Condensation in your Lights- Sanmak Lighting

Condensation is a naturally occurring condition that can affect any light. It does not suggest a defect in a product, as opposed to what happens when a leak occurs, in which case there is water ingress that could lead to a system failure. The explanation contained herein is intended to help end users differentiate between these two conditions so they understand what, if anything, needs to be done.



Condensation is the change of water from a gaseous form (vapor) into liquid water. It appears as small droplets of moisture inside the light. Condensation does not cause a problem with normal operation of the light and is, therefore, NOT considered to be a defect or warrant-able condition. In fact, Sanmak LED Lights are designed to allow moisture to escape and not reenter, but it takes time for the moisture to evaporate (the amount of time will depend upon whether or not the light is turned on or not).

Water Ingress

Water ingress describes water that leaks into the light, manifesting itself as large droplets and pooling of water that is clearly visible. Sources of water ingress can vary. If a light suffers water ingress as the result of physical abuse and/or misuse, it would not constitute a manufacturing defect. Otherwise, water ingress caused by a defect in workmanship is a warrant-able item. In this event, please contact the dealer who supplied the product to schedule a return.


As a matter of fact, all lights( include led work light,led light bars, led headlight, led driving light, led warning light, led signal light, led interior light etc. ) are prone to condensate due to the following events:

1. Plastic parts used in lights naturally absorb moisture in the air

2. Air is trapped inside a lamp when manufactured

3. Moisture attaches itself to the coolest part of the lamp, for example the lens

4. As the light heats up these plastics parts release moisture that mixes with air

5. LED lights produce less heat so moisture takes longer to evaporate, so it can be more noticeable
