I was looking a bar of lights for my tower. I live in Canada so all those sites like wakeside.com and buywake.com are in USD for me. A bar of like 5 or 7 lights, around 35 to 55 watts was like 500+ US dollars. That'll cost me around 700 canadian pesos.
anyway, i could just go to a local hardware or tuck supply and pick up some 100watt driving lights and mount them on my tower for 40 canadian dollars per light. seems obvious to me!
