Complete with a combination of high pressure sodium and metal halide bulbs, the Yield Lab 400W HPS+MH Air Cool Hood Reflector Grow Light Kit is a fantastic setup for growers looking to grow plants indoors and all year round. Offering a greater level of control over growing conditions, the Yield Lab air cool hood reflector kit includes:

  • Yield Lab 400W High Pressure Sodium (HPS) Bulb – 1 year warranty: With 30% more blue color wavelengths, the HPS bulb assists with the process of photosynthesis and stops plants from shooting up too fast (which results in spindly stems). The Yield Lab 400W HPS bulb is suitable for all Heliophile plants which prefer longer periods of sunlight, including camellias and roses.
  • Yield Lab 400W Metal Halide Bulb – 1 year warranty: With a color temperature of 5,500K, this metal halide bulb is best suited to the vegetative stage of the plant growth cycle. The Yield Lab metal halide bulb is an optimal choice for plants in the propagation stages and is particularly suited to lettuce, herbs and other green, leafy plants.
  • Yield Lab 400W Digital Dimmable Ballast – 3 year warranty: The stand out feature of this digital ballast is the dimmer control which allows the heat output to be significantly reduced on warmer days. The dimmable feature also allows for greater control of lumen intensity, with the ability to increase output in the latter stages of the growth cycle. The inbuilt safety features protect growers from overheating, ignition failure and both open and short circuit issues.
  • 6” Yield Lab Air Cooled Reflector Hood – 1 year warranty: The air cooled reflector hood is constructed from galvanized steel with a protective powder coating to guard against corrosion in humid environments. Manufactured with sponge seals surrounding the lens cover, the 6” Yield Lab reflector hood is 99.99% airtight and has been especially designed to increase airflow for improved cooling function.

  • 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 HPS+MH air cool hood reflector grow light kit includes 1 x HPS bulb, 1 x MH bulb, 1 x digital electronic ballast, the air cooled reflector hood , ceramic socket, a hanging ratchet kit and a free timer . This set up is completely silent when operating; this effectively eliminates that annoying buzz associated with some grow light kits.

Cover too loose.
Size: 300A Fuse Holder
Nice looking, decent quality, versatile for different gauges. My only complaint with this holder is the cover doesn’t stay on very well, bought 3, and all 3 pop off easily, you will need to zip tie on.
