What is the best way (cost/efficient) to create a candle light effect
I'm going to give you the poorman's way of doing this.
You'll need a tungsten light (I've used a 300w Arri for this effect), a 1/2 CTS Straw Gel (a bit more yellow than a CTO, plus it matches the color temp of a candle's flame almost perfectly) and some diffusion over your light. Point it at your actor from the angle that seems best to create the illusion of the light coming from the candle, probably above your actor's eyeline (keeping in mind to not create a shadow from candlestick/lighter you'll be using). And since you want to create a flicker look, simply have your gaffer or grip gently shake the light to create just enough inconsistency to simulate the flicker of a candle.
Finally, meter it just 1 stop under key, and you'll get an awesome candlelit shot. I did it for a lighting class recently, and it was totally believable.
