The bulbs are labeled by the size of fixture. As long as the wattage matches they will work for your fixture! Feel free to let us know if you have any further questions!
This will vary depending on height and other factors, what reflectors and other impact however under 6-10 inches of tank you can expect high par in the 200-300 range for good SPS growth. at 24" you can expect lower par in the 100 or lower range.
The best combination of bulbs through ATI that we use are the Blue Plus and the Aquablue Special. We typically recommend 2 of each on 6 bulbs. From there you can use the remaining slots for supplemental lighting such as coral plus for more white based light, actinic for a deep blue and purple plus for unique coral colors. Feel free to let us know if you have any further questions!
Although we wish we could test each bulb and fixture combination available on the market, unfortunately that isn't possible for us. Each fixture has minor variances in things like wattage and amperage draw. Because of these differences, their respective PAR readings can be different even with the same brand of bulb. :-)
BRS Note: The ATI Blue Plus T5 HO fluorescent bulb is one of the most popular actinic bulbs available.
Great Light By R. Mac on 2/8/2017R. Mac would recommend this product to a friendI have been using these bulbs for over 8 years. I get tons of growth on all of my corals.
Good morning light By Dr. Zoidburg on 10/28/2016Dr. Zoidburg would recommend this product to a friendI mixed this one with a Gieseman Super Actinic for morning lighting. Love the mixed color and the results.
Best of the Best By CorallineAlgae on 10/22/2016CorallineAlgae would recommend this product to a friendI started out using T12 & T8 bulbs about 20 years ago, then switched to VHOs, then power compacts and finally T5s. ATIs are the absolute best that I've used and the Blue+ is my favorite. I use the Blue+ to augment my LED fixture or paired with a Coral+ in a T5 only setup. These are the best you can get.

Unfortunately, one of my blue plus arrived broken, but overall, the rest look great!

Best blue bulb out there. By Mitch on 12/16/2015Mitch would recommend this product to a friendThis bulb will make colors pop. And it has impressive par, according to most fourms. I would like to see BRS test the par of all the lights they sell. ( hint, hint) This bulb comprises 50% of the bulbs in my setup.
