Brand New BAY HYDRO Twin 600w 240v Ballast

Upgrade to the all new BAY HYDRO Twin 600w Digital Ballast and you'll see the benefits instantly! Our ballasts are made with the highest quality workmanship and strict quality assurance. We have located a team of engineers to create a BETTER QUALITY and more reliable Twin 600w Ballast, we also have a 1000w SE/DE High Frequency Ballast (operating at  >106Khz) and single 600w Digital Ballast. We have talked with MANY manufactures and have chosen the more superior factory, NOT the cheapest one like others. Our ballasts come with a 3 year warranty and have less than 2% defect rate. We stand behind our products 100%. Bay Hydro has been a trusted brand for many years and we will continue to provide the best quality products on the market and superior customer service. We also have 1000w & 600w HPS Bulbs to pair with our ballast for optimal performance. It is best to use our bulbs with our ballast as they are made for each other.

You will see increased efficiency & increased lumen output right from the start. Compared to traditional magnetic ballasts, Bay Hydro Digital Ballasts deliver approximately 30% more light for your garden. More Light = BIGGER Yield, you will provide light to your garden at a stable level with NO flicker or noise, Lamps will start up faster, and operate silently. These incredibly light-weight ballasts also produce less heat and they do not have nor need a fan (one less thing to break) as they are made with high quality parts.

Our BAY HYDRO 600w Twin / Dual output ballast runs on 240v and can power two 600w Metal Halide or High Pressure Sodium lamps. ALL of our ballast are dimmable and come with SUPER LUMENS to give 10% more light at the flick of a switch. Optional settings are Super Lumens, 600w, 400w, or 360w. 


BAY HYDRO Digital E-Ballast is a performance leader.

  • Operate both metal halide (MH) and high pressure sodium (HPS) lamps.
  • Up to 30% MORE LUMENS; faster growth, bigger harvests.
  • Unique graduated fin design for more efficient cooling. No cooling fan necessary means fewer moving parts and less chance of a broken ballast.
  • 3 years no hassle warranty.
  • Internal resin coating protects components for a long life..
  • Generator compatible.
  • Cuts off when a short is detected. For ultimate safety. VERY smart ballast !!
  • Completely silent.
  • Comes with Standard "S" style (Sunlight Supply Connection) lamp cord connection. We also have adapters if need for HYDROFARM Reflector / Hoods, Just let us know, ONLY $5 with ballast purchase.

Notes: Includes 240V power cord.

Why Digital Ballasts?

More Lumen Output - Up to 30% more lumens output than some old style magnetic ballasts ...More light equals more yield. We urge you to test this yourself with a good quality light meter. Be sure to also check how much power the ballast is using with an ammeter as many so called 600w magnetic ballasts now draw up to 750w as standard.

Stable Light Output - Excellent for Pharmaceutical-agriculture, laboratories and other uses where precise regularized output is essential.

Fast Start-up - It reaches full brightness in under one minute; magnetic ballasts typically take about twenty minutes.

Completely Silent - No noise or vibration of any kind

Produce Less Heat - Less heat generated by the ballasts allows cooler running of the environment. Less heat is less wasted electricity.

Longer Bulb Life - Lumen output loss over time, with the correct lamp, is dramatically less than with magnetic ballasts.

BAY HYDRO  ballasts are designed with internal microprocessor to soft start lamp and intelligently detect lamp voltage, current to prolong lts life hours. Dimmable features can save power at both input & output side. Staggered ignition to be more efficient to avoid inrush current. Perfect self-protection mechanism to prolong its life. 3 years warranty. YOU MUST KEEP YOUR RECEIPT AS THAT SHOWS DATE OF PURCHASE FOR WARRENTY COVVERAGE. Please SAVE your receipt.

Staggered Ignition
When group using, BAY HYDRO  ballasts will separately and randomly ignite lamps within 0~7 seconds to reduce inrush current.
Self-Protection Mechanism
Input  Protectionhigh/low voltage; lightening strike/ inrush current/ pulse group; overcurrent; brownout;
Output Protectionopen circuit; short circuit; end of lamp life; failure ignition; overvoltage; rectifying effect protection
Overheat protection In operation, inner heats will dissipate through case. When case temperature rise up to 85?, ballast will gradually reduce power to 80%; When case temperature reach to 90?, ballast will stop working until cool down to 70?, then returns to full power status.
