Product Description

Due to the fact that the high pre-holiday demand for this product is currently outpacing our production capacity, delivery leadtime for the Long Range Illuminator orders is approximately 3-4 weeks.  Additionally, until we can catch up, we are limiting the flashlight orders to one per customer.  This is to ensure that every customer has access to at least one.   Please take that into consideration when ordering.  These flashlights are well worth the wait.


This is the same lamp recently reviewed and recommended in Sail Magazine, , National Fisherman Magazine, the January 2015 issue of Boating Magazine, Steve Dashew's SetSail Tech Blog, and the French sailing magazine Voiles & Voiliers .

While this looks like an ordinary LED flashlight, it is really Marinebeam's new and patented Ultra Long Range LED Illuminator Spotlight, which has an ANSI-FL1 rated usable range distance of over 650 meters, which is longer than any other handheld LED device in this category, period.

This ultra-collimated beam illuminator is made specifically as a handheld searchlight for spotting bouys, channel markers, crab pots, etc, at night. It is also useful for search and rescue, 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 and unreliable batteries -just 3 standard D-cells.  If you have used portable Q-beam™ type spotlights on-board, you know that to use one effectively you have to send someone up to the bow to deploy it. They really aren't practical to quickly use from the cockpit, because all of the spillover light is reflected back into your eyes and destroys your night vision.  We love this light because its beam is super collimated, and has no spillover light, so it is easily and quickly deployed from the cockpit, and doesn't reflect back and ruin your night vision.

It uses a remarkable patented invention called Recycled Light Technology, which is a simple, cost-effective way to dramatically increase the brightness and efficiency of standard LEDs. It uses a passive component technology that increases the useable light output of its Cree LED by over 2.5 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 candlela compounding is only possible with RLT. 

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 (illuminance or lux) is off the charts. So, DO NOT just use our lumen figures to understand this lamp's output or its long range illumination capabilities. As a point of reference, a normal LED flashlight would need more than 2,800 lumens to get the same ANSI beam distance, and would have nearly 50° of wasted spill over light. This 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.

For a further detailed explanation of how this light beats all other LED flashlights, read our How RLT Works document

The best analogy to understand this concept 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 650 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 still produce 0.25 lux of illuminance.   So, that is the equivalent light, at 670 meters, of a full moon in an open field on a clear night.  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 a 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 to12 hours with the standard batteries.  That is possible with this Illuminator.

The Marinebeam Ultra Long Range LED Illuminator is tough and impact-resistant, with a lightweight aluminum casing resisting rust and corrosion. It also features a long lasting Cree XML2 LED made by Cree USA, a world leader in LED technology.
