If you, your boyfriend, girlfriend, dad, and/or significant other played any of the old Nintendo Zelda games, then they'll know exactly what this is. This is the 8 bit symbol for life power or health. This is my own design and I 3D print these to order at my shop  on Etsy. https://www.etsy.com/listing/265502464/8-bit-heart-led-touch-light-inspired-by?ref=shop_home_active_20

As for details, this is an LED touch light. All you do to turn it on is gently press down on the power symbol and listen for a click to activate or turn off the light. The 3D printed 8 bit heart is made out of red PETG T-glase which has great optical properties for this design.
