Lumatek Dimmable Ballast 400W
Lumatek digital ballasts get an upgrade with their new dimmable ballasts to allow greater flexibility in your growing area while reducing the cost of buying multiple ballasts.

Ideal for when you want to avoid the heat of the summer months, if you need a boost for flowering or you want to establish young plants, these Lumateks are excellent value at less than the price of two compact ballasts with all the benefits of digital electronic ballasts.

The Lumatek Digital Dimmable ballast features the same technology as the standard Lumatek electronic ballast including soft start technology and a five year guarantee, these ballasts are highly recommended.

The manufacturer recommends only using specific lamps for specific settings - if you want to use the ballast at 400W then use a 400W lamp rather than turning down a 600W lamp, otherwise you will lose efficiency.

Please also note that it is not possible to use Metal Halide lights with the Super Lumen setting, only Dual Spectrum and HPS lamps are suitable. 

The 600W ballast can be adjusted to 250W, 250SL, 400W and 400 Super Lumen.
