Hear it from the growers
Growers who light their operations with P.L. Light Systems, in their words.
The support of P.L. Light Systems has been tremendous. Their in-depth demonstration of the spectrum and efficiency of their lights is second to none. We had one fixture with a warranty claim, and it was replaced (exchanged) promptly with no hassle. P.L. Light Systems offers excellent value in their offering.
We absolutely love the [LED] lighting, and we were very happy with the service we received from P.L. Light Systems as well. Under your LED lights, the plants flower faster and the flowers are larger, which is more profitable since we sell by weight.
P.L. Light is a trusted long-term partner. They are nimble and flexible, going the extra mile to help our projects succeed. Their staff are polite, professional, and pick up the phone when we call. Their technical skill and humble, honest approach to their work when combined with the performance of their products and warranty support makes them a first-call resource for us when we have lighting needs.
On top of their excellent commercial products, P.L. Light Systems offers the best customer service in the industry. They are always responsive and flexible with any of our lighting support needs.
