Noodles,
distances between bulb and fresnel, also between fresnel and objective, are essential parameters of a lighting setup. You must built any case around this. Decreasing distance bulb - fresnel would not only increase heat, it also would enlarge collimated beam towards the objective, which would cause not all the light to reach the objective.
