Package Dimensions (Unit: mm):
U325 Series-2525/60 Degree/Adhesive Quartz glass ball
Note:The polarity of the UV LED pacakged by the hole board chip is opposite to that of the normal vertical chip!
U225 Series-2525/45degree/Adhesive Quartz glass ball ;U425 Series-2525/90degree/Adhesive Quartz glass ball
Color consistency compared with other vendors' products:
Due to chip packaging differences,UVLED chips on the market emit different colors of light visible to the naked eye when lit up,Such as yellow, blue and purple.The shorter the band, the more pronounced the phenomenon.

There is no direct relationship between color difference and curing effect,But it will affect the human body's senses and the appearance level of the product,And color consistency is not good.At present, BYTECH package scheme can solve this problem.
