Admittedly, I was looking for something like these for modding.
But at $18 for 2?? nah. I am not willing paying much more than $2 for one of these.
The another problem of these cheapo lamps is that they use a resistor to “regulate” the currents, and boy these resistor dissipates just as much (if not more) heat than the LEDs itself.
This drains the extra voltage to the “wrong” place and make the battery life situation even worse.
