Description
A Proven 1000W Double-Ended Lamp For Serious Light Output
The Philips Master GreenPower 1000W EL is a double-ended, 400V high-pressure sodium lamp built for growers who need high output from a single fixture. Its double-ended design spreads light more evenly along the tube than a single-ended lamp of the same wattage, and it is built to run at full 400V ballast output without an early drop-off in performance through the cycle.
Key Benefits
- 1000W double-ended (EL/DE) construction for high output from one lamp
- 400V operation matched to standard 1000W DE digital and magnetic ballasts
- Rated output around 2100 µmol/s, suited to larger rooms and taller canopies
- Even light spread along the tube compared with a single-ended lamp
- Stable spectrum through the working life of the lamp, backed by Philips' manufacturing standards
Getting Consistent Output From A High-Wattage Fixture
A high-wattage HPS lamp is only as good as the fixture and ballast running it — mismatched or worn components lose output long before the lamp itself is due for replacement. Using a lamp built specifically for 400V double-ended operation, matched to a compatible reflector and ballast, keeps output consistent and avoids the gradual dimming that comes from running a lamp outside its rated spec.
How to Use
Fit the lamp into a 1000W double-ended fixture rated for 400V operation, making sure the ballast is matched to 1000W DE output before switching on. Hang the fixture at the correct distance for your coverage area and canopy height, and allow the lamp to complete its full warm-up cycle before making height adjustments, as output and colour temperature settle after the first few minutes of each run.
