I normaly run Ushio 250 HQI Metal Halides 10,000k
I bought new bulbs because the old bulbs were starting to cause cyano growth and started to shift spectrum
When I ordered a new bulb I thought I ordered a Ushio but recieved a Hamilton 10,000k
When I installed the bulb it started up a yellow color. (Which is normal) But for the last 7 hours i'v been letting it run and it's stayed yellow, and hasn't shifted spectrums to a more white color like the old Ushio's..
Half my tank is white and half is yellow now.
Has anyone else had this problem?

First off, the Ushios are more expensive than the Hamiltons. I don't what you paid per bulb ( around $100 maybe ? ) but it usually take awhile for the color to burn in, 50 to 100 hours I believe. I like the Hamilton 14ks, I think they are very good blue tinged color bulb for the price, usually around $60 per bulb. It could be an honest mistake but I would inform the vendor of the problem.

I am currently running hamilton 10k's and even w/ my 330W of VHO actinics on, the water color is a bit too yellow. I am definitely going to switch to Ushio 14k's once these hamilton 10k's wear out in about 9 months.
