The HLG Saber 100W from Horticulture Lighting Group (HLG) UK/EU is a high-efficiency, waterproof LED bar designed with DIY and customizable grow setups in mind. Featuring 220 Samsung LM301H diodes and 10 deep-red LEDs, the Saber 100W reaches up to 120 W per board and delivers broad, even light coverage across small to medium grow spaces. This 44‑inch passive-cooled fixture is made from durable, weather-resistant materials and operates silently, ideal for noise-sensitive environments. Although the Saber 100W itself doesn’t include a power supply it’s compatible with 36 V DC drivers, supporting currents up to 3,200 mA. But if you’re thinking about another more powerful or a different lighting system, then check out the HLG 300 V2 Rspec or even the HLG 550 V2 Rspec.
