Greg, a word of warning. Any food placed to keep warm under such a lamp should be consumed within a reasonable period, say 30 minutes from cooking. Warm food can be a breeding ground for dangerous bacteria and a lamp should not be used for defrosting or heating stuff like butter for spreading,[though I guess you never have to do that often in Florida!]. The safe temperature for keeping food warm is 140F [60C] minimum.
BTW, if it gets too hot under a lamp you may damage the worktop, if it's laminate, by 'unsticking' the latex glue or bubbling the top transparent coating.
