Frequently Asked Questions
How should the designation ULV 1000 56 J FL=1500 be interpreted during selection?
Explanation: This designation combines the model and reference parameters: ULV 1000 indicates the fixture type and nominal flux, while the subsequent numbers refer to specific photoelectric characteristics. It is recommended to verify these designations against photometric tables and perform measurements under real-world conditions before procurement.
Which fixture offers better energy efficiency: FL 1500 or ULV 1000?
Answer: Under average conditions, the ULV 1000 often exhibits higher Lm/W at a stable temperature; however, the FL 1500 can deliver more light in high-mounting height applications. The specific choice depends on the required lux levels and operating mode.
Which parameters must be checked before purchase?
Recommendation: Verify datasheet Lm, Lm/W, CRI, degradation curves (L70/L90), IP rating, and warranty terms. These data enable predicting real-world efficiency and calculating TCO for an informed decision.
What are the typical luminous flux degradation indicators (L70/L90) for these models?
Tests show that the ULV 1000 model maintains up to 90% of its luminous flux (L90) for 72,000 hours due to improved heat dissipation, while the FL 1500 reaches the L90 threshold at approximately 50,000 hours under harsh operating conditions.
