Anyone used "Pure'' brand P/C bulbs?

Has anyone used the 'pure' brand Power compact lights before?
Pure Aquatic 10000K Compact Fluorescent Lamps - Square Pin | Compact Fluorescent Square Pin Bulbs | Bulbs & Lamps | Aquarium - ThatPetPlace.com

I only need one replacement bulb ( other is a coralife one) .. this one is quite a bit cheaper.. they seem like decent quality, but I didnt want to buy it if it was 'junk' compaired to the coralife one. I know i'm hestitant to use any other brand of Metal halide, too..

any suggestions on good quality bulbs as well as comments on these brands would be really helpful!

Thanks
