Nora3 Overview
Nora3 has two main LEDs. A focused
spot
LED and a wide angle
flood
LED. In normal operation the lamp
has
4 light settings
as
factory default.
Nora3 also has a separate
moon mode
LED (white smd LED) for maximum run time, and
battery charge
level indication
(white smd LED blinks 1-5 times).
Nora3 can be programmed using infrared remote control. From 1-9 light settings can be specified, and the
level of light provided by each setting can be configured by the user. The
spot
and
flood
LEDs can be
operated separately or blended together. Each LED can be operated at
low, medium, medium plus, high
and
maximum
, offering a choice from 26 possible light combinations.
Nora3 Operation
Nora3 is operated by the fully sealed switch on the top side of the lamp body. In normal operation, the switch
can be operated in two distinct ways,
<short push>
or a
<long push>
(push and hold).
The available light settings are in a continuous forward loop,
1 to 4,
and
off
. Each of the settings can be
selected in turn, by pressing the switch
<short push>
.
The
factory default light settings
are;
1. medium flood
(20 hours) - general progression around cave
2. maximum spot
(2.5 hours) - route finding in very large passages
3. medium plus flood & low spot
(10 hours) - progression in larger passages
4. high spot & high flood
(2 hours) - if you really must !!
5. off
(effectively zero battery consumption)
In order to avoid cycling through subsequent light settings, Nora3 can be
turned off
from any setting with a
long switch press
<long push>
.
Note - when initially connected to the battery pack, Nora3 will turn on in moon mode (separate white SMD
LED). The next press of the switch (short or long)
<push>
will turn the lamp off, and the smd LED will indicate
battery charge level.
Nora3 has effectively zero battery consumption when switched off, so there is no particular requirement to
disconnect batteries. However it is always best practice to do so when not in use for more than a few days.
Auto Transport Lock
Nora3 has an auto transport lock feature, to avoid the lamp being turned on accidently. When Nora3 has been
switched off for more than
5 minutes
the transport lock is automatically activated. To restart lamp
subsequently requires two presses of switch
<push-push>
in reasonably quick succession.
Moon Mode LED and Battery Charge Level Indicator
Moon mode is provided by a separate white smd LED, providing
very low
light (approx. 8 lumen) for ultimate
duration (320 hours / 2 weeks). Well suited to underground camp, expedition, small passage caving, and
emergency. Moon mode can be selected by a long switch press
<long push>
from lamp
off
setting.
The next press of the switch (short or long)
<push>
will turn the lamp back off. At this point the white smd
LED will display level of battery charge by blinking 1 to 5 times. 5 blinks indicates fully charged and 1 blink
very flat, for li-ion batteries. The light is visible underground, on the back of your hand, such that battery
condition can be determined without removing your helmet.
