Polycarbonate and Acrylic are both well known as transparent plastics. They have wide applicability in a number of industries and can often be used in conjunction with one another to take advantage of various material properties.
1. Polycarbonate (PC): Polycarbonate is well known and widely used for several prominent reasons. First, it has extremely high impact strength for a plastic material. This makes it an ideal choice for use as a composite material in bulletproof glass and/or for riot gear (plastic shields) used by police to combat a riotous crowd. Polycarbonate also has very high transmissivity. That is, it allows very effectively for the passage of light. Combining its impact strength and high transmissivity makes polycarbonate an ideal material for commercial greenhouses used in northern climates.
2. Acrylic (PMMA): Acrylic is also well known for two principal characteristics. First, like polycarbonate, acrylic has very high transmissivity (it allows for the passage of light). Second, acrylic is extremely scratch resistant. Because of these two qualities acrylic is frequently the plastic of choice for optical devices. Another characteristic that makes acrylic a great choice for optical devices is that relative to glass acrylic is much less damaging to skin or eye tissue when it is fractured. This is actually a characteristic common to most plastics (not just acrylic), but it is extremely relevant in the case of acrylic because it is more frequently being chosen as an alternative to glass for optical applications.

Usually, lights voltage working voltage is 10-30V. However,some customers need custom made 10-80V or more,it is also acceptable according to the lights application.
