Commonly Asked Questions
What is included in my High Pressure Sodium ballast kit?
All our Kits come with a ballast, ignitor and mounting hardware. All ballast that are above 200W come with a capacitor.
Is a High Pressure Sodium ballast the same as a HPS Transformer?
Yes- It is just another way of describing a HPS Ballast.
Do I need the lamp wattage to match the HID ballast wattage?
Yes- The HPS Ballast are designed for a specific wattage. There is a chance that using the improper lamp will cause a fire and can also damage the bulb and ballast.
Is HPS sodium good for growing plants?
Yes- High Pressure Sodium is extremely effective in the budding process in most plants.
Can I use HPS sodium in my Aquarium?
High Pressure Sodium give off a yellow/orange tint. This is not very visually appealing to most aqaurists.
Do I need a capacitor with my High Pressure Sodium Ballast?
Yes and NO- All higher wattages come standard with a capacitor (200W and Above) and a capacitor is not standard with ballast that are 150W and below. The amps of a lower wattage ballast do not usually warrant one. Please check with an electrician to see if the amperage draw is too high.
