I picked this adapter up to power my Flashpoint 312 LED light but I don't know how to decide which tip and settings to use. The light has DC7.4~14.8V written next to the power port. Also, the light & adapter polarities look a bit different. Would you be able to help?
I can't totally answer the question, as I was never sure I found the right settings. The combination that seemed to make the light work best resulted in the adapter getting so hot it melted the paint on the surface it was laying on. It could have been a fire hazard had it been in contact with something besides a painted drywall windowseat. After that I stopped using it and bought a different adapter, which worked fine. (Should have returned the first one but never got around to doing that.) All I can say for sure is be careful how and where you use it. Sorry I can't answer with specific settings, but in the interest of safety I decided to pass this info on...
