2.3 Ma<strong>in</strong>s behaviour<br />
The absolute ma<strong>in</strong>s voltage range is specified as shown be<strong>low</strong>. If the ma<strong>in</strong>s voltage is too <strong>low</strong>, the gear will dim the<br />
lamp to 50% power so as to protect it aga<strong>in</strong>st too high an <strong>in</strong>put current. If the ma<strong>in</strong>s voltage drops be<strong>low</strong> the<br />
m<strong>in</strong>imum, the gear will shut down the lamp.<br />
This behaviour is represented <strong>in</strong> Figure 4:<br />
