xm 20K

[DonW]

Got my first 20k bulbs today. All I've ever used is good old Ushio 10.
Almost painful, blue. Are these things going to mellow out a little.

I love the color that Tom's xm 20k bubs have, I would think they should burn in a little less blue. might take a few weeks..

They do burn in a little, and it takes a little while to get used to them. I can't stand looking at tanks that are 10k anymore.

Guess I should give them some time. I'm only running 2 bulbs so its not as bright as the 3 10k's. With the loss of par do you think its ok to run just two bulbs?

I have a 10k and a 14k. I cant stand the 10k either.

Yeah...My 20K XM's were quite blue when I had my 75gal, but as they burned in, it mellowed out some. It still remained quite blue but with having an acrylic blue background, I liked it alot

I started out with 10k then upgraded to a used system that had 20ks and when they got old i switched back to 10k (due to advice) and to be honest i really like the look of 20ks it really gives the water a crystal clear peacful setting. I think my next bulbs will be 20k.

I think my XM 10K's are too white as well and am planning on trying the 20K's. Wish the PAR numbers were a little higher though. I may swap ballasts too.

Sometimes you just have to deal with what you like, that is why we're in this hobby in the first place right?
I would think your corals might not grow as fast but they still should do fine IMO I don't know if that is true or not. All I can think of is the bright light that sun room tank had & when the sun was shining it looked as if he had no light at all, dam sun is bright, now after several feet of water maybe that isn't the same.
