T5 bulbs -- ATI and Giesemann

[Kirk_M]

Is there any difference at all between the following T5 bulbs, or are they just manufactured by the same company and relabeled by these two companies?

ATI BluePlus and Giesemann (D&D) Actinic+ (I AM NOT TALKING ABOUT PURE ACTINIC BULBS HERE! - the combo blue/actinic ones)

ATI Aquablue Special and Giesemann (D&D) Aquablue

Many thanks,

Kirk

I think the ATI ones put out more light but im not sure, tagging along though as its getting close to time for new bulbs for me :)

Greg at reefgeek told me that the ATIs are a 2nd generation bulb and has a higher output. He said that previously, they were the same bulbs though, until the two companies broke their partnership.

im running all Giesemann right now, got the bulbs when i got the retro kit 6+ mo ago.
running 4x54 2actinic+ and 2aquablues. I get great growth and decent color with them over a 55. Its very chrisp white.

When i reorder bulbs im going to try out the ati's for sure.

I like the ATI blue+ over the Gieseman's blue+.

The ATI is brighter IMO.
