FAQ

• My tube flickers but won't light — is this the fix?
  Often, yes — a worn starter is a common cause of flickering or failure-to-start tubes.
• Can I install this myself?
  Yes — it simply twists in and out of a small socket in the fitting, no tools needed.
• How do I know if I need S2 and not another size?
  Check the markings on your existing starter — S2 suits smaller 4–22W tubes; always match to what's currently fitted.
• If a new starter doesn't fix it, what's next?
  The tube itself may be at end of life — try a replacement tube next.
