When it comes to having an indoor garden or greenhouse hydroponic garden, one of the most important things you need to consider is lighting, or what is called grow lights. Oneessential thing you need for lightinga garden or greenhouse is a good digital ballast, which is what runs the bulbs. When you go to the store to buy a ballast or search online for the best one, you will be welcomed with lots of options, which makes choosing very challenging. And it can be more challenging if you do not have any idea on how to get the best one for your needs.
If you are looking for a digital ballast for your garden but not sure how to get the best one, you’re in the right place. Today, we are giving you a guide to digital ballasts.
What is Digital Ballast?
Digital ballast is what supplies High Intensity or HID bulbs with power, and it also manages the bulbs’ capabilities. The ballast takes the input voltage and currentand controls it into pulses within specific frequencies to allow your bulb or lamp to run efficiently and optimally. And itdoesn’t matter if there are voltage fluctuations outside of the system.Therefore, when choosing a digital ballast, select those that can keep your HID bulbs working properly even if the input voltage suddenly changes.
Digital ballasts usually look like a rectangular box that is covered in aluminum heatsinks. They have electrical connectors, knobs, cables, and some may also have digital screens. What makes it digital is if it has a microprocessor. This enables the ballast to run MH and HPS lamps, and as well as make necessary adjustments based on the type of lamp or bulb it is running at a given time. Aside from that, digital ballasts can sometimes even compensate for lamp degradation.
Important Features in Digital Ballasts
If you are looking into buying digital ballasts soon, here are some of the essential features that you need to look for to get the best one.
- Dimming: The most basic feature that you can look for in a digital ballast is dimming. It should enable you to run your light at a lower wattage to save power. This will also allow you to adjust the light intensity depending on the needs of your plants. A good digital ballast will enable you to dim your lights at least 50% of the power.
- Bulb Protection: High-quality digital ballasts should have extensive bulb protection features. Some examples are line quality and ignition voltage control.
- Durability: The durability of a digital ballast depends mainly on the quality of the specific ballast that you are using, and as well as on the quality of your electrical connections. If you buy lower quality digital ballasts, they can go defective for as fast as 6 months. Higher quality ones, one the other hand, could last for more than 5 years. Also, a good quality digital ballast should be able to handle voltage fluctuations without noticeable changes in the performance of your grow lights.
- Radio Frequency Shielding: It is also important to choose a digital ballast that has radio frequency shielding. It’s because, without it, they can create a noticeable amount of Radio Frequency Interference. It means that they are capable of broadcasting a radio signal within frequencies, and this can interfere with other electronic devices and radio enthusiasts. It can also give you cable company visits because they can trace that the signal is coming from your garden. Therefore, when buying a digital ballast, make sure that it is built with proper RF shielding.
- Versatile: A digital ballast should allow you to simplify your garden and use it under different circumstances. A versatile digital ballast should be capable of running different wattage bulbs, running different types of bulbs, support for double-ended HPS bulbs, and as well as boosting, or running a bulb over its specified power output.
- Less Noise: A good digital ballast should be quiet. Some might come with small cooling fans that make little-to-no noise. However, if you get a lower quality digital ballast, it might emit noticeable noise, which can be annoying.
- Low Temperatures: If you have a hydroponic garden, the lights and other equipment in there can make your grow room or tent a little hotter. This is great during colder months. However, it is not good when the plants that you have stopped growing because of extreme transpiration. When buying a digital ballast, note that it is normal for them to get a bit warm, but not too hot that you can’t touch it.
