Lumatek ats pro 310 watt running hot.

[George P.]

Update, i have had this light for 18 days, the temperature that rises inside the tent is 42-44.5f above the temp of the house but 4 times it raised it by 50f without changing the ambient temp, now i have 86f inside the tent and 68f at home.
The driver is so hot that i cant touch it for more than 30 seconds.
All the professionals say that this is not normal and is due to a broken driver, also people say that this particular light is quite cool, something that contrast with what i see.
My exhaust fan is at 150cfm which is fine, the problem seems to be at the driver.

You think it's running hot. Pros tell you it's running hot, has a defective power supply, with it normally running cool. What's going to happen when it sooner or later fails for real? Electrical fire? [I wouldn't run it continuous in such a small flammable plastic tent].

It sounds like simply opening the tent might work for temperature control and ventilation. Have you tried this? [Running with fresh air from an open window in another room and not complaining about the cold - are you in the tropics of S. hemisphere?]

Put a small fan on your light to help dissipate heat and help it last longer.....vent hot air out the top of tent and let cool air come in passively at the bottom.

when i told lumatek that the driver is very hot and i can't touch it after 30sec they told me it needs to be replaced and the same day they gave me a new one without checking the defective, that is super convenient if you don't have a second light.
As far for the new led the temps i have are similar, something that i had been warned from the company, with the old i had 78-86f and with this i have 79-84f. It's not the temps inside tent that determines a defective unit, they told me, but if you can touch the driver or not.
The driver at first day was very hot, i could touch it but with difficulty, at next two days, although the temp climb up by 35f the driver was cooler and It was more comfortable to the touch, weird things.
They suggest to upgrade to a 3.3x3.3 tent and also bigger exhaust fan, which is sound logical, but i'm a little worried if i would see a significant drop at temps.
As for the size of exhaust fan i asked 8 companies and they all gave me different answers haha. So far based from what they've told me for a 3.3x3.3 tent i need something between 117-412cfm
I thing 260cfm, with speed controller of course, will be ok to to cope with the high temperatures of greece.

I have done that, i put a 15w fan blow at the driver but it didn't work, temps are the same. I'm also using an inline fan to bring cool air.

I want to ask something else, does the fabric of the tent play a role in temperatures? I currently use a tent with 600d fabric, if I buy a tent with 1680d, is there a chance that the temperature will rise due to the better insulation? Also, I read that tents with white lining are cooler by 7c than tents with silver (mylar) lining, is there anyone who can confirm this?

Regarding: "They suggest to upgrade to a 3.3x3.3 tent and also bigger exhaust fan, which is sound logical, but i'm a little worried if i would see a significant drop at temps."

Your problem could be that you simply have no temperature control. Blowing/sucking outside air in or out full time is not temp. control!

If you use a simple thermostat switch/outlet (with it or its sensor in the tent) to control your exhaust fan (and related sucking in of cooler air) there simply will be no "significant drops" in tent temperature. If your outside/source air is too warm to cool your tent, you simply have no choice but to cool your input air, need to use an air conditioner. Although usually costing about $25, thermostat switches (with most also having on/off timers) can be rather cheap, such as https://www.walmart.com/ip/Thermost...ol-Plug-Smart-Temp-Home-Greenhouse/9333800776

Thank you for your interesting. I'm planning to buy an exhaust fan with temperature controller. My ambient home temp is at 68f so i would expect a temp of 78f inside tent not 80-84f that i have now.
From another forum a guy told me that with the same led model he has 64f ambient temp and 68f inside tent, this is a big difference with the temps i have.

You may not need to buy a new fan with built-in controller. Your current or other exhaust fan with a thermostat patched in will do the same thing.

If your external/source air is constantly around 68˚F, just blowing/sucking that air into your tent area and opening the tent flaps may work well for temp. control. And if you're moving enough air in/out of the room, with such as small tent, presumably growing just 1 plant, exhaust air will be so diluted you don't need to bother to filter your exhaust.

Well, i will upgrade the tent to a 3.3x3.3 so i need a bigger exhaust fan that what i have. As for the flaps i can only open one because tent is in the corner, i did that and it didn't help much. I have two autos in the flowering stage and they smell so i need a filter.
