White translucent acrylic sheet
Milky white acrylic that spreads light evenly, cut to size in 1/8, 3/16, 1/4, and 3/8 in. It hides LEDs and bulbs far better than frosted clear, which is why it's the usual face for light boxes and backlit signs. Thicker sheet passes less light, so pick the thickness to match how bright your lights are.

Details
- White translucent (light diffusing) acrylic in 1/8, 3/16, 1/4, and 3/8 in.
- Light transmission depends on the grade and drops with thickness; Acrylite white translucent grades run about 31 to 54% at 3 mm
- Sold by nominal thickness; actual sheet usually measures a little under the label, so tell us if a part has to fit exactly
- Laser-cut edges are glossy straight off the cut; machined, flame-polished, diamond-polished (straight edges), and sanded edges are also available
- Most colored sheet isn't covered by the FDA food-contact rule that clear sheet from major makers meets, so don't use it for direct food contact

Questions
How much light does white translucent acrylic let through?
Typical grades pass about 30 to 55% of light, less as the sheet gets thicker. That's lower than frosted clear, but it hides the light source much better.
White translucent or frosted acrylic for an LED diffuser?
White translucent gives the most even glow and hides individual LEDs. Frosted passes more light but you'll see hot spots unless the LEDs sit well back from the sheet.
How far should LEDs be from a diffuser?
A common rule of thumb is at least as far as the LEDs are from each other, and 1.5 to 2 times that spacing for a smooth, dot-free glow.
