I am able to power on my LED unit here with a 9V battery. I'm using a recharble lithium 9V as well.
I can't figure out why I can't get blue, purple, and white. The only colors I get are red, orange, yellow, and green.
The LED panel is normally used for some lights in a car, 12V DC, but I know that 9V can power everything at a lower brightness.
Any ideas what is going on? I can't change power sources because the mod goes into a collectible figure that only has room for a 9V sized battery.
