DLI Horticulture Plus 1000W DE HPS Lamp – 2100 µmol/s double-ended HPS lamp for growth and flowering

DLI Horticulture Plus 1000W DE – HPS

DLI Horticulture Plus 1000W DE HPS is a professional double-ended HPS grow and bloom lamp, optimized for high photosynthetic efficiency. DLI developed the spectrum with enhanced red and blue components, and the lamp delivers PPF 2100 µmol/s at a power consumption of 1020 W and an efficacy of 2.06 µmol/J. It is designed for DLI Joule Series systems and is compatible with most 1000 W DE fixtures.

DLI Horticulture Plus 1000W DE HPS is designed for professional greenhouse and indoor lighting where high light output and stable operation are required. The manufacturer highlights its specially optimized spectrum and gas mixture, designed to support high µmol output and a long service life.

This is a Double-Ended (DE) lamp with a K12x30s base, which should not be confused with standard single-ended E40 HPS bulbs.

Spectrum and application

DLI states that the spectrum is optimized for higher photosynthetic efficiency, with the red and blue parts enhanced. This makes the lamp suitable for a full growing cycle, including intensive vegetative growth and flowering.

An additional retail source lists a color temperature of around 2000 K, which is characteristic of HPS lamps with a pronounced red-orange part of the spectrum.

 Luminous efficacy

PPF: 2100 µmol/s

Efficiency: 2.06 µmol/J

 Compatibility

The lamp is specially designed for:

• DLI Joule Series
• most 1000 W Double-Ended HPS systems
• fixtures with K12x30s holders.

It is important that the fixture and ballast are designed for 1000 W DE HPS lamps. It is not suitable as a direct replacement for a standard E40 HPS lamp.

 Service life

Lamp model with long average lifespan and high µmol output retention. 

For professional cultivation systems, periodic replacement is important, as light output gradually decreases over time with HPS technology.

 Dimensions

• Length:394 mm
• Approximate width: approximately 38 mm
• Base:K12x30s.
