The Premiere dancing flame candle is a cheaper option for those wanting a moving flame electronic candle like the Luminara.
The 2014 version has the significant improvement of using a warm white LED instead of the lurid sodium yellow one from the previous year. It's not "flame" white, but it's a step in the right direction.
The circuitry is pretty much the same as the previous version and seems to drive the LED directly from the boosted power supply that runs the microcontroller (Probably a PIC12 variant or clone). The coil that deflects the plastic flame's magnet is driven hard and this causes the flame to click about noisily.
In the future it would be nice to see a more specifically chosen LED in terms of colour (golden white) and run it at lower current to make it more subtle. It would also be an improvement to tame the flame coil by adding a suitable resistor.
I don't recommend opening your own candle, since the casing is made of solid wax and the base is glued into it with a very gummy glue. It's hard to open the candle without breaking the wax.
