Patented Zoomable Beam
Twist the bezel. The 363Z transitions from a 120° flood — wide enough to light a garage bay — into a focused spot beam that reaches 548 yards (501 meters). One light covers both jobs. No second tool to buy, no second battery to charge.
The zoom mechanism is protected by German Utility Patent DE 20 2019 100 940. This is the original.
3,000 LM-79 Verified Lumens
Independently measured at 3,000 lumens by third-party photometric laboratory under LM-79 protocol. Full report on file.
Output levels: 750 LM (20 hr runtime) / 1,500 LM (8 hr) / 3,000 LM (3 hr) — all on a 5.0 Ah battery.
Universal Battery Compatibility
Cordless freedom on the 4 professional battery platforms that dominate North American jobsites. No proprietary pack. No adapters. No lock-in.
- DeWalt 20V MAX
- Milwaukee M18
- Makita 18V LXT
- Bosch 18V
Also runs on AC adapter (110–120V) for unlimited runtime when a wall outlet is available. Patent-protected UniPower™ contact system auto-detects voltage on every connection.
Pistol-Grip Ergonomics + Any-Job Build
One-handed operation. Trigger-style power control. Balanced for extended use during inspections, tunnel work, and overnight patrols.
Impact-rated housing with weather-resistant seals. Tested to IEC 60068-2-32 free-fall protocol (1.2m, 6 orientations, 5 cycles, no functional loss). Operating temperature: −20°C to +45°C — tough for any work.

Why No IP Number on the 363Z
We don't claim a numeric IP rating for the 363Z because we haven't run that test on this SKU. In the DAYATECH lineup, the 363D is the only light with an independent IP65 certificate — it was built specifically for storm work.
The 363Z is built for a different job: long-range inspection and patrol work. Its housing is weather-resistant and tough for any work, but if the specifying question is "will this keep working in a direct water jet?", the right light is the 363D.
One certificate, one claim. Never both ways.
Best for
- Long-range inspection — tunnels, warehouses, roof lines
- Night patrols and perimeter checks
- Emergency search and rescue
- Outdoor repair at a distance (utility poles, ag equipment)
- Deep-space illumination where a flood won't reach
Skip if
- You need wet-weather certification — see 363D (IP65)
- You need large-area lighting — see 368 tripod (12,000 LM)
- You need a compact flood for close work — see 363B (4,000 LM)
