The Difference Between Steam and Condensation for LED Lights


Difference between steam and condensation:

Some of our customers have inquired on the best method to differentiate the difference between steam and condensation.

Steam occurs in virtually all lighting applications, due to the difference in temperature in the LED lamp housing and the temperature outside. As the temperature cools down during the night or during cold weather, it creates a temperature discrepancy between the outer cooler air and the warm air inside the LED housing.

Steam is more noticeable during the night and will resolve itself as the temperature inside and outside of the LED housing have less of a varying difference. If you see steam inside of your LED housing, this is a common occurrence and does not affect the product in any way. Steam will alleviate itself as the temperature inside and outside of the housing stabilizes so this is not a cause for concern.


Condensation is a more serious issue. Condensation occurs when there is a crack or an opening that allows water to get inside of the housing. Some fog lamp housings have a small moisture cap that could be jostled during wear-and-tear and cause some water leakage during car washes or rain. If that's the case, you can try to remove the water condensation by detaching the housing and running a blow dryer or leaving the assembly at a warm and dry location.

If you don't want to proceed with troubleshooting, you may contact our customer service team and they will assist in helping you resolve this issue.
