BallaBooYeaH, you may be able to order it online, but shipping may put this simply out of reach cost-wise. However, I have to imagine if you contacted some lighting companies in your country and told them what you are looking for, they should have something comparable. 6500K, 5100K, and even the 2700K bulbs do work. The 5100K does it the best. I've only got two of them over my refugium and the cheato is growing like nuts. I was thinking I'd need to install four bulbs over that 29g refugium, but perhaps not.
Regarding T-5s, I know you have those in your area because Europe was using them well before the U.S. started to. Check those online vendors and your LFS for the different bulb colors. Basically, I like the look of a tank that uses 50% daylight(white) and 50% actinic (blue).
