completely.. if the glass is not tempered, which I imagine its not, you do not want to use it. Also, it has no UV protectant. use the Lexan, but don't stick it too close to bulb as theres a possibility it could melt

I've never paid more than $5 for tempered glass. The source? Busted flatbed scanners from a computer surplus store. Tempered glass, large size, no "bug" etched on the glass. Just be careful removing it from the plastic case as it has some stout, double-sided adhesive strips holding it in.
