ATI T5 bulbs use the latest advances in phosphors (the stuff that makes the color) and manufacturing techniques to produce bulbs with higher output, better coloration, and more stability.

The #1 selling reef specialty T5 bulb line is trusted and used at every level of the aquarium industry; manufacturers, corals farmers, shop owners and everyday hobbyists.

 
True Actinic
Produces a violet-blue light that is designed to maximize fluorescence in capable corals and make livestock colors pop. Color spectrum peaks at 421nm. Usually just one per fixture is used to add additional fluorescence to the system. Recommended as a supplement to LEDs and metal halides and commonly used for sunrise and sunset applications in T5 set ups.

Choosing the right bulb combinations for over your tank can seem like a daunting task. It can be hard to visualize just how each sequence of bulbs will look like in your fixture. While some parts of choosing your bulb colors is personal preference, here’s a general guide to help you select bulbs for your 4 bulb fixture:

16K – 20K – Bluish white with a noticeable blue and red under-tone
3 ATI Blue Plus
1 ATI Purple Plus

12K – 16K – Cool white with a noticeable blue and red under-tone
2 ATI Blue Plus
2 ATI Coral Plus

10K – 14K – Crisp white with just a hint of blue
2 ATI Blue Plus
1 ATI Aquablue Special
1 ATI Purple Plus

For aquariums with a lot of LPS corals, a True Actinic bulb can be used in place of Purple Plus to provide enhanced pop in coral color.
