Key Takeaways

• Light towers have evolved over centuries from iconic lighthouses to portable generators that provide bright mobile lighting for industries worldwide.
• The main types include engine, battery, solar, and hybrid-powered towers suited for construction, mining, events, etc.
• Key factors to consider are the mast height, lighting power, runtime on fuel/charge, and optional features to meet your job site needs.

What is a Light Tower?

A light tower, also known as a portable or construction light tower, is a versatile mobile lighting solution used across various industries to illuminate large outdoor areas. Powered by diesel engines, these towers contain an array of electric lamps affixed to the top of an extendable vertical mast, which can be either a telescopic pole or an inflatable mast. The mast attaches to a trailer or vehicle, allowing the entire unit to be easily towed between job sites.

Evolution of Light Towers

The need for reliable lighting during nighttime work led to the evolution of light towers over centuries. Before the age of electricity, iconic lighthouses built high on coastlines served as some of the earliest forms of light towers, using fire to create illumination.

In the late 1800s, American cities erected tall “moon towers” powered by oil-fired lamps to light their streets.

As diesel engine and generator technology advanced in the 20th century, portable light towers became critical at construction sites and other outdoor operations requiring bright lighting over large ranges.

Modern Light Tower Design

Today’s light towers come in different models to suit diverse applications. They are equipped with durable features like tires for towing and a generator enclosed in a weather-resistant shell. Various power options include diesel, battery, solar, and hybrid systems.

Modern towers use energy-efficient LED or metal halide bulbs within the mast to provide bright, uniform lighting across a wide area. Their collapsible masts and compact sizes allow for easy movement between job sites.

Vendors offer a range of options for mast height, light power, and generator fuel efficiency to meet the needs of any particular construction, mining, event, or industrial application.

Common Types of Light Towers

Different types of light towers are based on their power source and design. Choosing the right type depends on the needs of the particular application.

Engine-Powered Light Towers

Diesel-powered light towers are popular for construction sites and mining operations requiring reliability and long runtimes. Equipped with efficient diesel engines, these towers can operate continuously for extended periods. Generators powered by the engines provide electricity to illuminate the mast and its array of bright bulbs.

Battery-Powered Light Towers

Battery-powered light towers are ideal for indoor or portable use cases with lower power needs. They have large battery arrays to power the generator and lights without emissions. These towers offer mobility without noise and exhaust but have limited runtime before recharging is needed.

Solar-Powered Light Towers

Combining solar panels with battery storage, these hybrid light towers can operate entirely on clean energy. The solar feature allows batteries to recharge during the day, extending operation into the night. While initial costs are higher, they save fuel expenses over time for off-grid applications.

Portable Lighting Carts

Compact cart-based towers provide portable lighting indoors or for small jobs. Powered by batteries or small generators, they are easily moved between locations without needing to be towed. Their short masts suit confined indoor spaces and easy movement between areas.

Key Features to Consider

When choosing a light tower, some necessary specifications to consider include:

• Mast Height: The mast height directly determines the area of illumination the light tower can cover. Taller masts allow bright lighting across a broader range but may not suit all job sites with height limitations.
• Lighting Power and Coverage: The number and wattage of lights equipped and the type of bulbs, like LED or metal halide, impact the light tower’s brightness levels and coverage width. Higher-powered lights provide intense illumination over large areas.
• Power Source and Runtime: Consider the fuel type, such as diesel, battery storage capacity, or solar panels, and how long the generator can reliably power the lights before refueling or recharging is needed. This affects the duration of operation between maintenance stops.
• Additional Features: Evaluate optional extras such as inflatable or telescopic masts for convenient height adjustment, battery monitoring systems, weatherproof enclosures, and towing hitches/tires for versatile movement between job sites and industries.
