Handy UV / blacklight flashlight which can give light at 2 frequencies due to the 2 built-in LEDs. This combination ensures that the flashlight can be used widely and illuminates much more than just 395 Nm.
What is the advantage of 365Nm? Less visible light and greater contrast. Especially a color such as red lights up much nicer, but other colors also give a better contrast.
What is the advantage of 395Nm? With less wattage a high UV effect. Colors like green glow brighter but with a purple glow.
The flashlight works on 3 AAA batteries but can also operate on a 18650 rechargeable battery. (Both not included).
By pressing the button you turn the lamp on and off. Press it gently to switch between the different positions, like only 395 or only 365 or both activated.
Our opinion: Very useful and affordable UV flashlight and it will certainly appeal to people who research minerals or painting restoration for research. But this flashlight can also make a difference for hygiene research. It is powerful enough for most users and easy to carry thanks to its modest dimensions. We cannot find any disadvantages.
