AOI UIS-P1 Strobe

The UIS-P1 introduces the next generation of TTL flash compatibility for OM System and Sony cameras, especially optimised for underwater use. Many AOI and Backscatter strobe users are already familiar with AOI's RC/SC and i-Macro exposure technology. With the P1, these precision TTL modes now also cover Sony cameras when using AOI flash triggers.

The P1 strobe features a super-bright ring flash tube that outperforms most high- and mid-range strobes on the market. With a 150-degree beam angle and a max output of 150 W, the P1 is powerful enough to cover most wide-angle situations. Also included is a 3000-lumen 90-degree video/focus light with a CRI of 90. 

Powered by two high-power 21700-type Li-ion batteries (not included), the P1 can fire up to 540 times in full power and recycle in 1.8 seconds after full discharge.  The simple rear interface is easy to use, and a self-orienting colour screen displays important information such as TTL mode, output level, and remaining flashes.
