    • Ceramic Metal Halide (CMH) grow lights may be a relatively new kind of HID grow light, but it has significantly impacted growers. With far better results than conventional HPS and MH grow lights, CMH Grow Lights offer a full-spectrum of light with lowered heat output. Albeit a bit expensive than the rest, CMH Grow Lights make up for it by saving energy costs. The best part about these bulbs is that they last longer than their counterparts, with a difference of almost 14000 hours.

    How long do CMH bulbs last?

    24,000 Hours. CMH grow lights will last over 24,000 hours and will maintain at least 80% of its brightness, efficiency and intensity. Compared to MH & HPS bulbs which start to lose their efficiency after 10,000 hours CMH lights are a great value in the long run. Check out our guide on How & When to replace your Grow Bulbs or our comprehensive guides on other types of grow light bulbs in our Learning Center.

    So, if you’re looking for highly efficient grow light bulbs to make an impact on your plants’ growth, then connect with Groindoor.com today. Make your indoor growing glow with our vast supplies of CMH grow lights!
