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
