-		Make sure your setup can handle driving both white channels at maximum output simultaneously. This results in a higher heat output and might reduce the lifetime of your LEDs.

+!!! warning "Additive Blending May Cause Heatup"
+	Make sure your setup can handle driving both white channels at maximum output simultaneously. This results in a higher heat output and might reduce the lifetime of your LEDs. For example, bulbs by Athom are designed for linear blending (0%) and may be damaged by attempting to use additive blending.
 
 You can limit the maximum allowed additive blending at build time using the `WLED_MAX_CCT_BLEND` macro.  
 For example, add `-D WLED_MAX_CCT_BLEND=0` to your build flags to force linear blending only.
