OK, bright and hot are relative terms. The output of the 1200 watt Continuos Wave Xenon bulb does put out heat, but it is dissipated well by the use of a single output fan, of the same type you see on the NuArc 26-1k series. I worked with a NuArc 26-1k for several years and based on that experience I do not believe there is much difference in heat build-up between the ULF-28 and the NuArc 26-1k. In fact, probably less with the ULF-28 than with the NuArc. Bright it definitley is, but there is a curtain that draws around the unit to protect one from the UV light so in use one sees very little light.
