HPS Dual-Express 600w Lamp

If you’re looking for vigorous plant growth and high yields in a medium to large setup, the Cultilite HPS Dual‑Express 600W gets the job done. This heavy-duty, full-cycle grow light is equipped with a dual-spectrum switch that delivers blue-rich metal halide for strong vegetative structure, which can then be switched to red-orange HPS for explosive results during flower. Drawing 600 watts, it provides deep canopy penetration and broad coverage — with a durable ceramic socket and sturdy ballast that ensures stable performance through back-to-back grow cycles. Because of its heat output and energy draw, it will need to be paired with adequate ventilation. For smaller spaces or to keep things cooler, look into the HPS Dual Express 250W. If you're interested in max bloom intensity and don’t necessarily need a lamp for veg, the HPS SON‑T Agro 600W is a great choice — offering focused red-spectrum power for boosted flowering.
