Nope! Vont Smart Bulb Pro is ETL certified, which includes a safety test for temperature. Although they will get warm during operation (though they're much cooler than incandescent bulbs), we recommend turning your Vont Bulb off and giving it a few minutes to cool down before handling.
If you absolutely need to touch the bulb while it's on, make sure to grab the top plastic part (where the light comes out) instead of the metal heat sink.
Also, a quick reminder to not use your Vont Smart Bulb in a fully enclosed light fixture, so you can avoid overheating and boost its life span. 😉
