When it may not be suitable
This ignitor is not compatible with lamps outside the 250W to 400W power range or with light sources that do not utilize high-pressure sodium or metal halide technology. It should not be used in applications requiring dimming control unless the entire lighting system is specifically designed for such compatibility.

Power range: 250W to 400W
Operating frequency: Standard mains frequency
Design: Electronic ignitor
How to use
Installation should be performed by a qualified professional in accordance with local electrical safety regulations. The ignitor must be wired into the lighting circuit between the ballast and the lamp, following the wiring diagram provided on the device housing. Ensure all connections are secure and that the power supply is disconnected before beginning the installation process. Once installed, the ignitor automatically manages the starting sequence when the power is switched on.
What to consider before purchase
Verify the wattage of your existing lamps matches the 250W-400W range
Ensure compatibility with your current ballast type
Check the physical space available in your luminaire for the ignitor dimensions
Confirm the lamp technology is either SON or MH
Usage recommendations
Always ensure that the ballast and the ignitor are matched correctly to the lamp specifications to prevent premature failure of the light source or the control gear. Regular maintenance checks of the electrical connections are recommended to ensure long-term system stability.
