I respect her endeavour. Except why go through all that trouble when you can just get a continuous light that doesn't annoy anyone?
Seems to be that just about no-one are annoyed by continuous lights. And they can be cosy too. Moreover, with fancy new LED technology (sorry for the slight sarcasm) you can even have it in paper lamp shades, or whatever nicely done Art Nouveau creation you like.
She then drilled out parts of the core of some large candles using a hole saw, and put these LED candles in there.
So now she enjoys candles every evening without the fire risk, poor indoor air quality during winter season and the expense of new candles.
