Superior Technology from Metrolight 94% efficiency with Metrolight’s Smart Electronic Ballast for HID™ Micro-Start™ Ignition Process High Frequency Operation Dimming – Analog, Digital, Pre set Metrolight’s Smart Electronic Ballast for HID™ is an intelligent device built around a powerful microprocessor that enables: Monitoring of all internal ballast parameters Control of energy supply to lamp Connectivity to control and monitoring systems
5 © 2007 Metrolight Inc. All rights reserved. Core Challenges with Magnetic Ballasts Stressful Ignition Process Excessive amounts of energy and current are pushed during ignition process Damages lamp electrodes Creates arc chamber wall blackening Causes lumen degradation Dramatically reduces light output Low Frequency Operating Process HID lamp powered by low frequency sine wave that causes drastic electrode temperature changes Further erodes electrodes Shortens lamp life Creates bulb wall blackening Causes flickering
6 © 2007 Metrolight Inc. All rights reserved. MicroStart™ Ignition Patented technology – computer controlled digital ignition High frequency bursts Ignites lamp almost immediately Does not require high repetition rate of pulses Very little energy discharged (1% - 2% energy compared to magnetic) Immediately stops energy flow when ignition is detected by microprocessor Reverts to current-mode control ensuring lamp power-handling capability not exceeded
