because of the efficiency the will be less heat, but how much we don't know.. I do know the luxton stars get so hot they need a heat shield to prevent the LED from burning out and I can only imagine that a 5 watt version would need that also sense a 1 watt version does. so there will be heat thrown out. now sense they use 40% less energy then you are looking at a heat difference of 40% (at least) but how much of this was through the ballast? I would say 1/2 sense I know how hot my ballast get. light is radiation of energy which when comes in contact with a surface will change to heat, the question is how much. weather you have 250 watts of radiant light from a MH or 250 watts of radiant light from and LED it is still the same amount of energy (assuming 100% efficiency) and will have the exact warming effect. now I am only taking about the radiant component, not the convection or conduction types. Convection is the big one that we have a problem with in closed hoods but can be solved with power venting, but you can vent all you want and Radiant heating will not be affected.
so like I said before.. will it run cooler, probably... how much... don't know.
