Preferred spectrum for clams?

[reefsrus]

What type of kelvin do clams do best under.. of course we all know sps do best under 6500k, and LPS do best under 20k light. But what about clams?

Generalizations should be avoided when it comes to reef animals. Tridacnids occur in different reef enivironments- some extremely shallow and some in deeper water.
Intense 6500k-10kk lighting would be best for crocea and maxima. Squamosa, derasa and gigas all occur in deeper water and seem to tolerate higher kelvin halides better than crocea and maxima.

Would a 14k bulb with the same PAR as a 10k bulb be fine IYO?

I try to avoid opinions.
Let's just say it can work. I keep a crocea under a 250w 14kk Hamilton.

I keep maxs and croceas under a 14AC and a Phoenix as well...but then agen the tank is only like 13inches deep.......
