If you are using an incandescent bulb, yes, as the shade is glass.
No...it takes only a 60 watt bulb. I am 84 and need a good light and, for whatever reason, this is as bright as a 75 watt...the inside is white...that may explain it.
It also uses those wiggle bulbs which say they last for years but don't. I never buy them anymore but am hoarding the good old, 60 watters, now that I have this really excellent lamp.
Not at all. Mine stays cool all evening.
