It's a pretty nice sized lighting fixture. You can find the LEDs on Amazon. I got these and it sparkles at different shades of light.

JandCase G9 LED Halogen Bulb, 5W, 40W Incandescent Equivalent, 400LM, 2700K/4000K/6000K Available, Adjustable Daylight White/Soft White Bulbs for Chandelier, Ceiling Fixture, 6 Pack

Just remember to turn off power at the main junction box, remove your old lighting fixture, connect ground wire first, then the white to white, black to black and if you have a switch which may be red, connect that to the black live wires. 

Everything else about the light is great.
