Key Features

UV LED Technology (395–410nm): Emits intense black light that causes fluorescent materials — including pet urine, certain stains, and scorpion exoskeletons — to glow visibly in dark conditions.
Adjustable Zoom Focus: Slide the head forward or back to zoom in on specific spots or widen the beam for broader area coverage — up to 50–100 metres lighting distance.
Durable Aluminum Alloy Body: The shock-resistant, hard-anodized aluminum shell is built to withstand everyday use and light impacts, keeping the torch protected.
Waterproof (IPX-4 Rated): Splash-resistant construction makes this torch suitable for outdoor use — camping, hiking, fishing, and night-time inspections in variable weather.
Compact & Portable: Measuring just 92 × 25 × 25 mm and featuring a tail push-button switch with a lanyard hole, this light is easy to carry in a pocket or pack.
Multiple Dimmer Settings: Supports 2–4 brightness files, giving you control over output intensity to suit the task at hand.
XPE + COB LED Beads: Dual-bead setup provides a hard, penetrating UV beam ideal for detail inspection work.

Frequently Asked Questions

Q: What wavelength does this UV black light flashlight emit?

A: This UV flashlight operates at a wavelength of 395–410nm, placing it firmly in the near-UV/black light spectrum. This range is highly effective at causing fluorescent materials — such as pet urine residue, certain inks, and scorpion exoskeletons — to visibly glow when viewed in a darkened environment.

Q: Does the UV flashlight come with a battery?

A: No, the battery is not included. The flashlight accepts one 3.7V 14500 rechargeable lithium battery or a standard AA battery, both of which are widely available. Be sure to purchase a compatible battery separately before use.

Q: Is this flashlight suitable for outdoor use?

A: Yes. The SK68 carries an IPX-4 waterproof rating, meaning it is splash-resistant and well-suited for outdoor activities such as camping, hiking, and night fishing in light rain or wet conditions. The shock-resistant aluminum body adds further durability for field use.

Q: How do I adjust the focus on this UV flashlight?

A: Simply slide the front head of the flashlight forward or backward to zoom the beam in for a tight, focused spot or out for a wider area of illumination. The adjustable focal length lets you target specific stains or survey broader surfaces with ease.
