Product Description
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.
You can read more about the Convoy lights in this article.
NOTE: Due to rising costs, each light ordered will include ONE 18650 rechargeable battery instead of two, effective January 2022. Additional batteries can be purchased for a small additional cost. Thank you for your understanding.
SAFETY WARNING
The LED is a Class 3B LED hazard. Do NOT look directly into the beam of the flashlight and do not point it towards any eyes.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 flashlight and up to two additional spare 18650 lithium ion batteries (sold separately).
Battery and Charging Information
Using a single 18650 Li-ION battery rated from 2,500 - 3,000 mA, the flashlight provides up to an hour of use on a charge. The battery will arrive discharged because of postal regulations and the battery should be charged prior to use. Please be aware that some manufacturers claim that their 18650 batteries are rated for up to 9,000 mA and that any value over 3,500 mA should be carefully investigated for accuracy.
The flashlight set comes with ONE 2,500 - 3,000 mA Rechargeable Li-ION battery 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.
Runtime and Output
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).
Seeing is believing!

Patent Information
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.
