The Dimlux Expert Series 1000W MKII DE EL UHF DXO represents the ultimate evolution in high-performance 400V HPS lighting. This new MKII generation includes the Ultra Optics 98 reflector and the DXO HPS 400V 1000/1250W DE EL bulb, specifically engineered to operate in boost mode without premature PAR degradation.
This system outperforms any standard 1000W fixture on the market and even many 1250W DE fixtures, setting a new professional benchmark in PAR output stability and light maintenance.
With a PPF of up to 2558 μmol/s at 1200W and 95% PAR maintenance after 10,000 hours, this fixture is built for commercial horticulturists seeking maximum production during the flowering phase.

The Dimlux Xtreme Output (DXO) HPS 400V 1000/1250W DE EL bulb:
✔ Specifically designed for dimming and boosting
✔ Maintains PAR even above 1000W
✔ 95% PAR maintenance after 10,000 hours
✔ Red/orange optimized spectrum for heavy flowering
✔ Sufficient blue output for vegetative growth
Unlike standard bulbs that degrade rapidly above 900W, the DXO is engineered to operate between 1150W and 1250W without performance loss.
The DXO is a single-spectrum bulb highly focused on the orange/red range (intense flowering), with complementary blue output.
High output in the 600–680nm range
Excellent canopy penetration
Ideal for maximizing final weight and flower density
Designed under the Single Bounce Clear Sight (SBCS) principle:
✔ Every photon reflects only once
✔ Higher light efficiency
✔ Lower operating temperature
✔ Extended lamp lifespan
✔ Reduced cooling costs
Includes a 50mm top connection for active or passive heat extraction.
