I have a hunch that the V3's will be released this year...

You mean something besides the Diablo boards? My guess is the 648 is the new 288 since they are the same exact board size and cover same footprint.

I would definitely grab that 600W now while its still in stock!
 
So - the final decider is going to be the heat output. I have 2 8" fans going so air movement isn't an issue. The lights I have currently are cooking my plants.

Will this reduce the heat down into the low 80's?? If not, what benefit will I gain from the light?

Hard to say exactly without knowing some more details.

Remote mounting the driver outside of your tent will help shave off a few degrees. Can you mount the new driver outside the tent (and preferably another room besides the one the tent is in)?

What specific lights are you using now?

Where does your exhaust vent to?

No matter how much air you move, that light appears to be too close to the top of the plant. It looks like you grow "au natural". You should read up on topping and low stress straining and canopy management before you set up your new lights ... your investment will be much more productive if you have an even canopy.

Interesting tent. What is the footprint? Considering the design of that lamp, you may have some serious hotspots if you can't hang it high enough.

Yes, definitely working on canopy control.

Going towards sog, will have a lot more control over the height of the light, hence canopy coolness. Learning a ton of info from all you guys, thank you so very much for the constructive comments!

So, I love the idea of those lights. Would love to drop $800 to buy them, but it sounds like I still have some learning to do before I invest that much $ ? Maybe I'm just overly cautious.

I do have the option of turning the "veg" switch off on the lights, which i did. Figure better than cooking them.

Tent is a 4 x 8, but floweing footprint currently is 4x5. Equipment etc fans taking up the other 3 feet. This is the ultimate goal. Wondering if I should ditch the table.period and just grow on the tent floor in the 1020 trays...

Hey @Nefrella , what do you have for inline fans, one AC Infinity Cloudline T8 and one Cloudline S8? Are they hooked up to the same controller?

Are you using both fans for exhaust purposes with a passive intake? Or are you using one of the Cloudline fans for your intake? And as @ilovereggae asked where do you vent your exhaust to (same room, different room, or outside)?

This issue should be easily remedied. What is the ambient temperature of the room that your tent is in?

Currently using Sunraise2000w (400w)equivalent. Run at 3.21 amps each (this is with both the veg/bloom switches on, will have to check tonight to see what it runs at with bloom only), so a little under the 400 mark.

Exhaust is venting to the outdoors, intake is just the normal apartment air, which is obviously not an ambient 86 degrees.

Yes, the infinity fans are hooked up to the same controller. One is exhaust, in is intake. Should i take one off and run it separately? Seems to work well for the pos/neg pressure.

Ambient temps are low 80s on a normal day, mid/upper hot days (ac gets turned on) so never above 82 deg.

You really shouldn’t have any issues with that light in that space, with those fans. I had no in flow fan in a 4x4 running 720 watts, and just a 6” hyperfan and it kept kept tempts around 82. At worst you could look into strips if it worries you that much.
 
i notice your fan is pointing up. that will help to heat up the room a tad but all these things are "minor" compared to the heat from the lights. going from 400 watts to 600 will up the heat a tiny bit more. Maybe im reading wrong and your running an actual 800 ish? In that case your temps may go down slightly. The light your wanting to buy vs the ones you have are not much efficiency difference. WAY better light but its not gonna be THAT much more efficient then what you already have. (overall , yes its going to be way better but in terms of heat only , they are really close to the same. )

watts and heat go hand in hand. 1000 watt light and a 1000 watt heater are pretty similar. The light you want is spread out a lot better so the 600 watts is spread across all those chips vs the one you have being tiny. Thats going to make the one you have feel much hotter to the touch.

Thank you for the very frank comparison - much appreciated. And yes, running closer to 800W as there are two of these in the tent.
