We've wanted energy bulbs for ages now and can neither find ones suitable for our lights, they either look hideous or take up more of the bulb and let out alot less light (which I'd imagine would be a waste of the electricity in itself).
These are lovely and nice an bright even before they 'warm-up, these bulbs are lovely barely look like they are energy saving ones as they match the size, bulb surface and shape of normal candle bulbs,the choice between bayonet and screw in is of great use as we have both sorts around the home.
