Read Answers for Quantum Digital Ballast - 1000W 120V/240V HPS/MH

How many amps does it draw at 120V & 240V? -Jim

This 1000w Quantum Digital Ballast draws 8.9 amps on 120v and 4.3 at 240v. -Greners Staff

When dimming a 1000w ballast do you need a 750w bulb for 75% and 500w for 50%? I've seen 750w grow lights but I have never seen a 500w grow bulb. I really want to run 600w. -Max

The directions for the Quantum 1000w dimmable ballast suggest using a 1000w bulb in all dimmable configurations. At the 50% setting this will reduce your power consumption to about 500w with your 1000w bulb. This will also reduce heat, making it more comparable to a 600w set up. Ideally, this is used to dim lights during hardening periods when moving from Veg to Bloom cycles, however many use it to run a cooler setup during hotter summer months when heat control is problematic then turn it up in winter. Digital bulbs are recommended when using electronic dimmable ballasts. -Greners Staff

Please describe the process of changing wiring from 120v to 240v. -Stevve

Simply change the cord from the standard 120v to an additional 240v, available here: -Greners Staff

Wondering about the warranty for Quantum ballasts either 1000 or 600.We live in Victoria BC Canada. Do we have to ship? Also what type of bulbs does the Quantum use. Will it take Plantmax 1000 watt PX-MX 1000/7200K? Can we have a reduced rate for an order of 8? -Heidi Foord

Quantum Ballasts have a 3 year no-hassle warranty. We handle shipping for the first 30 days, after that you will have to pay for return shipping. The Quantum Ballasts will use nearly any MH or HPS bulbs, but will get best results from bulbs designed specifically for the frequency of electronic ballasts. You can contact us at to discuss bulk discounts. -Greners Staff

We welcome you to the latest in digital lighting technology. Quantum Series Lighting ballasts have been specially designed to perform in the extreme atmospheric conditions found in indoor gardening situations. Quantum Horticulture has gone through great lengths to ensure that this device complies with Part 18 of the FCC rules and regulations.

Quantum Series Lighting 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. Savings of up to 30% have been reported from our laboratory testing facilities compared to standard core and coil ballasts.The 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.

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.
