But I’m unable to design the circuit for it. Shenzhen Ledodm Lighting Co. Contents 1 Using a Cellphone Li-ion Cell 1. You can use it during blackouts, while camping, doing videoshoots, doing photography and other stuff Bottom line, never use this setup at its max, only tune it at half the brightness. You may also want to connect a current limiting resistor on each set of three and attach the chip set LED heat sinks to a big heat sink to have a longer lifetime. This helps ensure uniform light distribution or emission from the LEDs.
