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.

Purple PlusCombines the properties of a full spectrum bulb with strong red and blue components, producing a bulb with excellent color rendition that works very well to bring out pinks, purples and reds in an aquarium. Recommended in combination with at least two or more other T5 bulbs.

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, heres 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
