We are here to help you build you project!
Contact us to talk about it.

We offer a complete service regarding the installation of your outdoor lighting. We can supply you with a first study of the site and the placement of your luminaire. If needed we can commission for 3D-Dialux models based on your “dwg” files for the evaluation of large scale projects. This service will be charged.

Shipment logistic

The transport of the products you ordered should not become a headache for you. DTI-Energies© will handle the logistics of your orders to the address of the installation. We invoice you the transportation cost, but our logistics service is free of charge up to 20 units / light poles. Over 20 units, we charge 5% of the total transportation invoice value to manage your delivery.


Our accredited installation network is there to complete the installation of your order. These installers have been selected among the best players in the sector of public lighting, to ensure optimum quality.
