For one day only, a light therapy lamp from Miroco is down to an all-time low price of $27.99. This shell-shaped lamp offers three brightness levels, which can be adjusted with the touch of a finger, with a maximum brightness of 10,000 lux — thanks to UV-free LED lights — to mimic the sun’s rays.

We’ve previously recommended a similar lamp from the same brand, though the one in Monday’s Gold Box boasts an equally impressive 4.8 out of 5 stars and over 1,200 reviews.
