Default Re: Old Drydex Torch with Replica No 8 Battery and LED.

No resistor. Those LEDs should have 3.4V so even with fresh alkaline cells it's below that. The rated current is 150mA but even at a fifth of that it gives well over half the light it would at full power; it's certainly as bright as a tungsten lamp would be.
