Product Information

Ikelite DS161 Underwater Strobe Flash is a professional underwater strobe built around a round xenon flash tube that delivers a Guide Number of 24 at 1m/ISO 100 and a 500 lumen diffused LED video and focus light with 10 brightness settings plus SOS mode. It connects to an Ikelite camera housing through an Ikelite ICS 5-pin sync bulkhead and carries a depth rating of 100m (328 feet).

Who it is for

The DS161 suits underwater photographers and videographers shooting through an Ikelite housing who want a single strobe that also functions as a continuous video light for close-up, macro, portrait, and wide angle fill-in work, as well as a focus assist light. The video light output automatically turns off and back on when a still photo is taken, so it will not overexpose the frame. It also supports TTL exposure when connected with Ikelite sync cords to an Ikelite camera housing, and it can be paired as a dual-strobe set.

  • 500 lumen LED video/focus light with 10 brightness settings plus SOS mode
  • Powered by a 7.2V 3300mAh NiMH rechargeable battery pack, rated for 300 flashes per charge at full power

Compatibility and sizing

The DS161 connects via a quick-release toggle system and requires an aluminum ball joint arm; it is not compatible with the Flex Arm, which only supports the DS51 strobe. Its NiMH battery pack (product number 4066.5) is shared with the DS125 and DS160 strobes. For two-strobe setups, it can be ordered with the SA-100 Arm System and a dual Ikelite TTL sync cord as package #3945.02.

Does the Ikelite DS161 support TTL exposure?

Yes. The DS161 supports TTL exposure when it is connected via Ikelite sync cords to an Ikelite camera housing. It also uses an Ikelite ICS 5-pin electrical sync bulkhead for the connection.

Is the Ikelite DS161 compatible with the Flex Arm?

No. The DS161 requires an aluminum ball joint arm for mounting. The Flex Arm only supports the DS51 strobe, so it is not compatible with the DS161.

Can I use two DS161 strobes together?

Yes. The DS161 can be set up as a dual-strobe system using package #3945.02, which pairs it with the SA-100 Arm System and a dual Ikelite TTL sync cord for two-strobe lighting setups.
