Lighting Issue URGENT

Ok today i got my reef lighting and it was supposed to come with 3 10k bulbs and 3 03 bulbs.. However it came with 3 10k ultra-sunlight bulbs and 3 20k blue 450nm bulbs... Are 20k blue bulbs ok to use in reef tank? I havent heard of anyone using 20k blue bulbs at all. Please advise..

TIA,
James

The lights itself is catilina 20k 450nm blue bulbs.. Along with Catilina 10k ultra-sunlight bulbs.. The 20k 450nm bulbs seem extremely blue.. Actually they dont seem blue they are blue.... Now since I have returned from the LFS.. The sold me 2 Percula Clownfish along with 2 neat looking Condylactis that are white with purple tips... They said that they would do well in my tank.. The clowns I am not worried about however the Condi's I am When doing research on them it seems as though they are not really reef compatible... From what I read it says with caution.. Has anyone had luck with these in a reef??? I wouldnt really consider my tank a full blown reef as of yet... But it soon will be over time... I have enclosed a pic of my tank.. Please advise should I take the Condi's back tomorrow??? Or should it do ok.. I dont want it hurting anything else in the tank... The only thing that I have in the tank as of right now is a few hitchhiker crabs, 2 percula clownfish, 2 astrea snails, a pencil urchin, 2 Condylactis, and a mantis shrimp that I am currently trying to catch.. BTW this is a 55gal tank

I see now, it seems they are calling that one a 20,000K Blue bulb...hmm,,,do you have a link to their website?

I have a 7000K blue bulb that looks exactly the same in pictures as your 20,000K does..but it is a hamilton bulb...

Also, is this the new T-5 HO lighting fixture?

Well, Condy's hmmm, had a few, lost one of them to a PH, and the others I took back to the LFS because they are simply not suited for a reef aquarium...They require strong lighting and perfect conditions which is a plus, but, they tend to uproot themselves and float around stinging everything in their path... They are also not hosts for any anemone fish. They pack a powerful sting and are undesirable by Clowns of any nature...I personally have seen one instance of it, a Yellow Tail Damsel I had once,,, used to back up to one and fan its tail at it and back up into it once or twice, but I did not give it enugh time to make a home because I got rid of the anemones as well as the damsels...
