Hi,
I am a Certified LabVIEW developer and can help you with this no problem. I am a Test Engineer working with LabVIEW over 6 years writing complex test automation programs for production line testing of electronic devices. If my bid is successful I can have a first draft VI for you to review within a day. Also - please advise the formulas you would like me to use for converting voltages to foot candle and lux.
Chat soon,
Shane.
