Maintaining Efficiency

Maintaining Efficiency

P.L. Light Systems provides more than just lights. LightCare is the company’s service and maintenance division, offering full service maintenance and testing for lighting systems.

LightCare was initially created to help educate growers about how to maintain their lighting systems to maximize efficiency, saving growers money and keeping optimum crop performance. LightCare can help show growers how much money can be saved by employing small maintenance measures.

LightCare offers these tips: 

•  Clean your components. Even if dirt is not visible, it is important to clean bulbs and reflectors once a year to ensure maximum life of your system.
•  Have your bulbs tested. A bulb should be changed after 10,000 to 12,000 hours of use. For every 1,000 hours, the useful light output decreases by 1 percent. After 10,000 hours, 10 percent of your light output has been lost, but you’re supplying the same amount of electricity and lowering production.
•  Have your reflectors tested. Depreciation in light levels may not be obvious, but your reflectors could be blocking as much as 10 percent of the light generated from the bulb. Depending on greenhouse environment, a reflector is usually ready for reanodization after five to seven years. Reanodization is an inexpensive preventive maintenance technique. LightCare can measure the efficiency of a reflector and provide an analysis as to whether reanodization is recommended.
•  Have your capacitors tested. A capacitor’s ability to sustain and balance power will decrease over time, causing issues with breakers tripping or conductive heat issues. An imbalance in power can be a source of useful light loss and therefore, production loss. Capacitors should be replaced if their values have declined more than 11 to 15 percent. The LightCare testing facility will take a capacitance measurement of your capacitors and provide an analysis as to whether replacement is necessary.

The LightCare team measures and tests installations in the field and at the laboratory in order to gain insight into the efficiency and quality of the installations’ components.
