Introducing the world’s first 1000W Ceramic Metal Halide lamp.

As a direct replacement for your existing 1000 watt HID fixtures, this 4K 1000W CMH lamp provides the absolute highest photosynthetically active radiation (PAR) to your specialty flowering plants.

Emitting an astonishing PPFD and with an extremely high CRI, this lamp will not only increase your overall dry weight but will also raise the quality of your harvest.

Grower’s Choice has continuously produced the world’s most accurate spectrum, closely replicating the sheer power of the sun. By using existing double-ended fixtures with this new 1000 watt CMH lamp you can completely overhaul the lighting in your facility, and enjoy watching your yields increase as your temperatures decrease.
