ESCO LITE UV Blacklight Flashlight, 100 LED, Black, 395 nM, battery powered

With 100 LEDs set at 395 nm, this UV blacklight flashlight gives a wide spread of UV-A light, and its aluminum body measures 19 x 3.5 x 7.6 cm. The handheld light weighs 236 g and takes 3 AA alkaline batteries, which are not supplied. The brand lists it for checking fabrics and surfaces, for UV resin work and for outdoor scorpion spotting.

What the box holds and what it does not

• The ESCO LITE light itself, in black, model ESCO_0060.
• A wrist strap, so the light can hang from the hand while you work.
• No batteries: three AA alkaline cells are needed before the first use.

Is this blacklight right for the surface you want to check?

The brand limits this unit to dry stains, so wet patches are outside what it is meant for. Results come in dark conditions, and a dim room gives a cleaner contrast than daylight. Three AA alkaline batteries are required and none come in the box, so the light is unusable until you fit them. The body is 19 cm long and 3.5 cm wide, with a 236 g weight in hand. Some jobs sit outside a UV light altogether, since the brand does not list it for liquids or for surfaces it has not named.

100 LEDs at 395 nm, a metal body and the jobs the brand lists

Each of the 100 LEDs emits at 395 nm, which is the long-wave end of the UV range, so the beam is spread across a wide head rather than a narrow spot. The aluminum body dissipates heat from the LEDs. The light is handheld and built to be carried, and the strap keeps it attached to the wrist.

The brand lists several uses. Fabrics and surfaces can be checked for fluorescent materials, and the same light works for bed bug inspection. It can also be used for UV resin work, reveal minerals and rocks, show fluorescent shells and corals, and help spot scorpions outdoors. For stain checks on fabric, the light works on dry stains only and gives its best results in the dark.

Three AA batteries and the aluminum housing

Power comes from 3 AA alkaline batteries, which the brand notes are not included, so the light stays off until cells are fitted. The aluminum housing is the material behind the heat dissipation, and it also shapes the 19 x 3.5 x 7.6 cm body that holds the 100-LED head.
