RSM 250 bulb choice: Giesemann or ATI?

[davidcalgary29]

I need to replace the bulbs in my new/used 250C. The vendor gave me four bulbs (three of them Fluval "Power Spectrum" 18k bulbs). I've already put one in and am torn between the rest: should I go with ATI or Giesemann? I suppose the dilemma is a bit silly, as I'm only going to be putting a few softies and LPS in the tank.

Ati blu+ & coral plus

I did go with ATI Coral Plus! I also decided to try some Geisemann Aquablue Coral, as they were available from one supplier, and I've heard that they're quality bulbs.
