iceap 660 and single reflector vs. wavepoint retro.
 

My Icecap 660 ballast got fried and I need to decide if I should scratch my current set-up and replace it with a Retrofit Wavepoint with individual reflectors and there ballast.

My current tank dimensions are in my signature. It is (or was until yesterday afternoon) currently lit with an Icecap 660 ballast and 4 T5 bulbs on SINLGE reflector.

opinions? how long can my sps go without light?

Is your current light a retrofit? If so, why not just buy good SLR reflectors (eg. icecap or sunlight supply) and replace your single reflector? Then you can choose to replace your icecap ballast or not, as you prefer?

I would not go more than 3 days without light for your corals. Thats even stretching it but I imagine they will be fine.
