Spectrum and application
DLI states that the spectrum is optimized for higher photosynthetic efficiency , with the red and blue parts boosted. This makes the lamp suitable for a full grow cycle , including intensive vegetation and flowering.
An additional commercial source indicates a color temperature of around 2000 K , which is typical of HPS lamps with a pronounced red-orange part of the spectrum.
Luminous efficiency
PPF: 2100 µmol/s
Efficiency: 2.06 µmol/J
Compatibility
The lamp is designed specifically for:
- DLI Joule Series
- most 1000 W Double-Ended HPS systems
- lighting fixtures with K12x30s holders.
It is important that the luminaire 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 life and maintaining high µmol output .
For professional cultivation systems, periodic replacement is important, as with HPS technologies, the light flux gradually decreases over time.
Dimensions
- Length: 394 mm
- Approximate width: about 38 mm
- Socket: K12x30s .
