Frequently Asked Questions?

Find clear answers to common questions about product specifications, model selection, applications, and quotation requirements. For project-specific needs, send us your target market, required quantity, and key specifications.

Which ring size should replace my existing circular lamp?

Match both the outer and inner ring diameters and confirm that the G10q holder reaches the lamp connection without strain.

How is the color temperature selected?

Use the built-in selector to choose 3000 K, 4000 K or 6500 K before refitting the fixture diffuser.

Does the lamp use a standard G10q connection?

Yes. The series uses a G10q four-pin format, but the holder position and available fixture space must still match the selected ring size.

What is the difference between the S and U versions?

S uses AC 180-265 V with PF above 0.5, while U uses AC 85-265 V with PF above 0.9.

Can this lamp replace an integrated LED ceiling light?

No. It is a replaceable circular light source for compatible G10q fixtures, not a complete integrated ceiling luminaire.

Which certification marks are available for this series?

Available marks include CE, CB, RoHS, ErP and PSE for applicable configurations. Supplied marks must match the confirmed production version and destination market.
