I've been meaning to ask this for a while now, after searching through the literature and past threads on Lttd turned up nothing specific to my question.

In Ritual, when using candles for general illumination of The Chamber and not the burning of requests, is it 'kosher' to light those candles during non ritual? And vice versa?

I know it's ill advised to light request candles out of context (Secret Life of a Satanist), and even if it hadn't been documented, would still raise eyebrows. I'm wondering if anything has been experienced or deduced or what have you that it's unwise to light other candles that were used during ritual solely for illumination. If using them for ritual and non ritual is, shall we say, 'safe', that'd make my life a bit simpler when ritualization is required.
