LR (lower ohms) will provide a
warmer vape. The coils get hotter and get hotter faster than a standard or high resistance coil. They also will draw more power from the battery to achieve this. LR will not have the voltage range that a standard or high resistance coil will, as shown in the Safe Vaping Power Chart below.
LR cartos were originally designed for single voltage mechanical mods to simulate high voltage vaping like a regulated (VV/VW) mod can give.
Standard resistance coils can be used at a higher voltage than low resistance coils, and will draw less power from the battery doing so. These provide a
cooler vaping experience.
High resistance coils (2.5 - 3.0 ohm) have an even larger voltage range for regulated mods (VV/VW), and can do so with even less power from the battery. These also provide for a
cooler vape.
Lower resistance coils means electricity flows with less resistance from the battery to the coil, thus more energy (more power) is pulled from the battery. Higher resistance coils means electricity flows with more resistance to the coil, thus less energy (less power) is pulled from the battery. This is a commonly misunderstood concept. Batteries don't "work" harder with either resistance; a battery will freely give whatever energy (power) it has. The resistance determines how much of that energy is actually used by the coil.
Think of electricity as the flow of electrons. A low resistance coil is like a wide open door where a large group of people (electrons) can go through the door at once. A higher resistance coil is like a narrow door where only a few people (electrons) are allowed through the door at one time.
