How much heat will a 600w LED ADD to a 5x10x7 grow space

How much heat will a 600w LED ADD to a 5x10x7 grow tent?
Say if the room (before adding a light) is a steady 65f degrees with just enough air exchange to maintain negative pressure, how much added heat will a quality LED add to the environment?

Starting a new grow room and trying to figure everything out beforehand...
Thanks!

Temp probably goes up to around 72F with good circulation inside. You'll need about double that for the space though.

with 65f temps wouldn't it be a better and cheaper alternative to use an HPS and not have to heat the room? Just curious, as I believe proper leaf temps for LED would be 80s.

Thanks, only going to grow in 1/2 the area, - so, sounds like it'll raise it about 5*

That is a good idea no doubt - but I've got to be sure i can control the heat (not let it get out-of-hand) in the area it occupies

will the temp fluctuate with seasonal weather? Or is it a basement type setup with cooler temps year round?

Is this 600W from the wall, or a 120W LED that has marketing that puts it at 600?

There's a huge difference.

645w from the wall

basement type set-up with about 5-7 degree maximum fluctuation year around

the literature from the LED manufacture --- " operating temperatures range between 25°C (77°F) and 30°C (86°F) above ambient air temperature"

So the led will be approximately 150*

Also make sure you pull in fresh air from outside or another room otherwise the heat will build up.
