This single T8 58 watt ballast has been designed to be as slim as possible. At just 21mm high it is perfect for tight spaces. This ballast unit features optimum cathode control, wide operational ambient temperature range, standard and side mount possibilities and also silent operation.
Great value lightbulbs. Huge choice too. Needed some lamps fast which were out of stock but their Customer Services moved mountains to get them to me in time for an outdoor birthday party. Highly recommend.
