P.L. Light Systems is a manufacturer of LED and hybrid horticultural lighting based in Canada and focused on North America, with over 45 years of experience serving commercial growers since 1981. The company designs and engineers customised lighting solutions for commercial greenhouses and indoor farms, tailoring spectrum, intensity and photoperiod to specific crops including vegetables, cut flowers and cannabis. Their LED fixtures are engineered in-house and certified for safety and wet-location use in greenhouse environments. Referrals suit them best if you work with large-scale commercial growers who need customised lighting solutions rather than off-the-shelf products.
