LED Foam - 4mm

This is specialty LED foam, made specifically for diffusing LEDs. It's on the pricier side. If you've got a really small amount of space and need very efficient diffusion, this stuff really does work great. But at $8 per square foot, a large project could get pretty expensive.

LED Foam - 8mm

The 8mm foam looks roughly the same as the 4mm at close range, but seems to do a fair bit more diffusion as I give it some distance.

Packing Foam

This is a lightweight packing foam, sold as a mailing / moving supply. It's really thin and inexpensive - you can get a 150' roll of this stuff for $15. The price is right, but the diffusion is noticeably less good than the pricey specialty LED foam. It helps a bit to use multiple layers, but looking at this next to the expensive foam really points out how good the fancy stuff is.
