I have that same kind (not purchased from KD though) and I don’t see a difference in any I’ve had.
Do you mean you’ve had both types? The 5mm lights and the 10mm lights and there’s no difference?
i have both, but not from dx, the second ones are definitely a lot brighter (x2-x3)
i got both fron DX the 10mm ones were rubbish see post in this section
10mm led from DX not recomended
cheers Barrie
You should go with the Nichia branded ones.
I've have Both .... 10mm and 5mm
My 10mm appears to be "slightly" brighter .... BUT the light color is a Blue / Purple tint and I can change the battery (I think it is a 2032 button type)
My 5mm is WHITE. cannot change battery throw away type.
