LED 16 DUO VIDEO LAMP HEAD:
➢
is a lamp used as the main lighting source for photo and video shooting during recreational and technical diving and for underwater
works with image recording
➢
construction:
•
head body is made of surface anodized aluminium
•
magnetic switch (without a pass through the housing) allows switching eight or sixteen LEDs by rotating the ring at the back of
the head body, the switch works in both ways, working in positions:
off
–
8 LED
–
off
–
16 LED - off
•
connection lamp head to the battery by high quality flexible cable; protected against bending with plastic covers (at the plug
and head ends)
•
optional connection by e/o cord
–
this option is available only when using a battery with a switch (necessary to cut off the
power supply before unplugging the cable); e/o cord cable polarization at the lamp head: "minus" in the output, "plus" on the
pin (other connection may cause damage)
•
hermetic connector on the cable is protected against the admittance of water (eg. mechanical damage to the cable); the
polarization of the plug: "minus" on the body, "plus" on the center pin (other connection may cause damage)
➢
lamp head, as the source of light, has sixteen Cree XML-2 diodes, with a color temperature of 5500 - 6000 K
➢
requires 12
–
16,8 V power supply, use of higher or lower voltage can damage the lamp head
➢
tested to a depth of 150 meters, 300 meters on request
CONTAINER WITH BATTERY PACK:
➢
body built of anodized aluminium, with upper and lower lid of delrin
➢
in “delrin” version the entire
container body is made of delrin
➢
has a pressure valve in the lower lid which protects against excessive pressure within the container
➢
on the upper lid there is one output (capacity 6.8 Ah) or two outputs (capacity 10.2 Ah, Ah 13.6, 23.8 Ah and 41 Ah) to connect with

tested to a depth of 150 meters, 300 meters on request
BATTERY PACK:
➢
consists of Li-ION battery cells which feature small size and high capacity
➢
has a low self-discharge level (approx. 4% / month)
➢
has an electronic protection against: short circuit, overcharge and over-discharge (excessive discharge causes switching off of the
battery)
➢
