down from 530 watts to 440 watts...
Now we're talking about "pc power supply" range for $50 bucks, rather than
expensive $250+ DC/DC converters...
What do you folks think?
Has anyone used a cheap pc-power supply rather than a DC/DC converter - to
recharge their 12-volt aux battery?
Do you think it would hold up?

Around and around we go...
The one big plus for LED lighting is the possibility of using a
smaller/less expensive DC/DC converter.
Headlight on HI = 130W
Heater fan HI = 250W
Misc 12V = 60W
TOTAL SO FAR = 440W
4 marker lights = 5W x 4 = 20W
4 turn signals = 27W x 4 = 100W (intermittent - can use "peak power" from
DC/DC)
2 brake lights = 27W x 2 = 50W
2 tail lights = 5W x 2 = 10W
Center brake light = 5W = 2 = 10W
TOTAL LIGHTING = 90W/190W (intermittent)
So LEDs can reduce your DC/DC requirements from 530W to 450W.
