Im going to be ordering a couple of 20K Xm bulbs from hellolights. Does anyone here use these lights and can I look at the color b4 I buy them? If anyone is using the 10Ks I will be really interested in lookin at that color as well.
Thanks

I recently had to replace one of my 2 no name bulbs that just sort of kept turning on and off at random. I decided 1st to try the XM 10k. When I recieved the 10k bulb it was much more yellow than my 14k bulb is. So I sent it back and recieved a 20k instead. Its much more blue than my 14k bulb but I can live with the white/blue, I couldn't live with the white/yellow. Your welcome to come by and see. I live in Pleasant Grove. PM me if your interested. I wish I could find a bulb that was reliable and had the cheep/white characteristics like my last bulb was.

I have ushio 10k MH 250watt that are supplement with pc actinics that I prefer over the 20k MH look. I like the crisp white look, but the 20k really make the corals really glow. Its all personal preference, your welcome to see mine I live by little cottonwood canyon just PM me if interested.

Asad...I am currently using an a 175W xm bulb for my 20g....it gives off a great deep blue and it inhibats the growth of most of you surf algaes. I posted some pictures of my new setup in the general post...."the new 20g" that is the color without any photo altering. if you like....I have plenty of pictures...plus I have seen all my corals open more than ever under just this bulb compared to the old 55g tank that has 10K(96wPC)7.7k(96wPC) and the xm 2kk(175WMH)

Great input guys. I think Ill be going with the 20K bulbs and not suppliment with actinics. Ill also have a 400W Iwasaki 6500 K to kinda balance out the light to a more whiter color.
