Those 2 LEDS you listed will not be able to support much in the way of light intensive corals or clams.
If your looking at LEDs I highly suggest looking into Kessil LED
fixtures. With the A350 model you will be able to keep any coral, nem or clam. The A150 model will do the same, however is less powerful and does not come with the dimming options of the A350. Here is a link to both. Also, remember you get what you pay for.
A150 Price $265
A350 Price $399
