Sometimes all it takes to set the mood is your iPhone and 18 LED lights. Thats the theory behind Holi, a sleek and colorful lamp powered by your smartphone. Lastly, you can also use Holi to wake up in the morning — the lamp will slowly brighten to ensure your awakening is as relaxing as possible. While we dont know the price just yet, the Holi lamp is expected to make its way to the US starting in March.
