So, my grande had a over heating problem and would only last maybe 3-4 hrs. after it starts to flow well. I bought a dimmer that it plugs into the outlet and then you plug the lamp into it. Since then, I have been fiddeling around with the slider to find the best mark for it. I have finally found the spot and it is intoxicating! I could literally have it running 24-7 without over heating and it is hard to stop watching it! LOL I can sit and stare at it, watching the awesome movement of the flow and what seems to be only a few minutes is actually like an hour! My God! I have have to stop looking at it but it is like a little devil that says "it is ok, it is heaven, you can stare at me all day". Why is the grande the only China made lamp that remotely flows like the American lamps? Then on top of it you have the amazing size of it that glows like you have found the holy grail. It makes me want to just collect the grande lamps and stop collecting the smaller ones. well, not untill I can get my hands on an aladin or a saturna lamp. Anyway, something has to break this spell that this lamp has on me. anyone else have a stareing problem with the grande?
