[GARY MINKER]

Hi The encasement in solid plastic is used as a heat sink. This is a common practice in multi killowatt transformers. It is done at high vacume to insure that all the air is expelled. --- On Tue, 1/6/09, freewill2008 wrote: From: freewill2008 Subject: [WanderlodgeForum] Re: GFI Faults and interior light replacemts To: WanderlodgeForum@yahoogroups.com Date: Tuesday, January 6, 2009, 1:40 AM --- In WanderlodgeForum@ yahoogroups. com, "timvasqz" wrote: > Bob, did they work before and now brighter and more efficient?

BG: They run dim in winter if the bus is cool inside. They warm up and get brighter after a few minutes. If all the fixures are the same brightness (or dimness) you may be seeing the effect of cold. They also run dim with old tubes and failing ballasts. I don't think the interior lights are designed to be "office bright".

BG: The orginal 12V solid state ballasts in my fixtures were encased in solid plastic. The designers were not worried about heat. Bob Griesel 'FC31 WLII WA
