Shiva, a few suggestions ; make sure lamp is installed correctly, anode side down, anode/ cathode connections nice n tight at the light source n power supply, over cooling ??? Turn cooling off n turn lamp on, for a 500W lamp the normal operating voltage should be around average of 60vdc and 8.5 amps, last but not least .. A bad batch of lamps ??? I have seen this a few times thru the years...<div><br></div><div>I hope this helps.....

<p class="MsoNormal">The lamp in the mask aligner is not reaching 500W its stays at 150W. I did send the power supply to EVG to test it in their unit and it works fine. I changed the bulbs and still the same issue. Does anyone had faced similar issue in your
Mask Aligner.</p>
