A pillar of Cor 10 steel was welded together using 3"x3" cells with tear drop holes to allow light to pass through. This tower has a weathered patina and then clear coated. The light inside is a LED strip strung along a 2" square tube. The cord has a port in the back to easily connect and disconnect. If the LED strip ever fails then the light tower surround comes off the base with just a little vertical pressure.
