Troubleshooting Two Lights Not Working on Doosan Light Tower from 2011-2012 Model

Question:

Hello everyone, we are experiencing issues with two lights not turning on in our late model Doosan light tower, which we believe is from around 2011-2012. Before conducting any tests, we replaced the capacitor to ensure the power supply is at 60Hz and approximately 120 volts. One set of lights just needs some attention. Can anyone provide guidance on where to begin troubleshooting this issue? Any help would be greatly appreciated. Thank you.

The choice of lighting system depends on your budget. Starting with a traditional bulb and ballast is the most budget-friendly option. However, if you frequently use lighting, it may be worth upgrading to LED lamps for better energy efficiency and longevity. Consider upgrading to LED lights for cost-effective and long-lasting lighting solutions.

Thank you for your input, @The Peej. It seems unlikely that they will be doing the LED upgrade anytime soon, but perhaps it's a possibility in the future. Despite being a great unit, the frustrating part is not being able to determine if the lights went out one by one or simultaneously. Do you think it would be a good idea to try swapping the bulbs initially to see if that resolves the issue?

Is there adequate voltage at the light fixture and what type of bulb is being used?

Currently, I have successfully diagnosed the tower lighting issue. All four bulbs are operational, and after rearranging the ballast/capacitor combinations, I managed to illuminate the other bulbs as well. I then tested and confirmed the functionality of both switches by adjusting the wiring. Presently, the top two bulbs are functioning correctly according to the corresponding switch. Upon checking the capacitance of the capacitors at the ballasts, I observed they were all within the correct range. It appears that a new set of ballasts and capacitors may be required. The ballasts in question have three wires connected to them. While seeking advice from 1000bulbs, it was suggested that a specific replacement would be suitable, but I prefer to seek confirmation from an expert. The question remains whether these ballasts can be wired with just three wires. For more information, refer to the following link: https://www.1000bulbs.com/product/89418/PLUSRITE-7243.html. Additionally, there is a PDF on that page containing detailed specifications that may provide further assistance.

As an experienced electrician, I would recommend considering using Mogul base LED "Corn lights" with a brightness of 5000 Kelvin or higher as a cost-effective and efficient lighting solution. By eliminating the need for capacitors and ballasts, you can save money and simplify your wiring connections. These LED bulbs are easy to find online and offer a wide input voltage range of 120-208-240and277 volts. With lower heat output, instant illumination, and a long lifespan, these bulbs offer better performance compared to traditional HID lights. Opting for LED "Corn lights" can lead to significant energy savings, making it a win-win solution for your lighting needs.
