Yes and no for easy, pretty easy. There are just 2 wires, and you have to fiddle with the housing to get it lose.
There are 4 pieces of thin aluminium that hold the lamp in place.
Whether or not the lamp is faulty is not obvious, but there are two key signs that will sometimes happen...
1) After about 800 hours or so you will see a sudden MASSIVE drop in brightness
2) The projector may give a lamp light warning, even though the lamp still works if you turn the PJ on and off
My recommendation is not to run the lamp over 2000 hours to be safe, since they are so cheap to replace.
Also, just because I had some lamps explode, does not mean you will. I have't seen all that many people have exploding lamps on the RS-45.
To Change the Lamp
The wires are screwed on, but I find it is easier to just screw one wire, and solder the other. You may find it easier to just screw both wires on.
There is an easy soldering point you can use that already has a bowled shape of solder on it, I don't re-use it, I simply apply my own solder to attach to the existing solder. That way I don't have to get everything quite as hot.
It generally takes me 45 - 60 minutes to change the lamp, and that includes soldering time.
If you mess up the housing, it's not that big of a deal, you can buy the housing as well.
