Hello, I own the AA-385897-1 type of is lamp and face endless problems. First, I had to change the converter which an electric test showed it was not stable. The fact is it provided an uncertain light, sometimes fainting, sometimes inexistant. I changed the converter, it worked for months, than stopped. The new converter was tested and found out of order, the lamp being good. I bought a new one : it doesn't work. I am despairing because I like this lamp. Can you help me ? Kind regards JPLF
