Portable handheld blacklight reviews
- Chauvet 6” Handheld Blacklight
This Chauvet handheld blacklight is 6x5x2 inches and weighs 3lbs. It requires 4 size AA batteries, which is not included with the product.
Very reasonably priced, it also offers good quality and works well for a long period of time. Unlike some other LED UV light devices, the Chauvet offers users a classic bulb design which functions well with all types of fluorescent substrate.
The downside of this product is a small LED backlight on one end, which burns out all too soon. But this is only one little optional addition, so cannot be considered a major fault as such.

This product is most useful to locate pests around the house and also for gem and mineral detection.
Since this is very light, it effortlessly doubles up as a portable forensic product, helping security and law enforcement officers.
This handheld blacklight is only about three and half inches long and needs 3 AAA batteries.
Many users, though, have been rather dissatisfied with this product. While some feel that it can fluoresce only reflective white items, others feel that it highlights only some spots on the material, rather than the entire surface.
