Light Stax is a light-up building block system powered by LEDs. Build up from the base, and each time you add a new block, it lights up. Brings light and striking color to kids’ creativity (and can even be a nifty night-light afterwards). And for grown-ups, Light Stax creations stand out on an office desk, too.

Love it!!

I bought this item for my son's 4th birthday and he loves it. We use it as a nightlight, the setting that turns off after 15 minutes is perfect. I do wish there was another option between this set and the $99 set to get more blocks.More > < Less

I've now bought 3 of these starter sets as gifts for children one-and-a-half to four years old. Twelve blocks are a manageable number for young ones, and their parents never seem to get tired of playing right along with the kids!More > < Less

About Light Stax

Light It Up

Light Stax are the new building blocks on the block—they glow via internal LEDs. Build a structure on the electric-powered base, and each block you add lights up. The result will be a multicolored statue of light that can blink, fade, or stay steadily illuminated.

Inventor Johnny Lin got the idea for Light Stax while at a toy fair in China. He saw plenty of building block systems and LED-based toys but no combination of the two. A light went on (so to speak), and five years of development later, Light Stax was born. Johnny is now an award-winning toy designer.

For kids, Light Stax is a bold way to play creatively. They can build a self-dimming nightlight. Or mix and match with Duplo blocks. As long as the Light Stax bricks remain in sequence, they’ll light up.

And if you’d rather play with Light Stax yourself, they make a standout addition to an office desk. When it comes to these building blocks, there’s no age limit.
