I've made my own light, got a 400 watt metal halide light that they use on car parks etc, made a wooden stand for it and wired it up with some of that arctic flex, absolutely by far the best ever plastering light i have ever seen or used, it gives off a very bright white light, I've just done a lounge in a barn conversion, 28'x14' this one light in the corner lit the whole room up a treat, never had to move it. Bulbs are a bit pricey but it takes a knock ok, I've twatted it a few times now and it hasn't bothered it so far. I would post a picture but i don't know how........
