VIVOSUN Exclusive Soft Start & Slow Light Start-Up Technologies for Much Longer Service Life!
Your Wonderful Choice for Flourishing Harvest!
VIVOSUN digital ballast will save you more power because of their soft-start feature. Your bulbs will potentially last longer before they will need replacement. Most of them also won’t try to immediately re-fire a lamp if it goes out (Power outage or any other reason) and will wait some time. Then re-try. A standard ballast will continuously try to light the bulb up. They also don’t get as hot as a regular one.
Fully compatible for metal halide and high pressure sodium bulbs.
Ensure that the bulb and ballast have the same wattage before powering on.
Reduce wastage and improve usable efficiency of power supply equipment capability.
Open/short circuit protection under input terminal/internal heat and radio frequency for critical components
Cautions
Do not operate the ballast before you read & fully comprehend the product instructions.
The ballast can not ignite lamp which is overheated. Re-ignite the lamp before giving the lamp sufficient time to cool down.
Notice: Set ballast to the same watt option as the matched bulb before started
