If you don't know what kind of light bulb you have, it can be hard to figure out what kind of shape or size you need to replace it. Especially older bulbs with dated styles, it can be hard to figure out what the size, shape, style, brand, base and technology of your bulb is without a label or an easy reference. Worse, so many bulbs just have cryptic codes on the base, where googling won't return results.
You can upload a picture of your light bulb using the form below. The picture must be a valid image file. It should just show the light bulb on a plain background.
Whatsthatbulb is powered by a convolutional neural network trained on over thirty different categories of light bulbs. This is a new kind of machine learning called "deep learning" which is starting to approach human performance in image recognition problems.
