Product review (5 stars): The LED upgrade bulb is  E12 White bulb 64 3014 SMD LED lamp 110~120v 2.6W Silicone Crystal small
It works great so far. It came well packaged and timely with prime shipping. No damage. On its coldest setting using a digital thermometer I found it would cool down to 36 degrees, the compressor would then kick back on and cool once it reached a temp of 42-46 degrees. Yes it does have a compressor like is on a dorm fridge and is just as quiet. You can also easily upgrade the light bulb to an led. I used an e12 base led that's works great and is a cool white color. The only place I found an led bright enough and small enough was on a popular auction site shipped from china. The search for the led bulb is the title of my review.
