We purchased 5 sets of String lights church just prior

Customer Question

We purchased 5 sets of String lights for our church just prior to Christmas. The 5 strings are LED lamps each with a power supply output of 31voltsDC. Each power unit has 8 programs. When switched on the lights revert to the No1 programme which is flashing. We, however, only want the permanent on programme. As the lights are not left on in the church when closed and the power units are not easy to get to. I am looking for a simple remedy. I have tried to power the lights from a direct 30volt DC supply and every other lamp lights. If I reversed the DC supply, the other alternate lamps light. Is there a simple answer to this problem? We would be most grateful for assistance bearing in mind we don’t have any electronic knowledge.

Sorry, it is not exactly clear the question your asking.
"We, however, only want the permanent on programme"
Do you mean you only want it to go to one specific program when turned on?

Would it be simple to build a supply unit that only gives an 30volt DC output to keep the lights on permanent
Expert:  Richard replied 2 years ago.
The power unit does not drive the program of te lights, it is a microprocessor.
But I am still not clear, you want it to only choose one of the eight programs?
Customer: replied 2 years ago.
thats correct just the one program

Sorry I think I am wasting my time here thanks anyway bye

You cannot, as its not controlled by the power supply, but by a micro controller on the lights.
Most are provided with a remote control, it is very rare when it is not.
Have you checked if there is a remote for this? If not, can you tell me the make and model of the lights?
