Manual Handling

Use tweezers to grab XLamp MT Family or MK Family LeDs at the base. Do not touch the lens with the tweezers. Do not touch the lens 

with fingers. Do not push on the lens.

Do not apply more than 1000 g of shear force directly onto the lens. excessive force on the lens could damage the LeD.

Cree recommends the following at all times when handling XLamp MT Family or MK Family LeDs or assemblies containing these LeDs:

• 

Avoid putting mechanical stress on the LeD lens.

• 

Never touch the optical surface with fingers or sharp objects. The LED lens surface could be soiled or damaged, which would affect 

the optical performance of the LeD.

• 

Cree recommends always handling XLamp MT Family or MK Family LeDs with appropriate eSD grounding.

• 

Cree recommends handling XLamp MT Family or MK Family LeDs wearing clean, lint-free gloves.
