Review on 💡 Dazzle Your Space with Comyan Halogen Dimmable Chandeliers Lighting: Perfect Blend of Elegance and Ambiance by Popeye Knight

The bulb of a table lamp bought many years ago has completely burned out and I don't want to throw the whole bulb away. This is a 12v 20w JC type and I can only find this 10 bulb deal from Revain for a single bulb replacement. It works as advertised but I'm not sure what to do with the remaining 9. Since the first lightbulb lasted over fifteen years, this lightbulb can survive the transformer.
