Your friend is right, higher temps for led growing are ok. 28-30°C is a good environment for plants under leds, keep an eye on the humidity.

The range mentioned by Koondense is exactly where you will see peak performance. Light intensity, temperature and photosynthesis are very entangled, if it's 70 F and the plants see 1000 PPFD, that's a bigger problem than if they see 600 PPFD
It is better to keep temp around 30C. Cannabis love this temp.
Watts are watts in regards to heat radiated by light fixtures. The heat comes from the bulb and the ballast with HID. The heat from LED’s is largely from the drivers, with LED’s themselves adding the rest. Still, if you run 500W HID, or 500W LED, heat output remains same. Good discussion.Please keep in mind the fact most leds are wavelength limited to around 700nm,some go to 760nm. Meaning there is very low IR radiant heat so the ambient temps need to compensate for the lack of IR which is abundant in sunlight and most hid lights.
