Product never arrived!!! seller didn’t refund my money and didn’t respond to my messages! people do not buy from this seller!!!
Good. Battery box has a 10 ohm resistor in it, all leds in parallel, forward voltage of diodes about 3v as you would expect, draws 150mA. Wire is stiff, so can be bent in to shape rather than "draped". Note that at least for 5 and 10M (I did not buy 2M) the resistor is 10 Ohm, so 5m is brighter than 10m, I think resistor should be increased to 20 Ohm in 5m version for double life.
