Does the ballast get hot? Like... too hot for a closet with no exhaust?

You mean driver?

yes, the top piece, the guts, the dimmer box and everything aside from the leds and their metal tubes

Well ballast are similar. But no tomatoes lol

how about spilling some of your guts and make some sense of this

i have a bestVA3000 blurple led light... its rated as a replacement for a 1000w HPS. (rated by a non-Chinese reputable source.)

I have one large Romulan plant in my closet with no exhaust or ducting or filters or scrubbers or anything. Plants doing fine, not yielding as I hoped but the only heat is from the LED bulbs and the glass panel that separates them from the tops of the plants. The light has several fans on top, which seem to be doing little, although I am having no heat issues which is why I purchased it. my setup is so simple its almost ridiculous

I'm going to be paying attention and experimenting with light variables but if I can update the light for something with more power and a better spectrum I would like to do so, unless there's more heat.

I am most worried about heat issues with this FC 3000. Please correct me if I'm wrong.

More watts mean more power means more energy means more heat. That’s the laws of physics.

Well.. my light is rated as a replacement for a 1000watt hps.... and its certainly cooler... I remember my HPS days and cutting holes in walls and using aluminum ducting.... I cant tell how the yield is yet, my plants only on day 34.... but so far its certainly a better setup and a lot less work. I just don't know a whole lot about LEDs. The rating seems pretty damn good if its a genuine replacement for the HPS... but lots of people on here knock blurples and maintain that these newer LED bars put out a better spectrum.

So back to the heat. That's why I have what I have. I want to know if I switch if there's going to be more heat..

Your led is equivalent to 1000 watt in light absorption by the plants because hps have a much higher inferred. Which makes it much hotter on the plants. Like a 100w led is to match 250 watt hps.

I understand my friend.... but I'm trying to talk in reasonablys, approximates, etc. I cant see how this LED is equivalent to a 1000hps but I trust the source it came from.... its so damn cool in my closet though. I have a small plastic fan going and it barely does anything... the only real heat is 1-6 inches below the light.

I have heard some of these bar-LEDs with the (drivers) get hot and need ducting/ventilation and I'm looking for a solid opinion... yes/no will i be dealing with more heat with one of them than this Blurple. I cant find anyone on here using one of these high wattage blurples... i see people using the old school ones with larger LEDs... mine has lots of little ones with green, yellow and orange diodes as well..

I'm really trying to clear up the heat issues. I have heard these newer LED panels (like mars hydro) have a lot more heat from drivers/ballasts and im wondering if I just got really lucky with this blurple...

Leds do not put out heat like hps. What don’t you understand? It’s the laws of physics.
more watts equal more energy which in the end. More energy equals more heat.
Leds drivers do run hot. Sometime to hot to touch. But never blistering hot. Fans are always recommend on any power source that warms up over 100+f.
Trust your light. Look thru the journals. If you have the watts to square footage witch is 35-40. You’ll be fine. Check your PAR if your worried. But if your plants are happy and temps are controlled. What do you have a hard time believing. If I’m understanding you correctly.

if you want to get a better cooling result , you can take the driver outside the light, the driver can be removeable.

I think a lot of people confuse heat with leds. Use a thermo gun and check Leaf surface temp. That’s more of an accurate readying of what your plants are enduring. My tents stay 79-86f. Even at 86. Leaves temp is low 70s. Heat rises. Cool air travels low. Use that to your advantage and the heat from the driver to creates a balance.

Agreed. Ambient temps vs leaf temp is much diff. My ambient temperature runs 78° while leaf surface is about 71-74°
People still think 1000w led means 1000w hid replacement? Lol. It's all about wattage. True wattage. That 1000w led prob runs 100-150 true watts @Antidote Man
If you wanna play with big boy lights you gotta figure out how to run at proper temps. Many marshydro fixtures have removable drivers so if heats and issue you can mount it outside the tent like we used to with old magnetic (even new digital) hid ballasts. Then you can run a heatsink or cooling fan over it to dissipate the heat.
The LEDs themselves make heat as well. You can't run high powered lighting without means of cooling whatever that may be.

1000 actual watts of led would push about the same as 2000watt hid in efficiency?

I am trying to prove that false, not that I was trying to when I bought the fixture, but somehow, with all of the information on this forum... I'm getting different results. I always assumed the same. You get what you pay for kind of thing. I've grown HPS and know the heat issues. I also see all of these new LED light bars and flat panel fixtures and assumed they were an upgrade to BLURPLE lights.



My light is the BestVA3000 at the bottom. 615 watts of actual light

The thing about it is that it has virtually no heat. And I'm not in a tent, I'm in a two door closet, probably 6 x 2.5 feet, using half of that to grow. I have one giant Romulan plant in it and I did have to bend it over, too close to the lights. 6-8 inches from the light they're fine. The two fans on top blow some air but not much. So far there are no heat issues and no exhaust aside form the open edges around the doors.

I believe I have paid the least amount possible for the least amount of headache for the best of quality buds. That's just what I believe from what I'm seeing here. I haven't yet used one of these LED upgrades, mars hydro, etc.

Highest quality light output plus least amount of heat issues. That's my idea.

I'm going to work harder to see if it proves correct..

Ok. Good luck then

Good luck with proving law the of physics wrong bud. Get your Nobel peace prize paper ready for that one.

I never said anything about proving any of that. I'm proving I can be lazy and put the minimal amount of effort in and get lucky enough to harvest quality bud without manipulating all sorts of other factors. Can the high-grade Blurple do it... We shall see...

Oh. My apologies. I mis read completely.
well good with that too.
