Convoy C8 Shortwave UV LED Flashlight

Harness the incredible power of shortwave UV with this custom flashlight! The Convoy manufacturer has created a filtered UV flashlight specifically for Way Too Cool (WTC) using the Convoy C8 host.

  • 1-3/4" inch head with 39mm ZWB2 glass filter pre-installed
  • Increased 100 milliwatt output via boost driver
  • Waterproof standard IP-65 protects the unit from accidental water immersion
  • Ergonomic knurling pattern offers a comfortable yet secure grip
  • Polished reflector emits excellent beam shape

Product Specifications

  • ON/OFF Click switch in tail cap
  • Battery one standard 18650 lithium-ion battery (protected)
  • Output - 100 milliwatts
  • Dimensions 5.5" long x 15/16" diameter (body)
  • Weight approximately 180g


This is a high-performance light and is not intended for continuous use because the LED WILL overheat and burn out if the light is left on continuously for too long. The flashlight sheds the excess heat to the surrounding air - so if it is cold out - say less than 55 degrees F, the flashlight may be operated for much longer periods of time than if the surroundings are room temperature. When the head of the flashlight feels hot to the touch, turn the flashlight off and let it cool for a few minutes. Just turn it on when looking, off when not. Don't make the mistake of putting it in your pocket when it is turned on.


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.
Convoy C8 + UV has several important differences from a standard Convoy C8 white light. It is custom-manufactured by Convoy exclusively for sale in the USA by William Gardner/Way Too Cool, LLC, and WTC dealers. This flashlight includes a ZWB2 filter glass pre-installed. It uses a high quality ultraviolet LED, the same one found in the Convoy S2+ UV Flashlights.

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 protected 18650 lithium-ion battery, or two batteries with the optional extension tube.

Testing shows that the C8 light is slightly more powerful than the Convoy 6/3 offered by Way Too Cool Dealers. This new flsahlight appears to be brighter than the 6 watt Convoy S2+ UV flashlight because the reflector is larger and is shaped differently (and there is a larger filter glass). It is able to fluoresce a sample of Greenland fluorescent sodalite at a distance of approximately 80 feet. The light has a 1-3/4" diameter head and a polished reflector that focuses the UV output to an intense, but smooth "spot" with a range of 80 feet 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.  

Battery and Charging Information

Some of the WTC Dealers offer different options for the batteries and the charger. When purchased directly from WTC, the flashlight set comes with one protected rechargeable Li-ION battery, the filter pre-installed and a charger for 1 battery.

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.
