We use the HOBO Dataloggers (Onset Corporation) and find them very useful not only for light intensity, but also for temperature and relative humidity.  They are inexpenive, can be set up for a range of collection intervals, store the data, and then can be downloaded for computer storage. 

Try Googling: Onset Dataloggers and you will find all their models.  We have used the Model HLI, which is a single purpose light meter/datalogger, but you might think about Model H08-004-02, which is an RH/Temp/Light Intensity multi-purpose data logger.

We would like to monitor light intensities in our greenhouse and have the data saved in a laptop.  Does anyone have a suggestion for an inexpensive radiometer that has data acquisition capability?
