Optimized for high-frequency, double-ended high pressure sodium (HPS) and metal halide (MH) lamps, the Lightspeed 1000W DE Ballast is a true workhorse! Now is the time to upgrade your garden to the intense PAR output of a double-ended high pressure sodium or metal halide lamp, and this is the place to start.

Experience the improved reflectance, light delivery, and optical properties a properly powered double-ended bulb will produce. This high-frequency ballast from Lightspeed keeps a steady 120MHz frequency at the lamp to truly reach the µMol and PAR potential of your lamp.

The versatile multi-voltage Lightspeed 1000W DE Ballast can switch between 120V, 208V, or 240V and is easily integrated into your current grow setup. Featuring a dimming switch set to 600W, 750W, or 1000W, the Lightspeed high-frequency DE ballast will reliably power high pressure sodium and metal halide lamps of the corresponding wattage. Additionally, there is a super lumens switch for the grower that likes to push the limits of their 1000W DE bulb and boost it.

For exceptional results, pair the Lightspeed 1000W DE Ballast with the Lightspeed DE 1000W HPS lamp. With an optimal 2100 µMol output and deep red spectrum the Lightspeed DE grow light will exceed all your expectations. Lightspeeds’ double Ended HPS bulb arc tube was designed specifically for hydroponic gardening. The refined output of our bulb balances the spectral output to help prevent internodal spacing, providing just the right bloom spectrum to maximize your flowering stage and produce large, tasty fruits and flowers. With strong PAR output and a wide spectrum the Lightspeed Double Ended Metal Halide 1000W bulb was created for maximum vegetative growth. Lightspeeds’ Double Ended MH provides just the right spectral color balance to promote huge vegetative results along with tight internodes and minimal stretching.

The Lightspeed 1000W DE Ballast includes a removable power cable and is plug and play ready. Built to be lightweight and portable, it is intended for use with any HPS/MH DE reflector designed for remote ballast installation. This double-ended ballast has a lamp lighting range of up to 60 feet.

With through-ballast venting and CAD heat dissipation fins integrated into the aluminum casing you can expect a cool and quiet ballast that performs as promised. The anodized finish provides a layer of protection for the long life of your Lightspeed 1000W DE Ballast.
