I have double flood lights in my Skat Blast cabinet and I buy the lenses from TP Tool. On sale, and buy several they are not a bad price to be able see good.
Depending on the size of your window you can check around and but it by the bulk roll and save some money.
Mine is a fairly good size so when a friend gave me some sheets smaller than my window I left the full sheet stuck to my glass and just stuck the "smaller size" sheet he gave me over my bigger sheet. Worked for me for a year or so and I do a lot of blasting. All kinds of way so cut cost!
