Do not stack PCBs or assemblies containing XLamp XR family LEDs so that anything rests on the XLamp LED lens. Force applied to the 
XLamp LED lens may result in the lens being knocked off. PCBs or assemblies containing XLamp XR family LEDs should be stacked in a 
way to allow at least 1 cm clearance above the LED lens.

Do not use bubble wrap directly on top of XLamp XR family LEDs. Force from the bubble wrap can potentially damage the LED.
