Tim (timfish) came by today and did some PAR readings on my new LED setup...
I took PAR readings of the t-5s that I had in my tank back in December... The results were about 120 in the center on the bottom of the tank with 10 48" 54w t-5s and around 400 at the water level. That was with 540Watts of t-5 lighting...
With 200w of LED lighting I am getting the following:
Blues only:
LEDs are about 10" from water surface
100 at surface
55 8" under
45 10" under
40 14" under
40 bottom of tank 24" under...
Whites only:
170 at surface
70 10" under
50 12" under
50 bottom 24" under
ALL lights at 100%
300 at surface
120 10" under
110 14" under
100 bottom 24"under
Take about 10 points off of each number on the edges of the tank otherwise the lighting is very even.
Thanks Tim!
