LED is seen as the light source of the future, but it really is still a light source under development. Young Shield Limited tests all new light sources and quickly adopts them into the product range once they have been found suitable. Close correlation exists between the light source and the products featuring the light source. In short, the relationship between the light source, the product and applicability must be relevant. Power Light Tech Limited invests a great deal of care in choosing light sources for the products, anchored in the company product philosophy.
