I’ve just read a BBC web article about the economics of lighting throughout human history, which I found quite interesting:

Fascinating, i always wondered at the light output of a candle, though i assume 13 lumens is not gospel
My unanswered question is how many lumens per watt is it?

I would be interested in an efficiency comparison, a wood fire compared to a 100lm/w LED bulb.

I’ve read before that a candle burning is about 80W. Based on the 13 lumens number, we can estimate .1625 lumens per watt.

You are correct, thank you :slight_smile:

I’m glad you enjoyed it :slight_smile:

I’ve just been reading Bort’s Wikipedia candle link and wandering off along the links it gives, so thank you in turn! I had no idea there were so many ins and outs surrounding something as seemingly simple as a candle…

@ Phlogiston,

Many Thanks for the link.

Interesting article.

I make “Melt and Pour” jar candles and add scents to them as a hobby, so appreciate how time consuming it can be even with modern methods and materials!

Thankfully we have LED’s for light!

Cheers,

Nice read! Actually, I replaced all old bulbs at my home with LED light bulbs. It cost me much less on electricity bill last year.
I hope LED lights could make further progress to save energy and cost.
