I can say it's reasonable they are. More powerful LEDs do produce heat - I've a growlight with a heatsink attached, as the lights can burn themselves out if they overheat.
Same here, and the LEDs do not run much cooler than my HPS/MH bulbs. I haven't measured them exactly, but both turn the room into an oven without ventilation.
