How do you test a microwave high voltage transformer? The problem is that an electrician trip charge (which usually includes 30 or 60 minutes of work) will most likely be $75-150 for about 5 minutes of work on each light fixture. Compared to standard metal halide lamps, METALARC PULSE START lamps reach 90 percent of full light output 30 percent faster and have a 60 percent shorter hot restrike time. When this point is reached, the lamp will exhibit cycling on and off characteristics. The ballast limits the current by increasing the energy for the lamp. Identify any leaky areas. They are a large part of the equation when using fluorescent lamps. High-pressure gases are contained in the arc tube of metal halide lamps. If the reading is infinite, then the ballast is good. How many lumens does a 175 watt metal halide put out? If your fluorescent lighting is displaying any of the signs below, it could be a symptom of a bad ballast: You can check the fuse with an ohm meter or test light, it is either good or bad, with a test light see if the light will burn on both sides of the fuse. Although this is a common symptom of when the fluorescent bulb itself is about to go bad, it could also be a result of a faulty ballast. Causes of Ballast Failure.
