It takes 1¼ amps on a 120 v supply, half that on a 240 v supply, so it is unlikely to blow a fuse. But the inrush current on switching it on might be 5 times that.
It's a halogen bulb
Yes, the halogen bulb would provide about 30% more brightness (lumens) for the same electric power rating. So 70 watt halogen is about equal to 90-100 watt incandescent.

A 20 watt incandesent bulb is dim. For a medium sized room you need 100 watts. A 20 watt halogen bulb is brighter but still quite dim. These are marketed as low-energy but they are not. For a medium sized room you need 80 watts. A 20 watt fluorescent bulb can light a medium sized room quite brightly. This is a genuine low energy bulb.
No. Only replace lamps in a fixture that the manufacturer of the fixture recommends. By installing larger than recommended lamps this could create a fire due to the increase of heat generated by the over size lamp.
Yes. It just won't be as bright.
Halogen bulbs are about 30% more efficient so a 70 watt halogen does the job.

Approximately 15 lumens per watt for halogen, so 300 lumens.
Yes, the halogen bulb would provide about 30% more brightness (lumens) for the same electric power rating. So 70 watt halogen is about equal to 90-100 watt incandescent.
No, it will not be. You will need at least a 50 watt halogen for outdoor lighting.

Probably a 50 watt halogen
A halogen bulb works equally well with AC or DC.
Should be about 850 lumens. The same brightness is produced by a 15 watt CFL.
A halogen bulb IS ITSELF a type of incandescent illumination source. A 40 Watt traditional incandescent bulb usually emits about 400 to 500 lumens while a halogen may emit close to twice that. So a 25 W halogen might give out as much light as ah older style 40 W bulb.
