    They are bright, and they shine ok, but not in UV. I used them to check bank notes, and they didn't show any UV mark. The color is very similar, but not real UV Read more

    -Bright; -Cheap; -Work voltage 3,2-3,4 V (can be easily used with 3,3v batteries); -Standard (20mA) max current consumption. UV lenght (as all cheap UV emitters) has wavelenght near 410nm. UVA range has 315—400 nm. So it has much more visible blue spectrum. UV wavelength didn't shows any watermarks on ... Read more

    They are really cheap and all of them work perfect. All have same intensity and and brightness. Good build quality. Could be brighter, and packaging could be better, but none of them are broken so no problem this time. When voltage is not enough they can turn bluish. The specs are not published, so no ...

    They are cheap They work well The luminosity looks constant accross all LEDs They were all alive They could be brighter. I have a UV flashlight I got from somewhere else years ago and the UV LEDs in it are noticably brighter than these LEDs. If you were going to use these for a flashlight or room lighting,...

    -They all come OK -Cheap -Bright -They work as expected -Can be adapted to use as flashlight The light is not UV at all, but it's okey for the price. Remember to use and appropiate source for connecting this led. If you are using a voltage source of 2.3 V or more, i recommend you to use a resistance.... Read more

    - They look professional (as oppose to cheap) - Good value for money - Suitable for smaller applications - Packaging was sufficient (bubble plast wrap), no leds bent here - There is a distinct purple hue that these leds give off. I think this is normal for most cheap UV leds. The lighting is probably ... Read more

    Cheap and functional. Somewhat irregular lighting pattern, so some trial and error is required to make an array which covers a larger area with UV light without dark spots. I used 40 of these to make a UV exposure box for PCBs. Works like a charm, but you'll need to be very careful to make sure you get ... Read more
