Not yet, but they are def hot
Yes they are already burned my plants once and made my T5 too hot to use in my tent even at the max height lol........... IMHO these bulbs are better suited to more open spaces and not tents...........

To be fair though you are just running your heat in a circle and hid would be even hotter.

You have to get that heat outside the house somehow.

Well i cant speak for the agromax bulbs themselves, but I can say my plants have responded positively to the addition of 15k blue, I noticed and big increase of trichome coverage within days after adding it. And the finished product seemed better as well. I'm definitely going to keep using it.

Is it the operating temperature of the lamp, or the intensity of the UV output that's burning plants?
I agree, these bulbs are not for noob's fo sur
He is blowing the heat into the room with the tent and trying to cool it with an ac.

I advised that the heat has to be exhausted out of the house.

I did the same thing and once I exhausted outside my cab dropped by ten degrees.

Even with cool temps I have to be careful. Its not heat burn but radiant burn?

tis the UV, it is just like bein in the sun, you can def feel it on your skin, even several feet away
Something I just read in checking out that bulb was it suggested a 3' distance and only running it for 15 minutes every hour for the first 4 hours lights are on. A starting point at least.

Depending on maturity of the plant, intensity can stunt or burn the plant. The duraplast, chloroplast, and epidural layers need to be developed to handle more intense light. T5 is the beginner to pro light typically used for young plants like, seedling and cuts. Other than that the strain could be sensitive to the intensity. MrNice guy is said to grow better in a shady environment. Some growers perpetual harvest plants throughout the summer. The final buds cut are usually kept by the growers because of the higher terpene content and such.

I know you recommend that, but I also have a portable A/C in the room and my 3x3 tent with the 315w LEC CMH is not burning my plants with temps in the same range as the 2x4 was when the T5 was in there. So that doesn't make sense...................

Also figured out a way around exhausting out of the room with dryer hoses, I just leave the door open and the air is exchanged with the rest of the upstairs and the house A/C is running as well.

So while people can insinuate it's me, if it was both of my tents would be screwed and that's not the case. The T5 tent was the only one messing up my plants. I put the 4 COB LED back in there same setup in the entire room everywhere else and temps dropped and the plants new growth is not all messed up like before.

IMHO, a 4 bulb T5 would have been better suited for this "enclosed" space and the 8 bulb is just too much...........

Yea 315 watts vs 432. Big difference.

Exhausting in the same room as the tent or even in the house is a bad idea.

Your heating the room and then trying to cool it.

Trust me. You step up to a 400 hid or bigger you will have the same problem.

Exhaust out of the house. You will thank me.

I am in no way trying to argue brother, but the current facts are the facts. And FYI the 315w LEC is rated to perform like a 400 HID with less heat and power draw hence the reason I bought it lol.......

It doesn't matter what you run.

It would be wise to exchange air.

That means to get rid of it and bring new in.

I'm running the same eight bulbs in the same size space at about 8-10 inch above the canopy.

My temps never get above 82.

Its not the t5. It is improper ventilation.

I'm not going to argue either.

Fact is to run exhaust in a loop is wrong. For more reasons than just heat.
