Portability is a key factor for many users, and the EP730 delivers on this front. With a weight of just 2.5 kg and a compact design, it can easily be transported between classrooms, meeting rooms, or conference venues.
Additionally, the EP730 is designed with energy efficiency in mind. It incorporates a dynamic power-saving feature that helps reduce energy consumption and extends the life of the lamp. This not only benefits the environment but also reduces the overall cost of ownership for users.
