Ebay (Artemis) MH Bulbs

[christyf5]

For those of you running the ebay Artemis metal halides, how long are you running them for before replacing? Wattage and color temperature too please.

Currently I have the 10k 250w running, been in there about 3 months. I just switched out to some 14K that I had purchased sometime last year (or maybe the year before?) but only ran for 2 months before I decided I didn't like the color. I still like the 10k but am having some algae issues and it was suggested to try the higher kelvin bulbs.

Anyway, just wondering if these bulbs have a shorter life than the pricier brand names. I used to run my ushios for a year before changing them out (hello Boxing Day sales!) but nobody seems to sell them anymore so I thought I'd try ebay again.

Thanks!
