Hi,
Please check out this photo - https://drive.google.com/open?id=1rCAZW ... 6DRz3Ftebb
Based on the photo, both are water clear, but there are significant difference between the blue light produced by both the LEDs. The left one is brighter than the right one. Also, I noticed that the tip of the left LED is somehow oval (?). May I know what type of LED the LEFT one belongs to? And does Cytron is selling any of this type of LED?
