As to what it can be used for… i’d say you’ll find out once you have one. Lots of unexpected things in fact. For instance it lets you spot a lot of stains you can’t see in you’re house - kitchen and bathroom especially. It can be pretty scary actually. Some minerals and woods do fluoresce and shine under UV light. Of course you can check bank notes to see how sophisticated they can be. It is not a light you use much often but it’s good to have one.
There is a very significant oversight here. If you find a good light, like the D4 or D4S, don’t you want more than one? If I love a light, I try and get it in every color. Recently, I have been loving the PD32 v2. Incredible light at $48 with discount.
Ok, I’ve ordered The Convoy with the installed filter to check if the lady I pay to clean my house is worth the money…… (wonder what she would be thinking if I’d start following her around with the light?)
It’s definitely something new for me so a worthy new addition to my collection.
Btw: over here where I live, it must be about the absolute opposite to a dessert, very few scorpions over here but maybe I can find funny glowing thingies in the water?
I used to use a UV light and injectible UV dye to find very small leaks in air conditioning systems. It was very expensive then, but would find leaks nothing else would. I think they use similar methods for other fluid leaks. It can also identify a murder scene with luminol spray.
you need the new Emisar DT8. everyone needs to try this light! it may look.. wierd. but it looks way better in person, and its performance is Wild! and you can get emitters from nichia e21a 2000k all the way to osram CULPM1 and "everything" in between.
A nice UV option would be the Wurkkos WK30, it has a nice 365um emitter, a very nice 5000K white emitter (samsung LH351D) and a powerful red emitter all in 1 package so it satisfies the need for UV and red.
I recently reviewed it here, I wasn’t sure about it at first, but now I love it.Wurkkos WK30 "on the job" review
