5V 3W USB Powered 395nm UV Flashlight Torch Ultra Violet LED for UV Glue Curing, Pet Urine Stain Detector, Resin Cure 3D Print Cellphone Repair Tool

Tiene muy buena potencia, cura bien la mascara uv, la recomiendo.

This is a bicycle headlight with an ultraviolet chip. The illumination pattern is that for street riding. The central spot is bright and large and useful.

My first adventure into using UV cured glue required a UV light and this works fine for that. There are things about it that are 'odd' but do not detract seriously from how it works. The housing appears to have been intended to attach to a round bar (handlebar?), in fact the light comes with two heavy rubber bands to use it in that manner. I don't foresee using it as a bicycle light and haven't thought of anything to mount it on, it is a little awkward to hold. The cord (about 3') has been long enough but another foot would have been handy for my use. I guess that the only thing that I don't like is having to go through the progression of it being ON HIGH, then ON LOW, then ON STROBE before getting back to OFF every time I use it. Not all that handy when holding onto the stuff that you are trying to glue. So, it works fine for my needs, I may yet get a battery powered UV light just to do away with the need for a cord and to get a simple ON-OFF mode but I chose this at least in part so as to NOT have something that looked like a 'normal' flashlight, figuring my wife would grab it out of the drawer and then stare into it when it didn't work as she expected and this light is fine for that!

I purchased this to use with a windshield repair kit, which required UV light to harden the repair material. The kit was able to make use of sunlight exposure as a UV source, but I wanted to work in a warm garage and not have to wait for a sunny day. The light worked very well for this purpose. I used my USB volt/ammeter to check the current draw and found 5V/1.5A on high power (7.5W) and 5V/0.5A on low power (2.5W), which is close to the stated specifications. It's also quite interesting and fun to plug this into a small battery pack and walk around looking at things around the house under the "black light." :-)

...and 0.7 watts on low. This is power input, not output.Other than running at well below rated power, it is a pretty neat package. I had been thinking of converting an old Magicshine bike light to uv, and adding a usb cable so that I could find a use for my usb power bank. Low and behold these guys have done just that! It even has the handlebar mount.The optics are too focussed for my needs, but I can modify that.If you need a stand for this light, you can use a microphone stand and a short piece of 3/4" pvc tubing. Clip the tubing into the mic stand, and use the handlebar mount to attach the light to the pvc. This trick also works for most flashlights, but without the pvc.

I use in my fly tying as the light remains consistent due to not using batteries. It runs runs off USB plug on front of my computer. I have several other UV lights but this is far and away the best of the bunch.

This is the best UV light I have found. No batteries to go bad. Its always ready to use. I find myself using the strobe setting more than the other two settings. Setting one is STRONG!!! It will make smoke. One downfall, you will need a USB power spot (not provided) to plug in the provided cord. Mine didn't come with one.

I bought it to cure UV resin on pens. It is not really strong enough to completely cure quickly. It semi cures and I finish in the sun.
