Lumii H.P.S Lamps

What is HID lighting?

High Intensity Discharge (HID) lighting replaces the filament of a light bulb with a capsule of gas. The light emanates from an arc discharge between two closely spaced electrodes. This discharge is hermetically sealed inside a small quartz glass tubular capsule. HID lights require a ballast, which carefully regulates the voltage supplied to the capsule of gas.

High Pressure Sodium (HPS): Produces more red light. This promotes flower onset and production and is, therefore, more suited to the flowering/fruiting phase.

Therefore, it is common practice to use a HPS lamp for both vegetative and flowering – especially if plants have a very short vegetative phase. However, using HPS throughout can promote tall and spindly growth in many species.
