Although I doubt you'll be running them at max power for any length of time (at least I hope not), let's do some numbers anyway just for grins:

at max power of 251 watts, the 550-12 generates 267 watts of waste heat.

at the same power output of 251 watts, the 775-18 generates only 141 watts of waste heat.

the mass of the 550-12 is 218 grams. the mass of the 775-18 is 337 grams.

the ratio of waste heat to mass is therefore

550-12: 267/218 = 1.22

775-18: 141/337 = 0.42
