same problem here with one out of 3 dl-2 in a show. bulb is going off after aproxx one hour of not using the dl2 on a floor position (pan + tilt at 50%) Restrike is no problem. only 193 hours on the bulb. Show is now running for three days and every day after the dinerbreak the bulb is off. till now no problems during showtime.
gone test it next week in the shop with a new bulb. i'll keep you informed
Ok, i had some time this week and tested the dl2 in the shop. With the old lamp it still went off after aprox one hour. I've replaced it with a new bulb and now the problem is solved. I will contact Fons or Frank about how to get the bulb replaced under waranty
