Waterproofing
Safe to use at a maximum depth of 197'. The battery compartment cap is secured via double o-ring seal as is the main body of the housing which also has a gasket as an enhanced barrier against water penetration. To eliminate possible leakage through the housing, Ultramax has used a simple reed switch controlled by a powerful external magnet. The battery compartment is completely isolated from the electronics in order to prevent water damage to the strobe if the compartment is accidentally opened or batteries are changed when the unit is still wet from a dive.
Guide Number
Features a GN of 66' at ISO 100 on land.
Power Rating
Features a power rating of approximately 25 watt-sec.
Coverage
Offers a coverage angle of 90°, which is 50% wider than Ultramax's previous model and can be increased to 100° using the supplied diffuser. The diffuser also softens the light to prevent backscatter, glare, and hard shadows.
Color Temperature
Daylight-balanced at 5700K.
Modes and Triggering
Offers manual exposure control. There are 5 pre-flash settings to synchronize with the built-in flash of most digital compact cameras. Choose from 5 power/brightness output levels ranging from 20-100%. The strobe also has slave functionality, allowing it to be triggered by the firing of another flash. An optional Fiber Optic Cable Kit (#UXDS-FOC) is also available.
LED Indicators
There are five LEDs that indicate power level, along with a green LED power ready light featuring a blinking function that indicates low battery.
Power
Runs on 4 AA alkaline or NiMH batteries, which are available separately.
Construction Details
Durable housing made of corrosion-resistant polycarbonate.
Mounting
Standard YS connector for attachment to a lighting arm with a YS mount, such as Ultramax's UXFA-1 or UXFA-2 Flex Arm. This arm can then be mounted onto their UXST-1 single or UXST-2 dual lighting arm tray or another tray with standard T-1 connectors. These trays also give you a mounting point for your camera housing and provide improved handling and balance beneath the water's surface.
