Why does BRS recommend this?
The Blue Plus bulb is by the hottest selling T5 bulb available, for its crisp blue, that brings out awesome coloration in corals. : ATI has been some of the most sought-after bulbs in the reef aquarium hobby. With their bright crisp colors, ATI are our number one choice when it comes to T5 bulbs. With ATI bulbs you can use a single color on its own or you can mix and match to make the ultimate spectrum.
The ATI Blue Plus T5 HO fluorescent bulb combines the properties of a blue bulb with a True Actinic Blue 03 bulb. Encourages bluing in SPS corals and fluorescence in capable corals. Helps balance out a washed out or yellow hued tank. Works well as a supplement to metal halides or in combination with a 6500K ATI Sun Pro or an ATI AquaBlue Special.

Tested trusted quality product By curtis on 5/10/2018
curtis would recommend this product to a friendI thought all actinic bulbs were created equal long story short i was wrong there is something different about the spectrum of these bulbs from a company like ATI side by side with other generic brand actinic bulbs I see the difference and so do my corals and p.s. super affordable thanks to BRS -
Can’t beat it By Lucas on 4/9/2018
Lucas would recommend this product to a friendUsed in combo with the ATI Auquablue special this is IMO the best lighting option. I use these in a coralife fixture and when I first went from the coralife bulbs to the ATI bulbs I could not believe the difference visually and the improvements it made on my livestock. I wouldn’t ever switch bulbs -

Blues!!! By ReefPammy on 3/8/2018
ReefPammy would recommend this product to a friendBurned in over 50 hours, and still so much more "WOW" than (Odyssea actinic) bulb it replaced. My teenager actually blurted out, "Wow!! Tank looks so Great!!! Really Blue!!". before realizing that--teens are not supposed to compliment their parents' tanks...
Very bright, crisp, blue; teased colors from our corals we had previously only seen from Kessils. Beautiful polyp response from everything in the tank, from moment one!!! Super fast shipping, and meticulously packed. From my teenager and me -

Product desc. says 48 inch ? Is this a 45 inch bulb for a 48 inch fixture?

Great question!
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!

The bulbs don't say HO on them. Are they rated that for HO fixtures? Thanks.
Question posted on Nov 23, 2016 5:54:00 PM
Great question! These bulbs are T5 HO bulbs. The ATI Blue Plus T5 HO fluorescent bulb combines the properties of a blue bulb with a True Actinic Blue 03 bulb. BRS Note: The ATI Blue Plus T5 HO fluorescent bulb is one of the most popular actinic bulbs available. :-)

How long do ATI T5 bulbs last if unused? For instance, if I buy a couple extras and don’t use them, can I swap them in 10-11 months later and have them be as good as new? Or should I buy “fresh” bulbs?
Question posted on Nov 25, 2017 3:41:00 AM
The lights, if unused will last almost indefinitely. The only thing that will degrade their lifespan is actually using them. : )

What is the par rating on a 36" blue plus
Question posted on Jun 5, 2016 8:05:00 PM
Great question!
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.

I have a 75 gal aquarium and a T5 6 bulb fixture that I picked up for a good price. I am going to set it up and move my anemone and clown fish over to it and maybe add a few soft corals and maybe a few lps corals. was wondering what would be the best combination of t5 bulbs would work the best?
Question posted on Apr 3, 2016 2:39:00 PM
Great question!
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!

I have 2 48" blue plus in a reefbrite supra fixture. Donyou have a general idea of what the par reading range would be around 8" off the water?
Question posted on Feb 19, 2017 4:51:00 PM
Hey there!
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. :-)
