When I bought this night-light lamp about 4 years ago for the kids room, I always bought colored bulbs in yellow or orange for it. Those bulbs added a warm and cozy mood to the room. As the years went by I realized that they were not always so easy to find and they can get pretty pricey.
Recently, the bulb blew and I asked hubby to pick up a new one at the local hardware store. Not knowing that I needed a warm and cozy bulb, (of course) he bought a bright, (brighter than the sun) LED bulb. He said they were energy efficient so I didn't bother to have him return it. For about a week or so we had to place a sheet over the lamp to dim it's glare. It was so bright I was afraid it would wake the kids from their sleep.
I realized I had these awesome paints in my craft bin. This was exactly what I needed to solve my issue. This stuff is great on glass, ceramic and tiles. You can find them at Michaels craft stores.
NOTE: Since this is an LED bulb, it is ok to paint because it does not drive heat like regular bulbs do. Please DO NOT paint regular bulbs. Be sure to only use glass paint.
