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.
