The original supplier of Quantum Ballasts, R & M Supply, has gone out of business. Hydrofarm has purchased the Quantum ballast brand from R & M and are continuing the brand with the exact same product. All Quantum ballasts in 1000w, 600w, and 400w models are now available for purchase. When you order from Growers House, the Quantum 600w ballast comes with the 120v power cord, but this ballast is also compatible with 240v power cords (not included).

The world of indoor gardening was changed forever with the introduction of digital lighting by Quantum Horticulture. A new alternative to heavy, noisy, power wasting core and coil ballasts had reached our shores, the Quantum Digital Dimmable grow light ballast. Quantum Digital Dimmable ballasts will strike both Metal Halide and High Pressure Sodium lamps without having to flip switches or change wiring like a standard core and coil ballast, while also saving you a noticeable amount of power on your electric bill. Quantum Digital Ballasts have shown savings of up to 30% reported from Quantum laboratory testing facilities compared to standard core and coil ballasts.The Quantum Ballast dimming switch is located on the front of your ballast just above the lamp cord. Always allow 30 seconds between the different output settings to allow your ballast to draw the proper amount of power and charge your bulb to the desired setting.

You will notice how much cooler your new ballast runs and how lightweight it is. The base of the unit gives you many options of how you would like to mount it.

Like everything new and exciting there is a downside. Many companies eagerly came out with technology too quick that has not been tested in real life gardens. Many of these ballasts cannot stand up to the atmospheric demands that gardeners put on their equipment. This has led to high failure rates amongst our competitors. These failures include RF (radio frequency) interference, burnt circuit boards, and faulty cord ends.

Finally, the world of digital lighting is about to change in a big way. Quantum Series Lighting is now the paradigm of lighting technology. Quantum Horticulture analyzed the mistakes and failures made by others in their quest for digital lighting, and utilized that knowledge to bring us the best in high intensity illumination.

The Quantum Series ballast is covered by a full Three year warranty under normal use. You can increase the life of your ballast by always making sure it is kept clean and out of extremely damp conditions.

    Good for the price Review by LeadSled
    Overall Rating
    Have been running 4 Quantum 600s for about 2 years now. Got 2 with the Digilux bulb package and 2 with the MaxLume bulb package. All are of comparable brightness and spectrum. Digilux bulbs last longer and stay brighter longer on these ballasts. One Quantum cooling fan started making a whining noise like impending bearing failure. Replaced the fan with a same size fan from a computer store with no problem. All 4 still going strong. (Posted on 12/24/2015)

    The Quantum operates with just a whisper of fan sound. It also makes less interference radio noise than my Efusion unit. Have not tried the dimming feature but plan to use it when I have a smaller inside garden as plants go outside this Spring. (Posted on 2/13/2015)

    I've used these since they came out about 5 years ago. Have 6 at this point and have yet to have one fail. One has a fan that is a little louder than the others, but that only started happening after 4 years and I know those fans aren't made for very long term use. (Posted on 7/18/2014)
