II. Wiring Diagram



As shown in figure above

HF output wire of the bulb can not be pressed, twitched or folded. 


The user can not change the length of the cable.


Short-circuit of interior or exterior of the wire can cause the damage of the lamp system.







Power supply wiring _ AC 220V, 2A (ampere) cable_ (L & N)

The power supply wiring is the electrical connection between the power supply and the electronic ballast input.  


This wiring must always use a 3-core cable for phase, neutral and grounding connections.


The phase and neutral of the power supply must be connected to the connector block as described on the housing label.


HF output wiring 

This wiring must be via the coaxial cable that is supplied as standard with the power coupler.  


Connections to the HF output of the HF electronic ballast must be made according to the color-coding of wires and the connector block.


The white wire must be connected to the +pole, and the black wire to the -pole.


Changing or extending of the coaxial cable is never allowed.

As shown in figure above

The bulb, HF electronic ballast and fixture must always be grounded separately.



III. Tips for Thermal Conductivity and Resistivity


  Keep the mounting flange of the power coupler at non-contact position of 20mm distance away from the HF electronic ballast for heat assistant reason.

  Ensure good heat transport to the surroundings (heat sinking).

  Use separate heat sinks for both the power coupler and HF electronic ballast.

  Avoid heat radiation from lamp to HF electronic ballast.

   Mount the bottom of the HF electronic ballast housing on its own heat sink; but never apply a heat sink for the test point only.

  Create a cooling airflow




IV.       Caution


Combination of a lamp, a power coupler and a HF electronic ballast; all with the same wattage indication.


Only system components with the same wattage indication (100W or 130W or 160W or 200W) may be combined!  Any other combination might cause damage to the lamp system components.


Every HF electronic ballast may only be combined with one lamp/power coupler set of the same wattage; failure to observe this basic rule might cause damage to

lamp system components.


Ensure firm electrical contact between all metal parts, the ballast housing and power coupler as well as correct wiring connection before turning on the power.


Spec. of the power supply wiring: bearing capacity - 2A current and 0.75mm2 x 3C (ground wire included).

Ambient Temperature: -10~+40

For your safety, turn off the power before installation.


If an abnormal condition exists, turn off the power and ask professional electrical technician for assistance.  Do not disassemble or attempt any repairs by yourself.


We are not responsible for any damages caused from improper fixture that is not provided or approved by us.


Do not light on the naked lamps (that means bulb and HF electrical ballast only) without assembling with fixtures over 15 minutes.


To prevent scald, do not touch the bulb when it is working.


Naked lamp cant be assembled with the fixture of no heat-dissipation device.


Use only our components to retrofit our EFL when necessary.

The pole of HF electronic ballast output is not earth wire.  Do not use any measuring machine to do any test.



 No colliding!!


  Risk of electric shock.  No Touching!!


If the bulb shows red light and then turns off when the power is on.  That means the bulb is damaged.  


Warranty void if seal damaged.
