Too much heat! P600 Platinum light, 2 x 4 space

I have a P600 Platinum light in a 2 x 4 grow tent with an exterior portable AC blowing in cold air and a carbon filter sucking hot air out from top. It was perfect when I had my light only on VEG. But now that I'm flowering, I put VEG and FLOWER buttons on. Ever since, my temperatures have been rising over 28C. Today I look it has reached 32C! I'm over a week into flowering, and I was wondering if it were possible to switch the light intensity back into VEG, or would the color spectrum be a problem?

I'm not trying to switch it back to veg, just have only the VEG button on and still keep it for 12/12

With the VEG and BLOOM buttons, power is about 450W, and the color is red. VEG button alone is about 200W and color is bright purple.

Just wondering if it would be ok to only use the VEG button for flowering

Probably would lack proper PPFD for flower. Spectrum is less important than intensity/photosynthetic photon flux. You should ditch the piece of shit blurple panel LED and get QBs, COBs, or EB Strips in 3500k, 80 or 90 CRI ASAP. I mean no offense, I am simply trying to help.

Where are you taking your temps?
Take a temp reading under a leaf near top.
Don't take a temp reading directly under the light.
I wish I could get 28c lol that's a good temp.
I don't think you'll have enough watts with just the veg switch on in that area.
How high is the light from the plants?

So let me ask you this...

If there's a veg and a bloom setting.

And you're in bloom.

Why would you choose to only use the veg setting, instead of only the bloom setting?

I think by running less watts the temps are easier to control.
Veg only 200w
Bloom only 250w
Both switches on 450w

You got a serious problem then. I ran well over 400 watts of t5 in a 2x4 and stayed cool with no a.c..

How do you have the ac hooked to it and what are you doing with the exhaust?

Have you checked that the light's cooling fans turn on, when you switch it over to bloom?
Do all the diodes turn on?
It doesnt make sense, to get that hot, after only another 200watts.
Im sure you're losing energy, as heat, somewhere.
Having said though. I have a vipar900 reflector series. Think its 480watts on full spectrum. It runs HOT.
Hotter than my 600hps in a cooltube.
28'C aint all that bad. 25-26, would be fantastic. But 28 aint gonna make a massive difference.
I get nervous in the summer here. My canopy can get upwards of 32'C for short periods. TBH, iv'e only ever, had one plant reach for the sky, foxtail, and fluff right out. It was sativa dominant, and still smoked great.
It's never caused me any hermies either.
Imho, just do what ya gotta do. Grow, dont buy.

Just like a Vipar ... Dual stage switches ... For you to get anything worth growing BOTH switches must be on. Using single channel lighting deprives the plant ( stretchy , lanky performance ).

That is the most common issue I see with those running VEG / BLOOM panels.
As stated by others , shitty diodes are what they use ( bridgelux / epistar ) , they are purposely under driven ( to extend life ) , bad Heatsinks and TIM ( most have a 1/8" fin ) , inefficient drivers which all play into the performance.

I took apart a Mars and seen the THIN heatsink and white toothpaste TIM used.
The heat led to the demise of its IR chips , they burned out ( lens melted ).
Panel scrapped.

As far as heat , perhaps a dedicated fan blowing across panel would help exhaust the heat better. I really had to up the exhaust inline fan when I used to those kind of lights.

I tore my 600w vipar apart to convert to 561C boards.

This is what the vipar board looked like after one grow. Quality eh?

Geeeeezzz. Lolz
You LED users are so damn vain.
Instead of trolling, why dont you help the OP use the light they have?
I believe that was the problem for posting here?
You guys are like a bunch of butt hurt teens.
Get over yourselves, and your damn LED's.
Help the person. Dont flame them.
Makes you sound ignorant, and stupid.
He / she, ain't gonna go and buy a new light just for you.
So help.

If its too hot then you should try and figure out a way to cool it down. you need your red colored spectrum for better buds. the veg part of your light is lower on watts, and has more blue light then red. Maybe you can try and ventalte a little better. figure something out because you'll have more issues down the road if you don't. Heat stress is real.
