Product Manuals

FIELD APPLICATIONS

FROM ENGINE BAY TO CAMPSITE.

Tracing wiring under a hood, walking a trail after dark, or setting up camp: the SZ3 puts light right where your hands are working.

Engine Bay & Garage Work

Stick it to the hood or a steel panel with the magnetic tailcap, tilt the head down, and see wire colors clearly with high-CRI light. Both hands stay free.

First Responders & Roadside Crews

Clip it to a jacket or vest and tilt the head down to read paperwork, inspect a vehicle, or work a roadside scene. Signal modes are one double-click away.

Trail & Night Hiking

Clip it to a cap brim for hands-free light on the trail. Use the spotlight for distance (up to 140 m in Turbo) and flood for nearby footing.

Campsite & Night Reading

Stand it upright on a picnic table and use the flood on Low for reading or cooking (7-hour runtime). The 10-mode side light adds a soft glow to camp.

TRUE COLOR RENDERING

TELL WIRE COLORS APART

CRI 90+ light helps you tell similar wire colors apart and read surface detail, so you can trace and inspect with confidence.
Typical CRI 70 light
SZ3 (CRI 90+)

DUAL-BEAM SYSTEM

SPOT FOR DISTANCE. FLOOD FOR DETAIL.

Switch between a focused spotlight and a wide flood with a double-click. Add the 0–100° swivel head and magnetic tailcap, and the light stays where you aim it, hands-free.

The flood beam spreads soft, even light across your work area for close-up inspections, wiring, and benchwork. Output runs from 10 to 500 lumens.

The spotlight's focused optic throws a tight, long beam: 130 m on its own, 140 m with both beams in Turbo. Use it to read a trail, check a fence line, or spot a landmark across a job site.

BUILT FOR THE JOB

BUILT FOR THE SHOP, THE ROAD, AND THE TRAIL.

The SZ3 is a flat, pocketable work light made for technicians, tradespeople, and everyday carry. It has an aerospace-grade aluminum body with a Type III hard-anodized finish, IPX6 water-jet sealing, and 1 m drop testing, so it's ready for daily use in the shop and in the field.

FAQ

Q1: What does CRI 90+ mean, and why does it matter for inspection work?

CRI measures how accurately a light shows colors. With CRI 90+ light, the SZ3 helps you tell similar wire colors and surface details apart during inspections and repairs.

Q2: How long does the battery last?

The built-in 1,500mAh battery runs up to 52 hours on floodlight Moonlight and 7 hours on floodlight Low. Spotlight High lasts 65 minutes and Turbo 55 minutes. It recharges over USB-C.

Q3: How do the spotlight and floodlight work? Can both be used at the same time?

A: The SZ3 has two independent optics:

  • Spotlight: a focused beam that reaches up to 130 m (4,225 cd) on High, for distance.
  • Floodlight: a wide, even beam up to 500 lumens, for close-up work.
  • Switching: double-click the main button while the light is on.
  • Both together: double-click from off for Turbo, which runs both beams at 1,300 lumens and reaches up to 140 m.

Q4: Is the swivel head durable, and how can I use it hands-free?

The 0–100° swivel head adjusts smoothly and holds its position. The magnetic tailcap sticks to steel surfaces like hoods and tool chests, and the two-way stainless steel clip fits a pocket, vest, or cap brim.

Q5: What is the side light used for?

A: The side light strip has three jobs:

  • Hazard beacons (3 modes): double-click the side button from off for a slow red flash, red/blue strobe, or SOS. Red/blue is for hand-held signaling only. Check local regulations.
  • Ambient effects (10 effects): press and hold the side button from off for a soft glow at camp, in a tent, or on a nightstand.
  • Battery indicator: the strip shows approximate charge by color and length.

Q6: Does the SZ3 get hot during use, and how does thermal protection work?

A: The head can get warm at high output, especially in Turbo. A head-to-body thermal isolation design helps keep the body comfortable to hold. Built-in temperature sensors monitor the head and step output down when heat rises [Turbo steps down after about ___ minutes].

Q7: Can the SZ3 be used while charging?

A: Yes. When connected to a USB-C power source or power bank, Moonlight, Low, and Medium modes work on both the spotlight and floodlight. Higher modes are not available while charging. That makes it usable as a steady work light during long jobs or power outages.

Q8: Is the SZ3 waterproof?

A: It is IPX6-rated, which means it is protected against powerful water jets from any direction. It is not designed for submersion. Keep the USB-C port cover closed.
