Ok, let's hear it!

Has anyone had any experience with Pacific Sun's LED/T5 combo fixtures (and knows of a dealer!)? I'm a big LED lighting fan, but I find the lighting so point source (especially with my Kessil) that shadows can become an issue. Adding T5 seems like a easy solution to that, but I'm not willing to spend over $1000 on the 24" ATI T5/LED fixture... just seems over priced.

I have! we subsequently dropped them from distribution. PM me if you want any further info but some previous end users may post their own experiences.

Good Day:

Here is an interesting article from Advanced Aquarist:

The light spectrum on the surface can be defined as a function I0(λ), where λ is the wavelength and I0 is the intensity for corresponding wavelength at zero depth. Hence the adsorption spectrum Ia(λ) at the depth D can be determined as
Ia(λ) = I0(λ) · K(λ) · D (1)

Does it say if I can grow SPS under LED?

When one cannot make someone believe something, starting putting complex equations.....and it works
