Our light lens cover is made of a strong but flexible clear acrylic. These fluorescent light covers (also know as a lighting diffuser) are ideal for all types of commercial and residential lighting fixture frames/doors and also with sizes large enough to fit in a standard ceiling grid system without the need of additional support. These are the best and strongest lenses made. This quality lens can't be found in your local home center store. PLEASE MEASURE AND ORDER CORRECTLY! WE DO NOT ACCEPT RETURNS VIA SHIPPING METHODS.
