Sylvania Grolux Lamps

Sylvania Grolux Lamps


The Sylvania Grolux Duel Spec HPS Lamp has a high lumen output. The large majority of this is in the orange/red spectrum, with some blue mixed in making them ideal for both veg and flowering cycles. Sylvania has been involved in the hydroponic industry for many years, and remain a market leader gaining a well-respected name for quality all round lamps at a great price. Horticultural lamp light output will decrease with use. It’s recommended that growers replace lamps at regular intervals to maintain optimum yields.


  • The Grolux will give you optimum plant growth and flowering.
  • The colour has been adjusted to provide a broader spectrum of light making it ideal for both vegetative growth and flowering.
  • 6 month guarantee.
