Replacing Chandelier Bulbs

Tang my guess is that the LED bulb, if it draws less than 15w, would work just fine

However it's not clear what sort of bulb or bulbs it originally used nor whether it has any sort of semiconductor or other dimming provision; while other aspects of your problem remain somewhat cloudy. For instance when you say, '...choose one...' it's not clear whether one fixture or one bulb, and when you say '...the LED...,' we're not sure whether you're making ref to the original bulb or one you wish to substitute

Desi you might also indicate whether or not the chandeliers are independent

As far as electrical safety goes, you should be fine with any bulb that does not draw more than 15 watts.

So if you got a 14 watt bulb that was marketed as a "90 watt equivalent", you'd be OK. It is really just a 14 watt bulb.

However, you might want to consider how bright you want everything to be. If turning on the light starts to resemble the flash of a nearby nuclear explosion, perhaps you'd want to consider less potent bulbs even if your fixture can handle more.

And like dalehileman said, if your fixture has a dimmer, make sure the bulbs are dimmer friendly.

Another consideration is, LED bulbs often have some sort of radiator to disperse heat from the bulb. Make sure your fixture doesn't impede airflow around the bulb's radiator, or the bulb will overheat and stop working.
