The Dimlux DXO California Spec HPS 400V 1000/1250W DE EL is a high-performance double-ended horticultural lamp developed for professional 400V electronic lighting systems. Designed specifically for both dimming and boost operation, it delivers exceptionally high photon output and efficacy at elevated power levels.

When used with the Dimlux Expert 1000/1250W MKII fixture, the California Spec lamp is designed to meet the minimum horticultural lighting efficacy requirement of 2.1 µmol/J referenced in the 2022/2023 California Energy Code for larger indoor cultivation facilities. :chatgpt-content-reference{index="0"}

Designed for Dimming & Boosting

The DXO California Spec lamp is engineered for high-frequency electronic ballasts and supports a dimming range from 600W to 1250W. It is optimised to maintain very strong PAR performance when boosted above its nominal 1000W operating level. :chatgpt-content-reference{index="1"}

High Photon Output

At 1250W, the lamp produces 2780 µmol/s within the 400–700 nm PAR range and 3070 µmol/s across the broader 350–800 nm range. Photon efficacy reaches 2.23 µmol/J within PAR and 2.46 µmol/J across the wider 350–800 nm range at 1150–1250W. :chatgpt-content-reference{index="2"}

Flowering-Focused Spectrum

The spectrum is concentrated primarily in the orange and red regions to support flowering and fruit development, while still providing some blue output for vegetative growth. The lamp also produces a substantial far-red component, with Dimlux specifying a red-to-far-red ratio of approximately 6:1. :chatgpt-content-reference{index="3"}

Long-Term PAR Maintenance

The DXO California Spec is designed for extended horticultural use, with Dimlux specifying approximately 95% PAR maintenance after 10,000 operating hours. :chatgpt-content-reference{index="4"}
