i have a plastic draw and had it setup to keep an african bullfrog in it ,except the light so i cut a square in the top and i used siliconized acrylic to glue some hardware mesh on the square hole.im going to use a fifty watt heat lamp and the acrylic is not going be directly under the bulb, will it melt or give off dangerous fumes that might harm my herp.i will only use it in winter.:]
