When Yield Lab decided to create the Yield Lab Professional Series 120/220v 630w Dual Bulb CMH Open Wing Complete Grow Light Kit they made sure to produce a light that will give you plants a wide coverage area without sacrificing intensity. Whether you’re growing with hydro or in soil, this grow light carries a spectrum that will give you a more balanced white light compared to an MH bulb that gives you an extremely intense blue than simply seems white.

Ceramic Metal Halide (CMH) grow light bulbs are one of the latest and best styles of light in indoor growing. The 3100k temperature of these bulbs can be absorbed at a higher rate by plants than MH bulbs and HPS bulbs. The light also emits UVB that tends to produce resin in plants, so there’s no need for a secondary UVB fluorescent bulb or T5’s to do that.

The Open Wing reflector offers openings at the top that help disperse heat away from the reflector. Unlike cool hoods that need a fan to help them exhaust heat, this reflector allows heat to escape from the sides of the reflector to avoid sending too much heat down on to your plants.

An added benefit of the open wing design is the closer relationship between your cooling/exhaust system and your lights. Meters and gauges measure the ambient temperature of your grow room, which may not reflect the temperature at the canopy level (which tends to be higher because of the heat it absorbs up top). When your meters tell your cooling or exhaust systems to turn on it’s because your room tells it to- not the canopy, which can be anywhere from 5-10 degrees higher than your room. Because this reflector exhausts heat from its sides, your meters will read the heat coming from your light rather than the heat in your room. This will give you a far more accurate temperature reading than standard lights will, and makes fixing growing mistakes (like heat stress) a lot simpler.

So if you’re looking for a grow light that’ll give you great coverage without a ton of heat buildup, the Yield Lab Professional Series 120/220v 630w Dual Bulb CMH Open Wing Complete Grow Light Kit is what you need. Simple to setup, easy to use, and highly effective, this CMH grow light will get your plants from seed to harvest without changing a bulb.
