Lumatek Ballast 400W - 250W

Lumatek 400W Dimmable ballasts feature dimmable stable light output which are ideal for pharmaceutical agriculture, laboratories and other uses where precise regulated output is essential.

These have a reaaly fast start up and they reach full brightness in under one minute making them a lot faster than magnetic ballasts.

Due to the design and running these dimmable ballasts are completely silent. They are small and compact in design eg a 600 watt 230 volt ballast weighs less than 3.75 kilos compared to heavy magnetic ballasts.

They produce less heat and are manufactured with cut-off circuitry so they cut off when a short is detected for ultimate safety.

Their design ensures a longer bulb life and minimum lumen output loss over time (with the correct lamp) is dramatically less than with magnetic ballasts. Lumatek ballasts are also fully interchangeable Lumatek ballasts can light both HPS and MH bulbs (please note that the super lumen switch cannot be engaged on metal halide bulbs).

Optional selectable dimming levels at 250W and 400W levels. Boost your output 10% by switching to 400SL.
