Parabolic bulbs are recommended for those with heat issues. This is due to the lamp being mounted vertically so that heat intensity will rise to though the top of the reflector as apposed to a conventional horizontal reflector where the light and heat is being directed towards the plant.
This allows the light to be reflected onto the plants rather than being directly aimed at them, this seems to be more effective than traditional horizontal reflector lighting and result in both better yields and healthier plants.
