Overview
The Sundaya Lightkit system
consists of very simple
modular parts that you can
connect together to form an
expandable, energy-efcient
lighting installation.

The concept of the basic
Sundaya Lightkit is simple.
During the daytime, energy is
harvested from the sunlight
using the LEC (Light to Energy
Converter), and converted
into electricity. This electrical
energy is then passed through
the cables and Hub4 in your
installation, to the Ulitium
lamps.
How does it work?
Energy Harvest
LEC

5
When not in use, the Ulitium
lamp will store this electric
energy, and then convert it
back to light whenever it is
switched on. It is considered
an ELC (Electricity to Light
Converter).
You can have as many LECs
and ELCs in your installation,
as long as there is a good
balance between energy
harvested and energy
consumed every day.
The harvesting capacity of
the LEC in every Sundaya
Lightkit has been chosen to
be in good balance for the
number of energy consumers
included in the kit. If you want
to add more energy consumers
(lamps, TV, laptop computer,
etc.) please also consider
installing additional LECs to
maintain this energy balance.

Before you begin installing the
system, please consider where
you would like to suspend the
lighting, and the LEC’s location
on or near the roof.

Equator
The LEC needs to be able to
face the equator, so choose
the correct side of the roof.

Judge the best placement
and height for your Ulitium
to get the light distribution
you want for the room. See
the chapter on how to switch
on the Ulitium if you want
to study beforehand its light
distribution in the room.
The LEC must not be
overshadowed by trees or
buildings throughout the day.
Make sure the total distance
from the LEC to the Hub4 and
the energy consumers will
not exceed the length of the
cables. The Hub4 should be
placed above the ceiling, at
roughly equal distances to all
the devices.

The LEC is designed to be
mounted on a rigid pole. An
alumunium or galvanized
pipe of diameter 26 mm is
ideal, but a thick PVC pipe is
acceptable. The pole should
be mounted on the rooftop,
clamped or tied to the truss of
the roof. If you cannot mount
it there, you can also nail
the pole on the outer wall of
your house that is facing the
equator, as long as the LEC is
not overshadowed.
Installing the LEC
The Sun
Tilt
angle Equator
It is very important that the
LEC be positioned facing the
equator. If necessary, also
adjust the LEC’s tilt angle, so
that at 12 o’clock the sun’s
rays should fall straight on
the LEC’s top surface for
an optimal sunlight energy
harvest.

9
Connecting the
Hub4
Under the roof, place the Hub4
somewhere between the future
locations of the Ulitium lamps.
(For 4 Light kits, connect
one Hub4 to another using
the extra cable with Bayonet
Plugs).
Insert the Bayonet Plug of the
cable from the LEC, to one of
the four ports on the Hub4.
Twist clockwise the Bayonet
Plug to lock it in place.
OPTIONAL: for longer
distances, you can also
connect two Hub4’s with
an optional Sundaya DC
cable, wired to the terminals
underneath each Hub4.

10
Installing the
Ulitium
The Ulitium is designed to be
suspended from the ceiling.
At precise location on the
ceiling where you have
planned to suspend the
Ulitium, drill a hole 2 cm in
diameter, barely large enough
to allow a Bayonet Plug to
pass through.
Insert Bayonet Plug of the
cable provided, into the port
on top of the Ulitium.

diam. 2 cm

11
Pass other bayonet plug and
rest of the cable through the
hole in the ceiling you just
made.
Slip cable into Celing Cap
provided, through a slit on its
side.
Maintain the Ulitium at desired
height. Then fasten Ceiling
Cap to the ceiling with screws,
covering up the hole on the
ceiling.
Connect the bayonet plug that
has been passed through the
ceiling, to any available ports
on the Hub4.
Repeat the above steps for all
lamps in the kit*.
*) for Lightkits 2,3 and 4.

12
Operating the
Ulitium
When the Ulitium is shipped
out of the factory, the
electronic circuitry is not yet
activated.
Press once the Master Switch
at the bottom of the Ulitium to
activate the unit.
(When storing the lamp away
for a long time or during
transportation, do not forget
to deactivate the circuitry by
pressing again the Master
Switch).
The cord length can be
adjusted by pulling out the
Spool inside the Pull Switch,
and then winding or unwinding
the cord.

To switch on the light, pull
down once on the Pull Switch.
The lamp brightness is set in
progressive steps, the rst
being at 100%.
Pull once again to dim the light
to 50% brightness.
Another pull on the Pull Switch
will dim the light down to 10%
brightness.
Pull again one more time to
switch off the light.
So, to get to the desired
brightness after turning on the
lamp, cycle through by pulling
down the Pull Switch several
times.

14
Once it is full and can store
no more electricity, the red
indicator light will light up.
If the Ulitium has no more
electricity in its storage, it will
not be able to provide lighting.
Try using it at lower brightness
settings, or allow it to store
electricity back to full the next
day, before using it again.
Avoid wasting energy. Dim or
turn off the lights when not
needed. During the day when
it is already bright, avoid using
the Ulitium, and just let it
store the energy harvested.
When the Ulitium is storing
any unused electrical energy,
the green indicator light inside
the grated plastic lens will
start to blink.

15
If for some reason, you
tried switching on a Ulitium
and it does not want to
light up, please follow these
troubleshooting steps:
1. Push the Master Switch, and
then try switching on again.
2. If during daylight the green
indicator is blinking, give
the lamp some time to store
enough energy before using
the lamp again in the evening.
3. Try unplugging the Bayonet
Plug on the Ulitium and
plugging it back in, before
attempting to switch on the
lamp again. This will reset the
Ulitium’s protection circuits.
Troubleshooting
4. Check the cabling from
the LEC all the way to this
Ulitium, and verify all plugs
are connected, to make sure
the Ulitium has been getting
energy from the LEC during
the day. If a cable is broken
or damaged at some point,
replace.

All Sundaya products are rated
in Joules for energy harvest,
storage and consumption, and
Lumens for light output of
lamps.
Joule is the unit to quantify
energy (all forms of energy
can be quantied in Joule).
The higher the Joule number,
the higher the energy amount.
Lumen is the unit to quantify
total amount of light emitted
by a lamp. The higher the
Lumen number, the more light
it emits.

The Sundaya solar panel
range is named LEC (light to
Electricity converter) followed
by a number that indicates the
amount of electrical energy (in
kiloJoules) that it can harvest
at 4.5 sun-hours per day (4.5
sunhours is the average in
tropical regions).
During bad weather or cloudy
days the sunhours can go as
low as 3 sunhours per day, and
in very bright days as high as
6 sunhours per day.
The next table gives the range
of daily energy harvested from
the available LEC range.
