DIY plexiglass top

hi i just got a 40 gallon tank from my friend. i got everything for it but he couldnt find the top for it "hood?" ive made one out of plexiglass and im almost finished but had a question. do i need to cut out a hole for where the light sits on it or would the light be ok sitting on the plexiglass? i dont think it would be a good idea to have the light sitting directly on the plexiglass but was woundering what everybody else has. thanks!

depends on the thickness....if its quarter inch and your ballast isnt to hot its cool...but i like to elevate the light a tad ....i use egg crate or scrap acrylic to boost it up a 1/2 inch...

plexi melts at a relatively low temperature, it is dependent on how hot your light gets. Elevating it will solve your problem as badxgillen said. You could also cut a hole and put a piece of glass over the hole and put the light on the glass.

one word of caution.. if the light does not have its own protective shield to keep moisture out condensation could be a danger!!! i would suggest even if you do cut the hole raise the light fixture to allow evaporation to NOT settle in the light...

i just would not want to read about you in the paper...
