Hey! You can use a special lamp like an LED smart light desk lamp inside of a box to provide the same efficiency friend has this lamp for the same purposes, and I can say that this device works perfectly and has a wide range of color-changing options. If you are looking for a cheaper version, I can recommend you buy the smart bulb from the Vont brand. The two-pack of those will cost you only around 15$. Reach me in PM if you are interested. I will share with you the site where I usually buy them.
