- This is also known as soft starting, which minimizes the damage to the bulb and increases its PAR life (PAR represents the plant usable light; it's what plants "see" and use, versus lumens which are what people see).
After one year of use the plant usable light coming from bulbs that are run on digital ballasts has decreased only by 20-25% where as the same bulb being used in the coil type ballast would have lost 50-60% of its plant usable light over the same period of time.
Magnetic coil type ballasts are also known to cause the bulb to flicker or strobe. This takes place so quickly that the neither human eye nor light meter can pick it up. Eclipse LED digital ballasts provide a uniform power supply to the bulb, thus eliminating the flickering from the bulb and saving you money with fewer bulb replacements.
Another great feature of digital ballasts is the ability to run both MH and HPS bulbs on the same ballast without having to flip a switch (it should be noted that not all digital ballasts on the market are programmed (or optimized) to do this properly, Eclipse LED digital ballasts are). Research shows that Eclipse LED ballasts are optimized for the most efficient HID output available. Our digital ballasts are designed to give you maximum light output at the best efficiency possible. Compare the Eclipse LED digital ballasts with similar wattage magnetic ballasts.
