Thunderhead Stainless Steel 316L round wire in various lengths and thicknesses.

Stainless Steel has the lowest resistance of the three main wire types stocked at eLight. Lower resistance means you can get large weighty builds carrying a lot of power with even plain round wire. However, this lower resistance also means that complex builds may end up too low resistance to fire on your regulated device (usual cut-off point is 0.10 ohms). SS316L also has the highest ohm fluctuation under heat of the big three, which makes it the only wire type that supports both temperature control and wattage modes. 

Thunderhead spools measure 5cm in diameter and have two slots and four holes to easily tie off your loose wire ends.
