Giesemann or Sunlight Supply?

[supermarvin76]

I am looking at setting up 4 T5s for a 30 gallon, (36") long. I am planning on building a hood, and mounting a retro kit. I was looking at this Sunlight Supply kit http://www.reefgeek.com/lighting/T5...ch__4x39W_Tek_2_T5_High-Output_Retrofit_Kit_w!_Bulbs_by_Sunlight_Supply from Reef Geek.

Then I found a Giesemann 2 bulb kit from Marine Depot. http://www.marinedepot.com/ps_ViewI...oduct~GL2733~idCategory~FILTRTRFT5~tab~0.html I think this kit times 2, with the bulbs would be about the same as the one from Reef Geek.

My question is which is better, and why?

Thanks.

I don't know which is better. There are more Sunlight reflectors out there and more testing have been done on those, so they are more of a known, quality product; Geismann makes quality bulbs, but I don't know how their reflectors perform at all.
