#Best uv black light flashlight series
And yes, they work just fine! They will fit the Convoy S series well. I chose 2 sizes: 19.5 x 2mm thickness and 20.5 x 2mm thickness. Actually, I bought mine for $0.47 and $0.46 respectively. A couple of years ago, these zwb2 filters were very expensive, but nowadays you can get them for less than a dollar. Cheaper UV LEDs tend to produce quite a bit of unwanted, unnecessary visible light. Ultraviolet light can be used to find unknown substances, but as you can see, the differences between the different UV lights are large and obvious.ĥ: Test filters for UV flashlights: ZWB2 Improve your UV flashlight and block visible light with a ZWB2 filterĪ zwb2 filter looks like a black piece of glass, but in reality, it is used to block out any visible light a UV LED may produce. The SK68 was simply too weak with the used camera settings. In this kind of environment, the winners are clear. I presumably used the lower mode in this picture. Only after I performed this test, I noticed that the Jaxman U1C has actually 2 modes. Jetbeam Jet UV Mantaray S1 Ultrafire SK68UV Convoy S2+ Convoy S2 Jaxman U1 Jaxman U1C Sofirn SF32UV Weltool M2BF Xanes 51UV Convoy C8 UV Again, the weaker lights don’t look very good in the pictures. I used the following settings on my camera: ISO1600, F5, 1/3 sec. So… I walked around in the dark, searching for a spot with an unknown substance… and I found it…. And again, after 7 days of waiting, it was impossible to notice cooking oil on the carpet I used for testing. He also recommended testing with cooking oil. Then, the owner of Weltool recommended testing Radiator Coolant, but after 7 days of waiting, the coolant wasn’t visible with any light I tested. But even without using UV light, these spots were visible, so kind of useless to use UV. The main difference is in the minute details, and the width of the beam.ģ: Find unknown substances with UV Black Lightįor this test, I wanted to see if I could observe dried blood on clothes. Lastly: every half-decent UV flashlight is able to show watermarks.The Convoy C8 has a deep reflector and the beam is more ‘throwy’ (meaning: it’s meant for long-distance use) and therefore, not recommended for close-up work like checking bills. Mantaray S1 has a lot of visible light and makes it hard to see the bills.The beam looks purple instead of a deep blue/purple. The Xanes 51UV uses a 395nm LED, but may actually be above 400nm.The 365 nm is deeper into the UV spectrum and has less visible light.īasically, 365nm is preferred over 395 for most applications where UV is needed.
UV flashlights are often referred to as 365nm or 395nm. UV light should be invisible to our eyes, because of the wavelength. Jetbeam Jet UV MantaRay S1 Ultrafire SK68UV Convoy S2+ Convoy S2 Jaxman U1 Jaxman U1C Sofirn SF32UV Weltool M2BF Xanes 51UV Convoy C8 UV Jetbeam and Ultrafire flashlights are much weaker than the competitors so I had to use the auto shutter speed function on my camera. I set the camera to ISO1600, F4, but with automatic shutter speed. Because it’s illegal to own any counterfeit bills or money, I can only show authentic money. These ‘hidden’ characteristics only appear under the proper wavelength of UV light. Now, I will check which flashlight shows the ink used in these bills. You can compare the LED with the one of the Convoy S2 (which is an LG UV LED). The LG UV LED in Sofirn’s flashlight, looks more like a Nichia 365UV (like the one in the Convoy S2+).Unfortunately, I couldn’t take a picture of the UV LED of the Weltool M2BF, because the bezel is glued.Jetbeam Jet UV Jetbeam Jet UV MantaRay S1 MantaRay S1 Ultrafire SK68UV Ultrafire SK68UV Convoy S2+ Convoy S2+ Convoy S2 Convoy S2 Jaxman U1 Jaxman U1 Jaxman U1C Jaxman U1C Sofirn SF32UV Sofirn SF32UV Weltool M2BF Xanes 51UV Xanes 51UV Convoy C8 UV Convoy C8 UV
