Hi All
Is it possible to drive a light from external power supply instead of a battery ?
A friend of mine wants to put a diving light in his store and let it power on for 8-10 hours
The diving light have one 18650 battery and the power consumption is 2 - 2.2A
I tried an external power supply 5V 2A but the the performance was very low
I tried PC power supply 5V 15A but also in very low performance
Last I tried a adjustable power supply 0-30V 3A and it worked in high performance but
after 10sec the led and one resistor ftom the power supply ftied
Any idea why this happend, is it possible to power the light ftom an external power supply
Thanks in Advence
