UV-B & -C are downright nasty & can really hurt you as well as most any living thing.

That's an interesting article on UV! So in other words. 1. the uv shields on halide bulbs only block out some UV and by some I mean hardly any. 2. UV is harmful to corals.

I am no expert and have only ever had LED lights I took this picture today of my tank i have had this setup for 5 months and the lights are only at 60% intensity so far I started at 20% and gone up from there. This was a kit from RapidLed and a friend built for me there are 6 blue, 4 white, 1 red and one moonlight.

Sorry my IPhone 4 doesn't do justice but with the exception of one coral all my coral are thriving under this set up with full bloom and great colour. Almost all came from a MH tank and within days were doing great and are all growing at a fast rate. I wouldn't go with any other lighting setup because I am very impressed with how well the coral are thriving under the LED lighting.
