Features of Lightspeed CMH 315W 3100K Double Jacketed Lamp


The Lightspeed CMH 315W 3100K Double Jacketed Lamp is a highly efficient lighting solution for indoor gardening that produces full-spectrum light with enhanced UV and far-red components, resulting in brighter, healthier plants.


With a double-jacketed design, this lamp is more durable and has a longer lifespan compared to other single jacketed lamps. It also runs cooler, reducing the risk of plant damage and eliminating the need for additional cooling equipment.


The Lightspeed CMH 315W 3100K Double Jacketed Lamp has a color temperature of 3100K, which is ideal for the vegetative stage of plant growth. It uses a ceramic metal halide (CMH) technology that produces more PAR per watt than traditional MH/HPS bulbs.
