Instruction & Use
This is a high technology electronic controlled light based on LED¡s in three colors: red, green
and blue. These three base colors together can produce many other colors to create the perfect
atmosphere in the pool. Any of the 16 pre-programmed effects can be selected with the on/off
switch of your pool lights. The LED¡s can also be warm white only or natural white only. The
LED¡s are driven by constant current. The technology of True PWM is adopted on the lights.
High temperature protection makes the LED¡s be protected while the internal temperature
reaches a high level. All these technologies guarantee long working life of the LED lamps. The
lights must be used / operated while fully submerged underwater only.
?This lamp is designed to be fixed in new pools and/or pools with existing surface mounted

Installation
All lamps should be placed on the wall of the pool below the water surface, in areas that are
easily accessible from the upper edge of the pool.
?All lamps should be installed on the same transformer and switch.
?The lights can be installed for both concrete pools and fiberglass pools.
?The lights fit into standard 1.5¡¡wall fittings of swimming pools.
?The lamp is supplied with cable of 2m, 4m, 6m, 10m, 16m or 20m according to the need of the
user, making it possible to install multiple lamps connected to a single junction box.
The light can befixed on concrete or stone wall pools, thin wall pools, fiberglass wall pools,
metal wall pools, or wooden wall pools with liner.
It can be threaded into the 1.5¡¡female-thread wall fitting or conduit/pipe

The below drawing shows how to connect the cable from the lamp to the power source.
Maintenance & Replacement
There is no maintenance required for this lamp ¨ it is designed to be used only once, meaning
that replacement is necessary if it becomes defective (repairing is impossible). Before any
handling, ensure that there is NO voltage supplied to the lamp. The light is designed to be
replace without cutting any cable. To replace, unfasten the lamp from the wall fittings, unfasten
the nut and disconnect the wire. Then connect the wire to a new lamp and fasten the new lamp
with the nut, and then fasten the light back to the wall fittings. Ensure the new lamp is of the
same model and characteristics as the one being replaced.
Start-up
?The lamp should only operate underwater whilesecured to the vertical walls of the pool. Never
switch on the lamp if it is not underwater.
?In case of colored lamps, 16 pre-programmed effects and combinations may be selected using
the on/off switch of your pool lights. Just switch off and switch on within 2 seconds.
?If the light is powered off for more than 20 seconds, it will keep the latest program when it is
turned on again.
?To achieve synchronization, confirm all lamps are installed correctly on the same switch, after
they are powered off for more than 20 seconds, switch on and switch off continuously three
times, and then finally turn them on again. They will all go to program 5. Now you can select a
program for them by switch off and on within 8 seconds.
?Alternatively, we recommend using our optional controller (with in-built safety transformer)
which comes with (a) remote control for easy operation and (b) auxiliary connection of 24V for
operation of any other electrical item.
