Illuminator RLT Handheld Long-Range LED Spotlight

What is it? It is a flashlight body that behaves like a long-range spotlight, having a FL1 rated beam distance of 690M.  That doesn't mean that you can see the beam from 690M away, but rather that it fully illuminates the target 690M away (which is the FL1 standard).  You (and Search and Rescue) can see the beam easily from 20 miles or more (depending on height of eye).
Is it a general purpose flashlight?   No.  It is specifically designed for spotting crab pots, channel markers, buoys, and crew overboard (MOB) at night --at significantly more range (and with a much tighter beam) than you ever thought possible with a handheld "flashlight".  The beam has almost no spillover light, so it doesn't reflect off of the boat's fiberglass surfaces and ruin your night vision.  Thus, you can spot buoys from the cockpit rather than the bow. Oh, and it can run up to 12 hours on full power a set of off the shelf D-Cell batteries. How does it do it? It uses RLT, which is Recycled Light Technology, a patented invention originally developed by the scientist Dr. Ken Li to double the efficiency of lasers coupled to fiber-optics for data transmission.  How does a layman understand that it is not just some sort of gimmick? Well, if you think about what you need for a spotlight to reach long distances, it isn't raw Lumens, it is Lumen density (Candela).  In other words. you need to somehow get those raw lumens down-range in an extremely tight spot.  Unfortunately, normal flashlights are not capable of doing this thanks to the physical limit of the law of Etendue.   
Imagine a million lumens on one side of a fence, with a 2" hole in the middle of that fence.  A layman can understand that only a small portion of those million lumens on the one side of the fence can pass through that hole in the fence, and that most of those lumens are wasted because they are blocked by the fence.  This analogy represents the same problem that a spotlight has.   In the standard spotlight or flashlight you have a light source (LED) with X amount of lumens, and then you have a very small aperture (lens).  Even if you use a reflector to gather the light and try to redirect it out of the aperture, most of the flashlight beam is still wasted in a divergent beam.  You can see this in a normal reflector spotlight when you point the beam against a wall.  There are always two beams.  One is a super bright spot of collimated light (good), and the other is the big concentric halo of dimmer diverging light.  This divergent beam is spreading out rapidly and heading off into space.  So, your target down range will never see that light.  So, regardless of the initial lumens (and power used by the batteries), most of the light in a reflector spotlight is wasted --at least if we wanted that light to be used to illuminate a distant object. Ok, so how does RLT work? It simply reflects the wide angle light right at the emitter source and redirects it directly back to the LED.  This light re-excites the LED phosphor thus recycling the light, which is then released out to the lens in a 30 degree solid angle (cone), which matches the size of a collimating lens in the aperture.  Thus, all of the recycled light now reaching the lens is also coming from the lens' focal point (the LED itself).  So the wasted light is captured, and is perfectly collimated leaving the lens. So, can't I do the same thing with a boatload of lumens? Yep, but remember that lumens are nothing but Watts that your eye can see.  Every Watt has to come from somewhere (the batteries), and each Watt makes 3.4 BTUs of heat, and heat is the singular enemy of LEDs.  This is why high-output flashlights have bright, but brief, turbo mode button.  When looking for a long-range light, it is Candela that you are looking for.  Lumens really mean nothing unless you can get those lumens out through the front of the flashlight.  You would need approximately 3,000 lumens to equal the range of the Illuminator RLT. Summary So, the RLT is nothing but a super-efficient way to use all of the available lumens and collimate them for down-range illumination.  The result is a low-power, high-output compact spotlight that you can run for up to 12-hours straight.
