If so, and you have too many requests for the new filter stack, I can just use what you sent. But IF you have any extras after that, I'd appreciate if you could send me a new stack. Just in case I can't make it to the Rosco dealer in Knoxville .. which is about 70-100 miles away.
Yes, you have it right - but one big difference between the two filter stacks is that the stack of 6 you have makes the meter read PAR directly, while the new stack makes it read 10X PAR, so if you use the 20,000 lux scale, it reads PAR directly, and more accurately. I mailed you a set of the 4 new ones.
