Hi all,
So I'm really wanting to get a PAR meter and was looking at the apogee usb ones, but I run only LED's so I was wondering if the extra $100+ for the SQ-520 is worth it over the SQ-420. I have seen reviews where they say the margin of error isn't that much different or there is a correction equation can that be used. Does anyone have experience with the SQ-420 on LED's?
Thanks all!
