Ikelite SubStrobe 400 Underwater flash

Recognized as the most powerful underwater strobe offered by any manufacturer, the new Substrobe 400 produces an unprecedented 400 watt-second beam covering an ultra-wide 110 degrees. This power strobe offers a wider range of aperture choices for increased depth of field. It is especially suited for wide angle photography as it covers the Nikonos 15mm and SLR 18mm lenses without the need of a diffuser. The special soft-lite reflector provides rich reds, oranges, and warmer flesh tones. The built-in aiming light shows the colors in your subjects and is powerful enough to use as a night diving light. The Guide Number (ISO 100) for Surface/Underwater is 100/50. The industrial grade ni-cad module recycles in a quick 3-seconds. Both visual and audible ready signals convey flash readiness and confirm TTL operation. The Substrobe 400 also operates in three manual power modes.
