HID lighting hasn’t improved much in the past 30 years, but the new DEva 1,000-Watt Double-Ended HPS (high-pressure sodium) lighting system from Revolution Micro has changed the game. The low-frequency ballast is built right into the reflector, and the whole unit comes completely integrated, allowing the grower to simply plug and play. Couple this with their RLC-1 Smart Lighting Controller ($299), which will dim the lights to conserve electricity and reduce heat (or to simulate sunrise and sunset), and which controls up to 412 grow lights.
