I have to say I am happy with these candles. They give off loads of light and a surprisingly appreciable amount of heat, too, and when a few of them are used in close proximity they can feasibly be used to replace a small lamp. Great news for people like me who enjoy evenings in a mostly dark room with just ambient light.
Once you flick yer wick, about 10 seconds passes and the candles are nearly at their full brightness, with a very generous flame that sometimes climbs up to 2 inches high! The thing that I like about these is they aren't like tealights which take most of the evening to light up properly. They relight well too and burn just as well on subsequent lights as they did on the first, something that other candles often fail to achieve.
In other words; just buy them. Whether they are to be used for aesthetic purposes or practical purposes I am sure they will please. I hope these candles stay stocked on Amazon because I will be buying again and again!
