I tested a new to me Durst 601 CLS. The lamp intensity is 3 stops or more dimmer than my LPL 670 dichro. The lamp has a 1 sec delay when activated through a timer. The lamp has a slow start when turning on; you can see light intensity build over the sec it takes to fully turn on lamp. The Durst lamp is 12 volts, 100 watts, the recommended values. The domestic manufactured voltage stabilizer is 117v, 60 HZ, 1.3 A max. The lamp is in the proper position in the head. What is wrong?
