is because the long-range illuminator, uses its efficiency to gain beam distance, not battery draining LED power. In fact, the best part of the technology is that the power consumption and lumen output of this lamp does not need to be unnecessarily high, because the lumen-density (Candela) is off the charts. So, DO NOT just use our lumen figures to compare this lamp's output or its long range illumination capabilities. As a point of reference, the Streamlight Stinger HPL, which is a high-end, high lumen LED flashlight, with a specialized long-range reflector, has an efficiency of only 64 Candela/Lumen. By contrast, the Marinebeam Long-Range Illuminator has an efficiency of more than 166 Candela/Lumen, so it can make two-and-a-half times more brightness with much less power, meaning fewer batteries, and more battery life.
The typical LED flashlight has about 50° of wasted spill over light, while the Marinebeam Illuminator flashlight has no spill-over light whatsoever. By redirecting and recycling all of the normally wasted light energy, we can throw all of the beam energy down range. The Illuminator not only benefits from a lack of wasted spill-over light, but also from it's ultra narrow 4° beam angle, which produces a defined spot which is only about 60 feet in diameter at 300+ yards. It is a true spot light.
For a further detailed explanation of how this light beats all other LED flashlights, read our How RLT Works document, our watch the detailed 10 minute video below.
The best analogy to understand how we can make more brightness with less power is a laser beam. Handheld lasers have incredible distance capabilities, even when using very, very low power (tenths of a Watt). This is also true of Marinebeam's illuminator. We can get an ANSI/FL1 beam distance of over 690 Meters and a very compact spot size, with only 600 lumens. The spot is so precise and well defined that when it is shined upon a wall, you will actual see an image of the LED chip itself projected. The perimeter of the spot is a perfectly crisp line, and all of the light inside the spot is high energy light, and there are no halos, rings, or dark spots like you would find on a typical searchlight. This image, and its intensity, are not just the result of a collimating aspherical lens, but rather a result of the the RLT optic recycling and boosting the entire amount of spillover light and presenting it to the lens.
The ANSI/NEMA FL1 Standard defines the "maximum beam distance" as the distance (in meters) at which the light will land 0.25 lux of illuminance. So, that is the equivalent light, at 690 meters, of a full moon in an open field on a clear night. It is calculated by taking the square root of the peak candela divided by 0.25.
We have all seen long range beams, but imagine standing on the tee box of a long Par 5 at your local golf course, on the darkest night, and being able to illuminate the green and the pin with just this handheld LED light! The light hitting the pin 600+ yards away would also be enough to take a nice clear picture or video of it with your cell phone camera. Now imagine that you can keep it illuminated for 8 to 12 hours with the standard off-the-shelf D cell batteries. This is all possible with this Illuminator.
The Marinebeam Ultra Long Range LED Illuminator is tough and impact-resistant, with a rugged aluminum casing, which resists rust and corrosion. It also features a long lasting Cree XML2 LED made by Cree USA, a world leader in LED technology.

For those techies that really want to understand flashlight "throughput", and why Recycled Light Technology makes any LED brighter, the 10 minute video below goes into the throughput problems of traditional flashlights. It explains how the patented RLT technology works inside our flashlight to solve the throughput problem, and how it allows the maximum amount of light from the minimum amount of lumens.
We don't know about you, but when we reach for a flashlight on board, we want it to work. Rechargeables are great, but can take a long time to charge, typically have less capacity, and are more expensive to keep multiple spares around. Our experience is that rechargeables don't seem to have the shelf-life we've come to expect from beefy and readily available D-cells. Nothing is worse than grabbing a dead flashlight and then having to wait 8 hours for a recharge. Li-Ion batteries are also now difficult and expensive to ship, almost exclusively of questionable Chinese origin, and can be very dangerous to charge aboard you boat in hot climes. Besides, because our lamp is so efficient, a good set of D-Cells should last you the whole season.
* Why does it take so long to produce these, and why is Marinebeam always selling out?
Initially, Marinebeam was caught off-guard by the significant press and viral social media publicity that our Illuminator received. This quickly lead to a "Shark Tank" phenomena which we were unprepared for. Shortly thereafter, our US supplier of flashlight bodies and components, Brinkmann USA, filed for bankruptcy. These supply issues are complicated by the fact that our RLT Optic, which is the heart of our technology, is a very precise optical instrument, which is currently available from only one source worldwide. While our source is very capable, the precision required to produce it makes high volume serial production time-consuming and difficult. The yields are low and slow. The good news is that by mid-October 2016, Marinebeam will have additional sources developed, which should allow us to keep up with the demand, simplify assembly, and improve production yields.
Where is the Illuminator designed and manufactured?
The Illuminator is not only designed in the USA, but it is also hand assembled here in South Carolina, using components produced in our shop and sourced worldwide. The LED emitters are from Cree USA just up the road in North Carolina. The RLT technology is an American invention with US and worldwide patent protection (Patent #7976204). Dr. Kenneth Li, and Seiji Inatsugu, both American scientists, developed and patented the RLT technology. Dr. Li holds a BSEE from California Institute of Technology. Dr. Li completed his MSEE and PhD in quantum electronics from Northwestern University and University of California, Berkeley respectively. He also completed his EMBA at the University of California, Los Angeles. Dr. Li has held various senior positions in TRW Technology Research Center, PCO, Inc. (Joint venture of Corning and IBM), and Hewlett Packard, where he was responsible for the development and manufacturing of lasers, LEDs, and photodetectors for fiber optic communication. Dr. Inatsugu holds a Ph.D in Physics from the University of Hawaii, and is a specialist in optics and lasers. He had a 26 year career in R&D at Laser Media, Inc. the world's largest laser effects company.
