Frequently Asked Questions
Is it possible to calculate the lifetime based on the ULV 1000 19J datasheet?
The datasheet specifies the expected luminous flux degradation and LED lifetime; this serves as a guideline for the designer. In practical evaluation, operating temperatures and the dimming mode must be considered, so it is better to confirm lifetime calculations with field measurements.
Which FL 1500 parameters are critical for retail spaces?
The main parameters are luminous flux, luminous efficacy, light distribution, and CRI. They affect showcase brightness and the overall atmosphere. Luminous flux stability during long-term operation and compliance with datasheet tolerances are also important.
What should be done in case of discrepancy between datasheet and actual measurements?
The first step is a documented verification using a template: measuring flux, checking power supply and temperature. If the discrepancy is confirmed, a claim is filed based on the measurement results, and the data is sent to the supplier for coordinated adjustment or replacement.
What are the allowable luminous flux tolerances under GOST for ULV 1000 and FL 1500?
According to industrial standards (including GOST R and IEC), the allowable deviation of the luminous flux from the nominal datasheet value is no more than ±10% during the initial operating period under nominal temperature conditions.
