The first option is submersible battery operated tea lights. These lights are found in the floral sections of your craft store. They are meant to be put in vases of floral arrangements. The casing is smaller than standard candle led lights and the light is brighter. Plus, you can get them in a variety of colors, shapes, and sizes. You have to remove a piece of plastic to activate the batteries. This one turned on by twisting clockwise. You can find the ones I purchased here: https://www.amazon.com/gp/product/B005W4P8ME/ref=oh_aui_search_detailpage?ie=UTF8&psc=1.
Another fantastic option is paper lantern lights. These lights are also very bright and come in a variety of colors. What makes them so perfect is their size! These are small so they will fit in a variety of settings. There is also a small hole at one end which makes them perfect to be hung with string. You also have to remove a piece of plastic to activate the batteries and they turn on by twisting clockwise.

These lamps are solar lamps purchased from the dollar store. The solar mechanisms did not work. I completely removed the solar components of the lamp by simply popping it out. I then decorated the shade with black jewels and glued the shade directly to the lamp base. I placed a paper lantern light in each shade. I held it upright with a tiny bit of poster putty.
I love how the lamps turned out! The rooms are filled with a wonderful bright light. These pictures were taken with all other lights off and no camera flash. These bulbs would also work great in a variety of night-light casings such as lanterns or sconces.
