Light Towers

A light tower is a system, not a lamp

A light tower (mobile lighting tower) combines three things: elevated light, its own power source and a stable footing. The telescopic column raises the head to 4–9 m, a generator or battery drives the floodlights off-grid, and outriggers hold it steady in wind. An LED head rated 4 × 150–4 × 350 W, delivering 60,000–160,000 lm, lights 2,000–4,000 m² from one position — far beyond a floodlight on a 1.8 m tripod, which casts a flat beam and leaves trenches in shadow.

Types: generator-driven, battery-powered, balloon

Two things decide: how long the unit must run unattended, and what surrounds the site. A generator-driven tower carries long shifts off-grid; a battery model runs silently and fume-free, so it can work inside warehouses and car parks; a balloon gives soft, diffused light.

The diesel-driven tower in our range is the trailer-mounted Wacker Neuson LTN5Ypa. The compact LED towers from Enar run from the 230 V mains or a generator, and the battery side is covered by 36 V Husqvarna LED lamps on tripods.

Matching a light tower to the site

Start from the illuminance you need. For outdoor work areas, PN-EN 12464-2 sets 20 lx for traffic and storage, 50 lx for ordinary construction work and 100 lx for assembly and inspection.

• Height — trenching and scaffold work call for 8–9 m masts, a single work station for a 2–4 m tripod; raising the head from 4 to 8 m widens the lit circle roughly fourfold.
• Runtime — a diesel tower usually covers 50–150 h on one tank; with batteries, plan spare packs for the rest of the shift.
• Transport — trailer units tow behind a vehicle, cube units load onto a pickup bed; a pneumatic column rises faster than a winched one.
• Auxiliary sockets — some towers carry 230 V outlets for small tools; to power a whole work front, choose a separate 230 V generator.
