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 Torcia 365nm flashlight and up to two additional spare 18650 lithium ion batteries.

Battery and Charging Information

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.

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).
