Is This A Dangerous Upgrade?

I have 50/50 PC lighting on my tank if we go into wpg I am at 3.6. My tank is 20-23" deep and I want to begin keeping LPS. I was going to dedicate my one fixture to deeper actinic bulbs and I came across this_

I have heard that some corals burn under UV and I don't know if that purple will be good or bad, should I just stick with blue actinic ?

Oh, that's just a dual actinic bulb. Wouldn't hurt anything.
