Light towers are often required to operate 24/7 to help operators deliver jobs on time, so preventing downtime is crucial. Choosing a light tower with extensive maintenance intervals, for example, after 600 hours of operation, will help minimize downtime. Having easy access to the light tower’s maintenance points can also help speed up troubleshooting and the overall maintenance process, reducing downtime. Some light towers from leading manufacturers, like the HiLight H6+ light tower from Atlas Copco, feature a single pop-up canopy that is easy to fit and remove, providing 360º access to the unit for internal maintenance. This makes them quick and straightforward to service in only 40 minutes.

As many light towers are used in very harsh weather conditions, the design of the canopy can be a game-changer when it comes to optimizing performance and usability. It is vital that the body of the light tower is made of material that is corrosion and crack resistant, environmentally friendly, and able to meet the demands of the working environment. For example, Atlas Copco’s HardHat® canopy is made of medium-density polyethylene, rather than metal, to protect the tower from the elements. What is more, in a model like the Highlight H6+ from Atlas Copco, HardHat® is also used for the body of the light tower, ensuring the performance and appearance lasts throughout years of service. The innovative design and tough material help ensure that the tower continues to perform throughout years of service, helping retain a high resale value and providing an outstanding total cost of ownership (TCO).
While a light tower is used to create a safe environment for workers and the public, it is also a piece of equipment with safety risks of its own. It can topple over due to uneven ground or high winds or strike an object above it when raising the mast. Therefore, to minimize risks, it is important to select a light tower with an advanced safety system – ideally one that goes beyond the mandatory requirements.
Atlas Copco’s SmartMast safety system detects a range of potential risks, including high winds and obstacles that are between 300 and 500 mm (11.8 and 19.7 in) above the light tower. It also identifies if the surface is not stable enough to support the tower and retracts the mast to a safe height if it receives an impact. This feature prevents the light tower from becoming unstable, reducing the risk of it blowing over.
The mobile solar light tower, known for its ease of use, portability, and extensive illumination capabilities, has become a staple in various settings. This includes emergency disaster relief, major events, cultural performances, and maintenance work in water management projects. Its adaptability to diverse terrains, including earthquake-stricken areas, and its resilience in severe weather conditions like storms and heavy rain, make it indispensable for firefighting tenders, water conservation, hydroelectric projects, and emergency flood response operations. Moreover, it proves invaluable at construction sites during nighttime. Furthermore, the application of mobile lighting has expanded into the commercial sector, providing illumination for outdoor parking lots and event spaces.
However, how does one choose a mobile solar light tower? Please find some key points as follows:
1. LED Lights and Power Consumption
To achieve the same output illumination, LED lights consume less power compared to MH lights and have a longer lifetime than other traditional lights.
LED floodlights and LED projector lights are good choices for mobile light tower trailers.
The light efficiency of 140lm/w-180lm/w is common for outdoor LED floodlights in the market, with most around 160lm/W, as is the case with Biglux's LED lights.
The first step is to check the light output illumination you need, then confirm the power consumption of the light.
For example, if 90,000lm is required, then you can choose 4*150W LED lights.

Some projects have specific requirements for light illuminance; you can provide us with the lighting area and related information, and we can create a Dialux simulation to determine the LED light wattage you need, the installation height, and figure out the place of deployment. (For more details, please let me know, and we can discuss it together.)
2. The Height of the Mast
Mobile light towers are installed with a telescopic mast, and usually, there are some limitations on the mast height, with different suppliers offering different choices. Generally speaking, based on experience, if the wattage is 600W or less, a 7-meter mast is sufficient. For higher wattage lights, Biglux offers 9-meter and 12-meter versions.
3. Working Frequency and Hours per Day
Some applications require 10-12 hours of lighting time per day, 5 days a week, for example.
4. The Solar System to Support the Lights
The solar panel wattage and battery capacity you choose depend on your local sunshine conditions and the required electricity power each day.
For example, in most areas of Qatar, each 1KW solar panel can generate approximately 5KWH of power per day on a yearly average.
To support a 600W LED light tower working 10 hours, around 6KWh of power per day is required; at least a solar trailer with 3*435W solar panels + an over 95% MPPT controller should be considered.
If the light towers need to work every day, it's better to have higher wattage PV and larger capacity batteries, in case of rainy or cloudy days.
Additionally, a backup generator or AC charger should be considered.
