Yield Lab 315w 3100K Ceramic Metal Halide (CMH) Grow Light Bulb Item# CU-CMH315-3100K-B


If you’re growing a plant or two and you’re tired of always switching from MH to HPS bulbs when it’s time to flower, the Yield Lab 315w Ceramic Metal Halide (CMH) Grow Light Bulb is the light you’ve been looking for. Perfect on its own for smaller plants and flowering bonsai’s and even better when paired with another CMH bulb for better light than ever, these grow lights will give you more than enough spectrum to take your smaller plants from seed to harvest all with a single light.

Ceramic Metal Halide (CMH) grow light bulbs are the latest in indoor horticulture. The spectrum these lights give off is an incredible jump over standard Metal Halide bulbs, giving you a more balanced white light (versus an MH bulb that gives you an extremely intense blue than simply seems white). This light is better absorbed by plants than MH bulbs and HPS bulbs, and will also give you more resin growth than standard HPS and MH bulbs ever will, so there’s no need for a UVB  fluorescent bulb for all that extra resin production you’re after.

While installation is different than standard and double ended HID grow bulbs, the process is still pretty simple:

  • Align the prongs at the bottom of the bulb in to socket fixture
  • Once aligned, slowly twist the bulb so the prongs slide along the grooves in the socket
  • Ensure it's secure in to the CMH fixture, and you're ready to grow

If you're interested in taking your grow to the next level, or you're already using CMH's and simply need another bulb, the Yield Lab 315w Ceramic Metal Halide (CMH) Grow Light Bulb will give you the quality you want and the coverage your plants need.

Bulb Specifications:

  • Wattage Per Bulb: 315w

  • Note: This lamp is only compatible with CMH grow light reflectors, and will not fit in to the socket of a double ended or single ended HID grow light fixture
