For each LED Lamp
Color Red, Green, Blue
Note:
1. The LED B/L of “triple color” is designed for voltage driving, user have to follow
The drive voltage that can make driving current in safety range (current between
minimum and maximum).
2. owing to having 3 chips in one LED lamp, which caused many combinations of
different wave length. This situation will caused wave length shifting while driving
2 colors or more in the same time.
3. The luminous intensity is measured on B/L surface only.
