Today, a newly installed lamp fixture started fuming and before a fire started I quickly switched it off and had an electrician check that out. He found that the 160W lamp had melted the "heatproof" plastic material which was inches away. I was then told that the 160W lamp was 110V and not appropriate to be used here in China. Yes, I ordered these lamps from US and have been using them in Beijing China where I reside. The electrician said that used here in China (220V), that lamp would be twice as bright (producing twice as much heat I suppose then) and that that would also cause the lamp to have a shorter life. Is it true? The said 160W (110V) lamp is Zoo Med PowerSun UV self-ballasted mercury vapor lamp. One which I could not get an equivalent of here in China. Can someone tell me how I could use this lamp safely here in China? I really love this lamp for what it could do.
