I went thru the tea light phase. Bought a tea light candle holder etc...I'm over it.
I have multiple LED flashlights in cars, on night stands, in BOBs etc. Mag Lights in all the cars and one in the house too. Photon II Micro Ligts on every key ring and every emerg bag.
Multiple oil lamps in the house, with xtra wicks, oil and globes.
And started stashing some of the cheap religious candles after discovering they last for a long time and are cheap and available at most grocery stores.
And one e-kit has a NuWick 120 with xtra wicks. I wouldn't pay to ship one to my house but if they had 'em for a good price in a store I might get another for a base camp e-kit. But they are spendy so I'd probably go with the religious candles....you can get quite a few for the cost of a NuWick and have light in multiple locations. With a little care in packing them away to can address fears of breaking the glass they come in.
Have been lusting after candle lanterns too ...WalMart has 'em pretty cheap ... Lantern and xtra candles for like $20. They should work good enough for back up in car kits, BOBs and such. And I hear that the citronella candles work well in them too so might help with the flying pests in you are in such an area.
