Final assessment · 4 questions

No completed attempts on this device.

1. A complete luminaire produces 4200 lm from 32 W mains input. What may be claimed?
2. A 40 W driver has 25–40 V compliance and the module needs 38–44 V across conditions. Is it compatible?
3. A non-maintained emergency luminaire senses only the building incomer, while its local normal-lighting MCB can fail independently. What is wrong?
4. A design meets average lux but fails minimum uniformity and glare, while its emergency fittings pass only a dashboard self-test. Is it complete?
