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.

Complete Digital Installation & 12 Week Grow Guide:

Each Yield Lab Grow Light Kit comes with an easy-to-follow installation guide that walks you through setting up and using your brand new grow light. Our 12 Week Indoor Grow Guide will show you how to maintain a healthy indoor grow room including lighting and feeding schedules, pH and PPM levels, and optimal environmental conditions like temperature and humidity.

The Yield Lab Dual Bulb CMH grow light kit will give your plants the spectrum they need to veg, flower, and harvest all in one light. With a CMH grow light all you have to do is install the all-in-one unit above your plants, twist the bulbs in to the reflector, plug the grow light in to a 110v or 220v outlet, and in minutes your garden is getting a better light than your other high intensity discharge bulbs.

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.

The hood design is great for focusing all of that light you’ll give your plants directly down on to your plants. Made of highly reflective material, the hood reflector has the ability to focus intense CMH light down on to your plants without too much unnecessary spread, ensuring the majority of the light it emits isn’t wasted.
Installation couldn’t be easier! There’s no need for a complicated setup with these lights: just connect the hanger to the ballast, use the rope hangers to hang the light above your plants, plug the power cord in to your outlet, and in minutes your grow room is illuminated. Even better, this electronic ballast has minimal EMI (electromagnetic interference) with your electronic devices, unlike digital ballasts. So with this light you’ll be able to grow what you need without interrupting your cell phone, wireless networks, TV’s, and other electronic devices .

If you’re looking for a grow light that’ll give you an intense spectrum without all the EMI you get with a digital ballast, then you found what you’re looking for with the Yield Lab Professional Series 120/220v 630w Dual Bulb CMH Complete Grow Light Kit. With CMH grow lights there’s no switching out bulbs when it’s time to go from vegging to flowering: just adjust your light cycles and you’re good to grow.
