Matrix 1000W DE HPS Lamp - 2100K Double Ended HPS Bulb for Flowering

Matrix 1000W DE HPS Lamp for Flowering Rooms

This is a 1000W double-ended high-pressure sodium lamp rated at 2100K, the warm, red-heavy color point used in flowering rooms. The arc tube is held at both ends, and the lamp connects through a lead wire at each end instead of a screw base. That layout lets a matched double-ended fixture drive it hard while the arc stays steady over long bloom runs. At 2100K the output sits squarely in the flowering band, with most of its energy in the orange and red wavelengths. Growers fire it up once the room flips to a 12-hour photoperiod and keep it running through ripening. It swaps into a spent position in a 1000W DE fixture without touching the reflector or the ballast settings. The spectrum is thin in blue light, so this is not a veg lamp. Plants that spend veg under it alone tend to stretch between nodes. Most rooms veg under metal halide or LED and switch to this lamp when flowering starts. Like other HPS lamps, it holds a small amount of mercury and sodium. A spent lamp belongs with a lamp recycler rather than in the trash.

Installing a Double Ended HPS Bulb and Planning Replacement

Turn the fixture off at the breaker and give the old lamp time to cool before opening the reflector. Handle the new lamp with clean cotton gloves, since skin oil left on the glass bakes on and creates a hot spot. Seat the lead wire at each end into its socket slot without bending it, then slide the sockets inward until they click. Check that the lamp sits straight across the reflector before closing it up. Set hanging height from the fixture maker's guidance, then confirm it with a PAR meter at the top of the canopy. After a power blip, a hot HPS arc will not restrike until it cools for several minutes. Expect a short dark period before the room relights. Log the hours each lamp runs from the day it goes in. Output fades slowly, and the usual signal to swap is a reading near 75 to 80% of the new-lamp level. Changing every lamp in a room at the same time keeps intensity even across the canopy. Keep a boxed spare on the shelf, because a lamp that fails mid-flower costs more than the lamp itself. Pack the spent lamp in the new lamp's carton for the trip to recycling.
