The average lifespan of a 60 watt halogen bulb is around 2,000 to 4,000 hours.
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.
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.
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, it will not be. You will need at least a 50 watt halogen for outdoor lighting.
It varies from about 600 to 1100 lumens. Typically the higher the lumens output, the shorter the lifespan of the globe. Have a look at this list of globes for purchase whih shows wattage and lumens: http://1000bulbs.com/category/75-watt-incandescent-standard-shape-light-bulbs/

Yes, you can use a 53-watt halogen bulb in a fixture rated for a maximum of 60 watts. Since the halogen bulb's wattage is below the fixture's limit, it should operate safely without overheating. However, it's always good practice to check the fixture's specifications and ensure proper ventilation.
Probably a 50 watt halogen
A halogen bulb works equally well with AC or DC.
