Cahill Hybrid Light Tower

A large infrastructure project in Western Canada needed a sustainable lighting solution. With limited daylight in the winter and shoulder seasons, reliable lighting was essential to get construction activities done safely. A few months into the construction, the contractor experience a few issues with their fleet of conventional metal halide and LED light towers. The light towers on site needed frequent refueling leading to the following problems:

  • Increased traffic and congestion
  • High fuel usage
  • High emissions
  • Increased chances of spills and accidents

The costs of fuel and threat of accidents prompted the contractor to look for a better technology.

Feeling the need to save costs, reduce the impact on the environment and avoid accidents, the contractor decided to replace the conventional light towers on site with Cahill's Hybrid Light Towers. The solar powered light tower featuring a backup diesel generator eliminated all of the problems the contractor was facing.

Capable of running 35 days or over before refueling, the light towers led to a sharp decrease in refueling visits. Considering the remoteness of the site, this led to cost savings from lower fuel usage, lesser frequency of refueling and oil changes and lower maintenance needs. Since the project used multiple light towers, these savings were tremendous.

The clean technology also virtually eliminated emissions and made it safe for the environment and the workers. Neighboring protected forests,it was important that the project also had a minimal environmental impact.

Cahill's hybrid light towers helped the customer achieve this by steeply reducing carbon footprint on site. With 83% lesser engine run time than conventional technology, Cahill's hybrid light tower is the safest lighting option available to industrial customers.

Aside from performance, Cahill's hybrid light towers are also convenient to use. Set up takes only minutes and the controls are simple and intuitive. The light towers also have an automatic day/night sensor that detects natural light and turns the light tower off without manual intervention.

Overall, over the course of the project, the construction contractor managed to tens of thousands of dollars in operational costs while decreasing the chances of accidents, spills and emissions. Even in the most extreme conditions in the peak of the winter when there was minimal daylight and temperatures dipped below -40 degrees, the light towers saw no dip in performance.
