The problem with an inverter is that they eat a lot of battery power in the process of turning 12VDC into 110VAC. This means that the usable time of battery will be reduced. The better plan would be to go with straight 12 VDC lights.
Sorry to hear about the stool jumping out from under you. Hope yer OK.
I'll relay this to DH since he understands wiring. Me trying to figure stuff out doesn't always work. I dont touch electric stuff usually, have a little phobia that I cant break.
We have these under the counter battery opperated, led light bars that would work great out there if they just have more battery. I should get him to wire those into the panel and battery.
As for my injuries, nothing to bad. Few bruises and sprains. Sadly I'm used to it. I'm a bad klutz. Have been asked at ER if my DH beats me. That was the time I removed the membrane on my eye with a paper bag. DH came home from work and had to take me in on that one.
