Heat. A failure of the ballast in base of the lamp could, emphasize could, cause insulation of the cord that is dangling by melt. It has happened. Shitty made in china extension cords can get brittle, crack, and shock someone that isn't being careful when they go to unplug or move the wire. The car frame might be grounded if your wheels have been stolen and the brake rotors are resting on the ground. Otherwise, nahh. Fuck the ground. Ground are for sissies.
Do you have any idea, any idea at all what Watts, Volts, and Amps are? NE?
Your laptop apparently wants or can draw as much as 3 Amps at 19 Volts which is 57 Watts of DC input. I have no idea what the efficiency of the power supply / battery charger is but lets assume it's 90%. That means your only putting 63.3 Watts into the power supply, assuming 90% efficiency. Add your two 20 Watt bulbs and you're still good to go. Shitty half assed setup, but it will be ok for a while.
Just because it's rated for 660 Watts doesn't mean you should use all of it. There's the issue of the lack of ground that can't be ignored either.
What a dumbfukc. In a 120V ac single phase circuit you have a hot and a neutral which is close to ground potential. If your fixture has a red wire in it, it was either wired by a fucking retarded african, or its on a 3 way switch. Ordinarily, the black is hot, the white is neutral and the green or bare conductor is ground. 240V branch circuits may or may not have a neutral depending on application. An electric heater for example will typically have 2 current carrying conductors black and white and both are hot. The bare wire or green is still a ground or non-current carrying conductor.
If you're bent on hooking up a fire hazard, by all means don't let anyone here try to stop you.
Yup, real classy african. Real classy.
