esd(electrostatic discharge): static electricity or power surge will damage the led. use of a conductive wrist band or anti-electrosatic glove is recommended when handing these led. all devices, equipment and machinery must be properly grounded. (a) recommended circuit. (b) the difference of brightness between led could be found due to the vf-if characteristics of led. cleaning: use alcohol-based cleaning solvents such as isopropyl alcohol to clean the led. precautions for use: storage time: 1.the operation of temperatures and rh are : 5 R
1.t.sol=235 R R R 120 seconds max temp. maintain above 183 time within 5 R ~ 25 ~ 55 ~ 25 R RR
