Q: What lamps is this ballast compatible with?
A: This ballast is designed specifically for 35W SOX low-pressure sodium lamps.

Q: Do I need a separate ignitor?
A: No. This electronic ballast includes ignition functionality and does not require an external ignitor.

Q: Is this ballast compatible with both 120V and 240V electrical systems?
A: Yes. The ballast operates on 110–240V mains voltage, making it suitable for use in most regions worldwide. For proper installation, please refer to the wiring diagram provided in the product images. Depending on the production batch, some ballasts may have diagrams or markings on the casing that reference 220–240V as the nominal or optimal operating voltage. However, these ballasts are designed to operate on both 110–120V and 220–240V AC power systems. Customers in the U.S. can use them without issue, and no voltage converter is required.

Q: Can I use this ballast with 18W, 55W, or 90W SOX lamps?
A: No. This ballast is designed specifically for 35W SOX lamps. A ballast matched to the lamp wattage is required for proper operation.

Q: Will this ballast work with Philips SOX lamps?
A: Yes. This ballast is compatible with 35W Philips SOX lamps as well as other 35W SOX lamps that meet the same operating specifications. For best performance and guaranteed compatibility, we recommend pairing it with our 35W SOX lamp.
