I like that the updayday light bars rotate but don’t have one, yet

At first I thought It was a stupid gimmick. But now thinking it would be useful in my 2x4. I could tilt the 2 outside bars in as I'm not using the full 4x4 they recommend. Sound legit? or would it just fry that section of canopy?

For the people asking about light intensity on the canopy... I use the lux light meter app on my android phone to get a pretty good idea of the light intensity distribution on my canopy.

It's def not as good as having a $500 par meter, but it gives me a pretty good idea of whats going on. The numbers it reads out depend on the internal hardware on the phone, so different phones may read out different numbers for the same intensity. I gauge it off of a known good intensity level from a known light.

As measured on my phone, I try to be at 5000lux for clone, 10000lux early veg, 20000-30000lux full veg, and up to 50000lux for full flower intensity.

Anyway, it should reveal the differences in intensities distributed across your canopy.

How much heat that put out in a 3x3? Any struggles? Can I ask your air flow details?.. sorry but I'm dealing with some 90F+ in my 2x5 with my new 400w updayday.. curious if that's why light was so cheap haha

The 3x3 is averaging 75 degrees while the light running at 50% 18 hours a day. Ambient room temp is ~70 degrees. My current airflow is on the lower end, with a 90 CFM exhaust and some fans zip-tied to the tent-poles. If I ran the light any harder, I would replace the current exhaust.

I'm sure you can figure out a solution with your current light.

A 400w light makes 400w of heat regardless of the manufacturer. The amount of heat introduced into the volume is equivalent to the power drawn into the volume. If you can get a light that allows you to mount the power driver outside of the tent, that will help.
