These signs have the fluorescent "Yellow Green" 3M diamond grade sheeting. This material has an approximate reflectivity of 1000 foot-lamberts per square inch. Standard Engineer Grade Reflective Sheeting is rated at approximately 70 foot-lamberts per square inch. Diamond Grade can be seen from one mile away at night. This material may cost more, but for maximum visibility and the increased safety it provides, we think it is worth it.
