I haven't heard of any lamps exploding. The old(er) solvent-based glitter lamps are highly toxic if opened/broken though.
I think you're safe in getting those lamps.
I have several generic lamps of all kinds, i have yet to have any issues at all, no crack, breaks, explosions. The only issue I have had is bad flow.
Just don't put a capped one on the stove or in the microware and you should be fine ;)
