Hey I'm not sure you read the posts completely before you started to defend your 250w no heat problems. The comparison is the 320w LED fixture to 400w MH. This fixture is rated beyond 250w MH's, so it was not even mentioned. There is no such thing as a 400w MH that doesn't give off excessive heat. I have ran both 250 and 400 MH fixtures for years....and yes I did not have any issues with the 250w.
Also when LEd's are rated for Wattage thats usually everything at 100%. You can run that fixture at whatever power rating you want by ramping up/down power or changing the spectrum. The MH fixture is either on or off. That is it and it the 400w is more like 440 depending on bulb and ballast. I'm just pointing this out, but would take a whole article to explain the power ratings and usage of lights. there are articles on the forum that go over some of the details.
Im excited to see how this thing compares.
