Why Digital Ballasts?

What is a Digital Ballast?

Digital ballasts use switching electronics and small frequency inductors to control current and voltage to the lamp. They contain a ‘microprocessor’ similar to what’s used in a home computer. This allows  Electonic Ballasts (or E-Ballasts) to run both M.H and HPS lamps, make adjustments for based on the type of lamp it’s running, and will even compensate for degrading lamps by increasing output! (Also Quantum’s have a sealed Bearing Cooling Fan that has enabled massive reliability over the Lumateks )

The higher frequency excites the lamp’s gas within the arc tube to run at a much higher frequency. Old style magnetic ballasts cycle at 50 times/sec (hertz), so is effectively like strobe lighting that can be seen through a digital camera. The Quantum Digital Ballasts cycle at a massive 28,860 times/sec (hertz) so is providing non-flickering constant light that has a large impact on yield. Light output is also increased through constant distribution, lamp efficiency and increased lumen output. Lamps will also stay brighter for longer giving them increased life. This is particularly true for metal halides that are very sensitive to the voltage supplied to the lamp.

Power Efficiency

Digital Ballasts are extremely power efficient and is seen as one of the major advantages in comparison to Magnetic Ballasts.

(Around A third less power used )  Many happy growers are already reporting huge savings on their power bills!

All Our Digital Ballasts  incorporate “Soft Start” technology and have very low start up currents(Amps). This is a huge advantage for growers using multiple ballasts and allows more to be turned on at one time of a single circuit or timer. Most timers have 10 – 15amp contacts and can usually only handle 2 x 600w magnetic ballasts (4.8amps each) at a time before the contacts go and you will find your timers don’t turn on or off, or you blow a circuit fuse.
The following data shows the extremely high start up currents and running watts on standard new magnetic Core and coil ballasts within Australia. Brands A and B are some of the most widely used ballasts in the country! Older used ballasts have an even higher start up current and wattage use, making them even more inefficient!

Amps Watts
Startup Min Max Min Max
Digital 600W 1.95 2.47  2.58 611.7 614.7 
Brand ‘A’ 600W 4.85 3.25 3.30 707.7 749.7
Brand ‘B’ 600W 3.82 2.90 3.01 639.1 707.8

This data shows why so many customers blow their Timer contacts and mains fuses when only igniting 2 x 600w lights at the same time. While the digitals can be ignited at up to 4 lights at a time off a single 10amp fuse or timer!

Also when connecting large numbers of ballasts you can you can turn on (or stagger) many more lights at a time more frequently because they reach full output within approximately 2 minutes (not 20 minutes like magnetics).

Another thing that happens with larger setups is when connecting multiple ballasts your power voltage drops as you use more lights, which means you lose light output .

Digital Ballast Benefits

More lumen output per/watt producing 20-30% more light than standard magnetic core and coil ballasts

‘Soft Start’ no ‘spiking’ very low start up current and running current, making them extremely power efficient. No more blown contacts!

Reaches full brightness in approximately 2minutes (rather than 20 minutes)

Fully compatible with both M.H and H.P.S lamps.

Small Compact design that runs Cooler with sealed bearing cooling fan

Dimmable down to 50%

2 Year Warranty with proof of purchase.

C-Tick Electrical Approved

In a nutshell ,

Digital Ballasts generate 20% more Lumens that penetrate down 30-50% Deeper meaning up to 20-25% Yield Increase – BUT using a Third Less Power !!
