This Light Pillow from Linus Kutavicius isn't the first glowing pillow we've ever seen, but it's about the only one you can actually own. The light source (presumably LED) is said to be contained in powder-coated metal frame, which doesn't sound very comfortable, but at least there's a washable cotton cover.

No word on the wattage, but it looks like the perfect light source when you need a soft glow to read by, but don't want to disturb your partner snoozing beside you.

You can get the square (18 x 18 inches) pillow for $189, which hopefully includes batteries. Kinda pricey, but then again you're getting a pillow and desk lamp in one. Hmm… even then it's kinda pricey.
