Dear All, I apologize for starting this confusion. I should certainly know better, but give myself the excuse of too much travel, too little sleep and the sudden onset of heat and humidity. If I can have some defense it is that in re reading the messages most of them do not name the bulb in question except in the heading, not when referring to it in the body of the text except as 'it". When two very different bulbs are in the subject line, confusion seems likely. Of course this is something I am likely to do myself. Apologies. Jim W. -- Dr. James W. Waddick 8871 NW Brostrom Rd.
