Have MH Ushio Question

[cybertec69]

Hi, I just received 2 new 250W double end Ushio 10,000k from Marine Depot, they are both stamped 10,000k but for some reason one of them is burning with a blue hue, like a 14,000k bulb, I spoke to someone at MD and was told to run them for a week and it should change it's color spectrum, if not just call them back and they will send me a new one, has this happened to any one else in here, and did it change color, thanks in advance.

be thankful, I run 10k Ushio DE's and they're YELLOW. Maybe you'll get lucky and they'll stay blue =)

My bulbs are up for replacement soon and I can't wait.

Most Ushio DE 250W 10K are white on M80 ballast. Try running it for at least 100 hours.

True, it will change once it burns in.

I had a similar problem with some xm 10ks. marine depot told me the same thing................I ended up with a new bulb

the thing is, my tank looks funny, white on one side, and bluish on the other side.

I just put a Ushio 14k in one of my pendants. Even after a few days, the color was so yellow, more like a 5500k bulb. This morning, I took it out and flipped it over. Color is now a crisp white with a hint of blue. Try flipping, it may work for you.
