I think you will be fine with the LEDs, I don't even know if I have any Incandescent bulbs left anymore. It was just a slight difference I noticed. Now, a bit older, these old eyes probably could not tell a difference.
I will add, when I first setup my CAMs, I was focused wrong in thinking I wanted 30 FPS, video production quality, but with the help of the great guys on this Forum I switched my thinking to that these are Security Cameras, not trying to make a movie out of the footages. I dropped my FPS to 15 and treated them as the cameras they are suppose to be, with the right settings. It made a huge difference in my playback videos...the key is to cap that crisp image/footage of the person of interest. People are not just standing around to give you that perfect shot, so in movement it is important to have the right settings. As @wittaj and others here preach, having a higher Res. won't give you a better cap in a moving object, especially at night. Hope I said that right
Select Manual to turn LEDs on, Off to shut them off (doh!).
This works only when the Night profile is running. The [1] subscript selects the Night profile. I use Manual to turn the lights on, but I guess Auto would work too. With manual it uses whatever brightness is set with the camera UI.
I have another camera using IR that overlaps the T180s FOV. BI is set up so when the other camera is triggered, it turns on the T180's lights, then turns them off after a minute.
