For only 60 cents in our neighboorhood chinatown, you
Can now have a plus 100 lumen light for your powerbank.
As seen in the picture, it uses 5720 leds with 330ohm
Resistor each. Since this is retail, maybe an online store
Offers this in a cheaper cost?

I really suck at posting pics :( just check my prof pic so you can see

haha nah facebook won’t let you post facebook uploaded pics elsewhere
that’s why your pics won’t show up no matter what

I have used one of those usb lights and they heated up really fast. It held on for hours but the heat got me worried.
