If you are planning to purchase a mobile light tower suitable for your application, keep following several key considerations in mind:
Lighting capacity: Consider the lighting capacity first. Determine the amount of lighting you will need according to the size and location of the job site.
Fuel type: Each fuel type light tower (diesel, gasoline, and solar, etc.) has its own pros and cons. For example, opt for diesel light towers or hybrid light towers with generators for high-intensity need, especially in remote areas lacking grid access.
Height adjustment: Max adjustable height of a light tower also determines the size of illuminance coverage. So choose the height of the light tower based on the requirements of your job site.
Noise level: Have a handle on the noise level before you choose a diesel light tower, especially if it will be used in a residential area or near a noise-sensitive location.
Durability: Select light tower with high protection ratings such as IP65 and Zone 2 explosion-proof to withstand harsh conditions or flammable and explosive places.
Cost: To top it all off, consider the cost of the light tower and your budget so you can get the right balance of performance and quality for the price.
Warranty: Likewise, pay attention to the length and terms of warranty. Longer warranties and favorable terms can give you peace of mind and reduce the cost of ownership.
Sustainability priorities: Select solar light towers or lithium LED flood lights which minimize long-term costs and emissions, not to mention they align with green initiatives.
Mobility and compactness: Lithium battery light towers or LED flood lights suit mobile scenarios like event setups or vehicle-mounted operations. On the top of that, they are handheld.
Consider following factors when you’re having trouble choosing between hydraulic, electric, and manual light towers:
Ease of use: Consider the ease of use of different light tower type. Manual light towers require physical strength to set up and operate, while hydraulic and electric light towers are generally easier to set up and support remote operation.
Maintenance: Take the maintenance requirements of each type of light tower into consideration. Manual light towers require less maintenance than hydraulic and electric light towers, which have more moving parts.
Cost: Last but not least, balance the cost of each type of light tower and your budget. Manual light towers are generally the least expensive, while hydraulic and electric light towers are more expensive due to their higher technology content.
Combine the light tower with generator (diesel engine) and renewable energy sources offering more flexibility and multiple solutions. For instance, solar panels charge batteries during the day, while generators activate at night or during low sunlight, ensuring 24/7 operation.

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.
