Can I get an LED light installed into my incandescent downlight cans?

Yes, absolutely. As long as the LED bulb and incandescent bulb have the same base they will both fit the socket. The LED bulb will also run much cooler than the original incandescent bulb.


If you have brighter bulbs will the battery last longer or will it run down quickly?

That does not depend directly on the brightness of the bulb, it depends on the current drawn by the bulb (which depends on the efficiency of the bulb). For example an incandescent bulb will draw much more current than a much brighter CFL bulb or LED bulb. Therefor switching to an brighter LED bulb can make the battery last much longer while switching to a brighter incandescent bulb will make the battery run down quicker.

Can i use a 60w led instead of a 60w incandescent bulb in an outside post lamp?

You could but it would be extremely bright! An incandescent lamp of 60 watt is about 800 lumens And so a 10 watt LED lamp should be plenty big enough. If you want as much light as possible instead of energy saving then you can fit bigger wattage LED lamps. Also, because they run a lot cooler, you can often exceed the maximum (Incandescent) rating for the fitting.
