In the past three years I have purchased a number of TVSS products from various manufactures and suppliers. I can honestly say that I do not think there is one TVSS application I have not been involved in. Total Protection Solutions products are the best TVSS units I have ever purchased. I have a number of customers that are experiencing two to three times more life out of their light bulbs & ballasts, ….not to mention a decrease in maintenance and downtime costs of between 20 and 40%.
