Hi Arthur: I have not looked into this but an LED can be the size of a head of a pin. The new lights when you take off the cover look like a six shiny pin heads on a black surface. Without the light diffuser cover the light can be very blinding, like an arc-welder. OTOH, wax can be mixed with chemicals to make it burn different colours. Copper nitrate for green, strontium nitrate for red, sodium nitrate for orange and so on...

But unless they are using nano-tech, there were no discernible traces of anything electronic once the wax was gone. So I am left with two conjectures: a) it's in the wax, or b) said electronics melt without trace one the last of the wax is gone. I have lots of difficulty subscribing to the latter explanation. That's not to say that I have irrefutable evidence to the contrary, but my simple ignorant experiment (burn the candle until there's no wax left) yielded no traces of anything metallic or otherwise. Hardly hard science, I grant you. But the casual and ignorant observer notes that a) this experiment is repeatable; and b) there are no apparent traces left once all the wax is gone. This leads me to conjecture that it's in the wax itself, some substance melted into the wax at candle-formation time. I am not standing in any direction on this. Frankly I am mystified. The definitive answer lies somewhere in China, within a company that manufactures these candles at a price which after import taxes, overseas transport etc., retail markup, results in a candle-in-a-glass that retails for about a dollar, in CDN currency. At that price, I cannot fathom how it could be done with LEDs. But I'm just a stupid guy from Winnipeg who can program a 500-table database and can't even figure out how his $1 candle works. I'm beginning to think that I'm a relic on this planet. It's going way faster than I can cope with, but I have yet to quit and accept the fate of Drowned. When in doubt, play Chess.
