Product Spec Sheet

Introducing the world’s first 1,000W Ceramic Metal Halide lamp. As a direct replacement for your existing 1,000 watt HID fixtures, this 1,000W 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.

30 years been using old-school magnetic ballasts. Friends bug me to get into the 21st century. Can't stop raving about how nice these new bulbs are
