Power supply units - also called ballasts - are needed to operate HID lamps and are essential components of lighting kits, since the performance and durability of the bulb highly depends on the quality of the ballast used.
Here you have a selection of quality magnetic and digital ballasts so you can enjoy better performance and increaesd safety.
Among magnetic ballasts, you'll find ETI units (both Class 1 and Class 2), available for 250, 400 and 600W lamps.
On the other hand, electronic ballasts (also called digital ballasts) are much more efficient than magnetic ones. We offer you Nanolux, Lumatek and Bolt digital ballasts, so you can find your favourite model for your 250, 400 or 600W lamp.
