These little lights throw off a lot of heat in the mantis containers. Can raise the temp over 10~ F Hole size needed to fit into containers is 7/8". Kit includes a light bulb pack, screen to glue over bulb case, night light fixture with cord. If purchasing a container with the kit, I will drill hole in container for you. If you do not want me to drill hole, please state that on order. Remember when misting a container do not spray the light.
