Hikari SQ:

the ultra-thin LED light source.

Why choose between form or function when you can have both? Inspired by advanced smartphone display technology and a determination to deliver a commercially viable and functional ultra-thin lighting product, we created Hikari SQ: the ultra-thin light source with the performance, manufacturing and commercial advantages of LED. 


Inspired by advanced smartphone displays.

Just 3.2mm thin and weighing only 35g, each Hikari SQ module emits up to 450lm of low-glare, CRI 93 light. No additional heat sink or optics are required and it is compatible with standard LED drivers and DALI dimming.


Explore the possibilities of ultra-thin lighting design.

Hikari SQ delivers maximum creative freedom for a new generation of decorative and architectural lighting designs. View the full range in our online webstore or order a developer kit to experiment with your own designs.
