LED lighting has been on the wider energy efficiency agenda for some time, but right now there is no better technology to offer the highest level of energy and cost savings, while still maintaining or improving lighting performance.
We understand the growing needs to reduce carbon emissions, electricity bills and annual maintenance costs. Zeta’s products deliver on energy and cost savings as well as offer an excellent maintenance free solution.
Energy and maintenance costs are rising dramatically and with lighting accounting for approximately 40% of an average electricity bill, it now makes commercial sense to switch to low energy lighting that can offer as much as an 80% saving in energy and carbon.
