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.

My little five-year-old friend was so excited to receive this as a birthday gift and has been having fun playing with it non- stop!

My niece keeps asking for legos so I went even better. I got her the light up kind. She LOVES THEM


Awesome for Easter Eggs

I purchased this with the basic sets and put the bases in Easter baskets and had the kids find eggs with the blocks inside. Only problem is that I want to play with them when my kids go to sleep and they want to use it as a night light.More > < Less


Great company and product

We did a throw back gift for Christmas for each of our children this year. I purchased these for my 25 year old son who loved building with Duplos and Legos when he was growing up. This was such a hit. He said he wished these were available when he was a kid. And, I must add, their customer service is amazing. Great company, highly recommend them and their product. Plan on ordering more of these as gifts to inspire "real" 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.
