Growlite Real Red 1000W Double Ended HPS Lamp

1000W DE HPS Bloom Lamp for Commercial Flower Rooms The lamp pulls 1000 watts at 250V and 4.7A through a T10 double-ended bulb. Initial output is 140,000 lumens at 140 lm/W. PPF lands at roughly 2000 µmol/s in the 400-700nm range, useful for canopy-level intensity math. The Growlite Real Red 1000W DE HPS sits at 2000K color temperature. That places the lamp in a deep red spectrum HPS profile in the Flowering / Bloom growth phase. Rated life runs 20,000 hours, ANSI designation is S52, and CRI is 25. Operating voltage is 250V at 4.7A through a K12x30s base. Bulb diameter caps at 32mm, max overall length is 394mm, and light-center length is 197mm +/-2mm. Pair the lamp with an electronic DE ballast such as the Growlite HDE Switchable for predictable ignition. Double Ended HPS Flowering Output and Pairing for 2000K HPS Bloom Bulb Rooms Growers typically place the lamp horizontal in an open or closed DE reflector. Burning position tolerance is +/-15 degrees from horizontal. Pair with the Growlite HDE Reflector for even PAR output across a 4x4 to 5x5 ft canopy. Warm-up to 90 percent runs about 4 minutes. Hot restart takes 3 to 5 minutes. That timing helps when scheduling lights-out events without overlapping bloom photoperiods on shared circuits. The K12x30s base, 32mm bulb diameter, and 197mm light-center length match standard DE sockets in commercial flower rooms. The 5KVA socket pulse rating handles ignition cleanly without socket arcing under load. Max base temperature is 250 degrees C and max bulb temperature is 700 degrees C. A digital ballast keeps double ended HPS PAR output consistent through the 20,000 hour rated lamp life. Photoperiod planning matters in commercial flower rooms running staggered cycles. The 3 to 5 minute hot restart leaves room for brief power blips without losing the lights-on schedule. Even PAR distribution across the canopy depends on reflector geometry and lamp orientation, both standard for this T10 envelope. Key Features Watts and Voltage: 1000W at 250V and 4.7A operating current through a T10 double-ended envelope. PPF Output: Approximately 2000 µmol/s PPF in the 400-700nm range for canopy-level flower intensity. Lumen Output and Efficacy: 140,000 initial lumens at 140 lm/W keeps photometric output high across the cycle. Spectrum and Growth Phase: 2000K Real Red profile sits in the Flowering / Bloom range for finish-stage HPS rooms. Rated Life: 20,000 hours of rated life supports multi-cycle commercial bloom-room rotations. Bulb Format: T10 double-ended bulb with K12x30s base fits standard DE reflectors and ballasts. Warm-Up and Hot Restart: 4 minutes to 90 percent output; 3-5 minute hot restart for scheduling reliability. ANSI S52 Designation: Pairs with electronic DE ballasts including the Growlite HDE Switchable.
