The value you derive from this item compared to other unfiltered UV flashlights, including unfiltered older generation Convoy S2+ flashlights, is that it includes the UV filter that reduces the distracting purple haze you get with most black lights. The fluorescence of your minerals wil pop much better from a distance when the background is not showered in overwhelming purple light. You will locate the minerals that the collectors with inferior 395nm UV flashlights will walk right past. And when you get your minerals home, should you want to sell your new found treasures online, you will have the advantage over others because your photos will attract more bidders to your ad since you wont have the same purple/blue haze on your photos. Differentiate yourself from the crowd with a top quality UV flashlight.

Viewing minerals with this LED Flashlight is a treat! It activates fluorescence in minerals not thought to be LW fluorescent especially due to the UV filter pre-installed. You will get accurate, intense fluorescence from well known longwave fluorescent minerals like Fluorite, Sodalite, Hackmanite. However, you will also see a fluorescent response with many minerals which normally only glow under shortwave UV illumination. Many calcites unexpectedly fluoresce and exhibit phosphorescence under this light. Franklin, NJ Willemite, Calcite and Sphalerite all fluoresce under the 365nm filtered UV of the Convoy S2  365nm Longwave UV LED Mineral Light. There are certainly many fluorescence differences compared to true 254nm shortwave UV light sources. But discovering how some shortwave minerals glow under this light is pretty interesting!


THIS LIGHT is manufactured directly by Convoy for Way Too Cool. Beware of other sellers who are not offering this GENUINE Convoy S2 UV Flashlight. Thank you for shopping with Midnight Minerals for the best in UV Mineral Lights, Lamps, Flashlights! Don't waste your hard-earned money on fakes/copies that don't have a great warranty and great reliability like this UV light. Midnight Minerals has been providing the best lights in the hobby for over a dozen years at this point. And we have been selling UV LED flashlights since about 2010, long before there were many Hunters of Fluorescent Sodalite on the shores of the Great Lakes. And well before anybody named this rock Yooperlites.


Why order an UNFILTERED Convoy from China and wait 30 days? If you haven't noticed lately the price from China has gone up! You won't need to obtain the specialized tool to disassemble the lamp head to install the filter either! In stock here in the Eastern US!!


INTERNATIONAL BUYERS: Please only order this light with ONE 18650 battery or as flashlight-only due to international shippping restrictions. 


NOTE: Mineral specimens in photo are for illustrative purposes only and are not included with this flashlight. 



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.


Except for the LED itself, there is a standard 1 year warranty for the main components of the flashlight. Burned out LEDs are covered for a three-month warranty. If you burn out the LED after three months, you can ship the head of the flashlight to Way Too Cool at your expense, and for a fee of $18.00, WTC will replace the LED and ship the head back to you.
