This High Performing LED flashlight is custom made for Way Too Cool, LLC by the same factory that makes the other Convoy S2+ UV flashlights. Because of my patent, the manufacturer has agreed that I am the exclusive distributor of this product in the USA.
This flashlight is available in two versions: a 6-watt (grey body) version and a 3 watt (black body) version. Both lights use a high quality LG ultraviolet 365nm LED (LEUVA33U70RL00). They are a favorite among fluorescent gem, rock and mineral collectors for their portable size and excellent UV output.
The S2+ 4-watt (black body) is is driven with forward current of 1050 mA, so the wattage is about 3.8-4, and the radiant flux is approximately 2W. The other 1.8 watts of energy is dissipated as heat.
The S2+ 6-watt (gray body) is driven with forward current of 1750 mA, so the wattage is about 6, and the radiant flux is approximately 3W. The other 3 watts of energy is dissipated as heat. This is approximately THREE TIMES the amount of UV as the original Convoy S2+ flashlight that had the Nichia LED. This LED is not only stronger, but more efficient.

Built to Waterproof Standard IP-65, the unit is safe from accidental water immersion, the Ergonomic Knurling Pattern offers a comfortable, secure grip, and the reflector emits excellent beam shape. The flashlight has an ON/OFF Click switch in the tail cap, and it has a Lanyard. The power supply is one 18650 lithium-ion battery (protected or unprotected). Dimensions: 4 5/8" long x 15/16" diameter. Weight is about 81g w/o the battery.
The reflector focuses the UV output to an intense, but smooth "spot" with a range of 10 meters or more for finding specimens up close or quite far away. The intensity of the beam is strong enough to cause fluorescence in materials that do not fluoresce very well under the normal UV A tubes used in standard UV lamp fixtures.
A holster can be purchased as an accessory. The holster can hold the Torcia 365nm flashlight and up to two additional spare 18650 lithium ion batteries.
Using a single 18650 Li-ION battery rated from 2,500 - 3,000 mAh, the flashlight provides up to an hour of use on a charge. The batteries will arrive discharged because of postal regulations and the batteries should be charged prior to use. Please be aware that some manufacturers claim that their 18650 batteries are rated for up to 9,000 mAh and that any value over 3,500 mAh should be carefully investigated for accuracy.
The flashlight set comes with two 2,500 - 3,000 mAh Rechargeable Li-ION batteries and a simple-to-use Li-ION smart charger. The charger provides a safe charging rate of around 300 mA. The charger has fold away US style prongs, but it will operate on 100-240 volts AC and 43-63 hertz. It will take an hour or two to top off the battery after occasional use. If mostly discharged, the battery will need to charge for up to 12 hours. While the battery is charging the LED will be red. When the battery is fully charged, the LED turns a solid green and the battery should be removed from the charger.
The Convoy S2+ lights feature outstanding output, even during prolonged runtime. We conducted a comparison of the original Convoy light, our 4-watt S2+, and our 6-watt S2+. Each light was positioned such that the beam would shine into a tank full of tonic water. This helps to illustrate the distance of the beam. Interval photos were taken for a period of 30 minutes, during which time the lights ran continuously. As you can see from the photos, output from the 6-watt S2+ remains impressive, even after 30 minutes of runtime (not recommended).
William Gardner has US Patent #7781751 for the use of colored glass absorption filters (and other kinds of wavelength changing absorption filters for use with UV LED battery operated devices). If someone imports, makes, uses, offers to sell, or sells filtered UV LED flashlights in the U.S., using colored glass absorption filters such as Hoya glass, Kokomo glass, or ZWB2 glass, they are infringing US Patent #7781751. William Gardner has authorized Way Too Cool, LLC to use his patent and he is willing to license the use of the patent to other manufacturers of filtered UV LED Flashlights and similar UV battery operated devices. If you buy a filtered UV flashlight or other similar battery operated product that does NOT have U.S. Patent number 7781751 on it - please be aware that it is COUNTERFEIT and that selling it, or purchasing it, infringes on the patent and is illegal.
United States Code: Infringement of Patents, 35 U.S.C. § 271-272

(b) Whoever actively induces infringement of a patent shall be liable as an infringer.
(c) Whoever offers to sell or sells within the United States or imports into the United States a component of a patented machine, manufacture, combination, or composition, or a material or apparatus for use in practicing a patented process, constituting a material part of the invention, knowing the same to be especially made or especially adapted for use in an infringement of such patent, and not a staple article or commodity of commerce suitable for substantial non-infringing use, shall be liable as a contributory infringer.
