If you feel disappointed when you find the LED vanity lights you just installed are not bright enough or are not dimmable with the dimmer switch on the wall, then please consider this item. You can use it as a sole light source for a single-sink bathroom; it's the equivalent of four-light vanity lights. You can use it with the same dimmer switch as traditional incandescent light bulbs. You can adjust the light direction by repositioning the light bar. You can install it easily; the installation complies with US electric code.
