hi all, thanks to those who responded to my request for information about field light meters.
here is a summary of those responses. 1) IMO, one of the best companies out there for measuring UV light is https://www.solarmeter.com/ <https://www.solarmeter.com/>. Not sure if this is exactly what you are trying to find, but they have many different models. I use one of their products to measure UV light coming from UV light emitting light bulbs used in keeping reptiles (they were recommended to me by a veterinarian). Also had a student use one of their products to measure outdoor UV light of where reptiles were basking. Their units are not cheap, but they appear to be of good quality and mine have last for several years with no problems. 2) LICOR has sesors for 'global radiation'. Don’t remember what is the spectral response, but they have excellent reputation. http://www.licor.com/env/products/light/ <http://www.licor.com/env/products/light/> 3) Are you looking for a spectrometer? In the past we've used and Ocean Optics Jaz spectrometer to get readings from 300 to 700 nm. However, since it is module, I believe you can customize which modules you need. They worked really well us and customized it to our exact needings. My favorite part about it was you didn't need a computer and could take it in the field very easily. You can find more information here: http://oceanoptics.com/product-category/jaz-series/ <http://oceanoptics.com/product-category/jaz-series/> 4) Boxcar (HOBOs) have a light intensity setting, you can ask them about IR thought -- we use these to meter moonlight when trapping moths at night. Very effective. td ------------------------------------------------------------------------- Anthony I.
