ATI T5 54w 4ft

MINIMUM ORDER 4 BULBS

Shipping T5 bulbs requires careful handling, and while we pack securely, transit damage can occur. Please note: we cannot replace or refund bulbs damaged in shipping—this purchase is at your own risk. If you prefer to avoid this risk, we recommend reconsidering your order.

Choosing the right T5 bulb combination transforms your tank's appearance. While personal preference plays a role, our guide helps you select the perfect mix for a 6-bulb fixture. Whether you're aiming for deeper blues (16K–20K), cool whites (12K–16K), or crisp daylight (10K–14K), we've outlined proven combinations to enhance your aquascape. For tanks heavy in LPS corals, consider adding a True Actinic bulb for dramatic colour enhancement.

16K – 20K – Bluish white with a noticeable blue and red under-tone

12K – 16K – Cool white with a noticeable blue and red under-tone

1 ATI Purple Plus

10K – 14K – Crisp white with just a hint of blue
