KZ bulbs are just more expensive than ATI bulbs for (maybe) a little bit of advantage and hence people tends towards ATI. Both are German bulbs so no compromise in their quality

I run 2 kz coral light II gen And 2 kz super blues and they are nice lights. Nice colors and I had no problem growing corals. I'm going the other way from kz to ati bulbs. ($50 price difference). You will enjoy the kz bulbs for sure.

I've read the opposite of what Raied stated
ATI are the preferred bulbs, with KZ coming in a close second, and Geissman being possibly 3rd depending on what you read where
For me, the prices follow the trends above
I replaced all my ATIs with KZs as I can get them locally instead of ordering
I went from;
Blue Plus to Super Blue (close enough for me)
Fiji Pink to Fiji Purple (don't care)
Aquablue Special to Coral Light II new gen (from 15K to 14K)

All are minimal differences in spectrum

The Coral Light you mentioned is a 10K bulb and looks yellow to the eye, but is a very bright white in your tank and would be a good replacement for one of your gen II bulbs

If you're not growing show corals, or trying to make a living with them, you'll be fine with either brand

Just don't change all your bulbs at the same time
Do it over weeks per pair so your corals can adjust

If you want to compare spectrums, look on Reef Geek
I searched for 54w bulbs, but it's all the same

Here's a small fight about it :

Honestly, PARs cannot be compared between different people's value since ballast, reflector and the operating temperatures are variable. I tried finding the numbers but couldn't. Sanjay's reef lighting guide doesn't include T5. Don't know why he didn't look into it

For most, it's comparing apples to apples
Mine is more green than yours, but what shade of green are we talking about here ?

Like I said, for most of us, ATI and KZ are both good enough, and are the best around

Shades of green

Yah other than the price, one cannot go wrong with any of those two brands of bulbs.
