Plantmax 1000W HPS Lamp, 2000K High Pressure Sodium Grow Bulb, Pack of 6

Plantmax 1000W HPS Lamp for Flowering Rooms

A 1000 watt sodium lamp remains a workhorse for flowering and fruiting under HID fixtures. This Plantmax lamp is rated at 140,000 initial lumens. Its 2000K color temperature gives the warm, red-orange light that sodium lamps are known for. That output places it squarely in the bloom stage of the grow cycle. The maker's spectral chart peaks in the yellow to orange range, with smaller lines in the blue and deep red. Average rated life is 24,000 hours. The lamp uses a mogul E39 base and a clear ET25 glass envelope. It runs in any burning position, so it suits horizontal hoods and vertical setups alike. The ANSI code is S52, which identifies the sodium ballast type it needs. Plantmax backs the lamp with a one year warranty. This listing includes six lamps, enough to relamp a small room in one go. Many growers pair a sodium lamp with metal halide for a full-cycle schedule.

Running High Pressure Sodium Lamps Well

Install each lamp only with the fixture unplugged and the socket cool. Handle the glass with clean gloves or a soft cloth. Thread it firmly into the mogul socket until it seats without forcing. Pair it with a ballast rated for this wattage and the S52 designation. A magnetic ballast or an electronic ballast that lists this lamp type will both work. Allow several minutes for the arc to warm up to full brightness after striking. After a power interruption, the lamp needs to cool before it can restart. Hang the reflector at a height that keeps leaf temperatures comfortable at the canopy. Light output falls gradually over time, long before the lamp stops working. Many commercial rooms replace sodium lamps on a fixed schedule to keep intensity consistent from run to run. Write the install date on the fixture so each lamp can be tracked. Spent lamps contain mercury, so recycle them according to local rules.
