ETI S.A. was founded in 1964 and is currently one of the most important manufacturers of ballasts in the world with branch offices in 42 countries. Many components in common use today were initially developed by the Spanish company and later adopted by other manufacturers. For half a century, all stages of production - from development to final production - have been taking place in the company's own facilities. ETI also has a special laboratory which carries out all product tests, including benefit assessment analyses and actual performance tests. In addition to ballasts for gas discharge lamps and fluorescent lamps with an output from 150 to 600 Watts, ETI also offers kits and complete grow sets both for beginners and experts.
