Lighting Tips

PARsource HID systems are designed with flexibility so each unit can be utilized as an attached or remote fixture. An attached fixture is defined as a system with the reflector attached to the ballast. See Figure A for an example of an attached fixture. A remote fixture is defined as a system with...read more
Most light plans focus on average light levels and acceptable uniformity in the greenhouse. These figures can change significantly based on the spacing between lights and distance of the lights from the plant canopy. If general information such as width and length of the greenhouse is the only...read more
PARsource ballasts are designed to hang from a strut using the two C-brackets that ship with each ballast. Typically the C-brackets are attached to the ballast and hung over the strut. Some users may want to use chain to lower the ballasts. Follow the steps below if you choose to use chain: Cut a...read more
We recommend following the steps below when attempting to diagnose the cause of dim lights/low light output: Replace the lamp with another brand to see if you get the same results. If you get the same results, proceed to the next step. Check voltage supply to see if there is low voltage. If on...read more
We recommend following the steps below when replacing a lamp: Disconnect power to the ballast. Removing/installing a lamp into a powered ballast can cause ballast and/or lamp failure, and is a safety hazard. Always remove power from the ballast before performing any maintenance. Remove and replace...read more
When installing a light system for more than 30 fixtures, it is best to place them on a staggered start and shut down. Program your controller to make sure that no more than 30 lights come on or shut down at the same time. Programming a 5 second start time between each batch of lights should be...read more
To get the best performance from your bulb, replace the bulb at its “economic” life and not when the bulb burns out. The economic life is generally defined as 60% of the “Rated life” of the bulb. This is stated in hours of operation.read more
Remote ballasts offer many benefits over traditional attached fixtures. Less fixture obstruction of incoming light Ballast can be centrally located reducing electrical installation costs Ballasts remain cooler – prolonging the life of the ballast Easier to raise, lower, install and maintain lighter...read more
Here is a simple formula for calculating the energy costs of your light. Information to gather: STEP EXAMPLE 1. Get your energy costs in kW/hr from your utility bill. (KW) $0.12 2. Fixture Qty (FQ) 30 3. Bulb Wattage (BW) Use 1 for 1000W, 0.6 for 600W, and 0.4 for 400W 0.6 4. Hour lights run per...read more
When designing or constructing your greenhouse, add a temperature sensor in your gable area. Monitoring the temperatures in your gable area will help identify any issues with equipment located in that area. Expensive equipment such as gear motors or lights may be damaged with excessive temperature...read more
When installing or removing lamps from a fixture, it is best to use gloves. This will help keep the glass of the lamp clean from dirt and oils which will provide the best output and longevity and protect against any cuts from damaged glass.read more
When installing a new lamp (bulb), it is highly recommended that you run the lamp continuously for a minimum of 12 hours. This will increase lamp life, lumen maintenance, and stability of the lamp by allowing the gases in the arc tube to become completely combined.read more
