Led Lights... How Much Heat?

[hotshotisdashit]

I was wondering how much heat do led lights really put off. I do know that it may vary for different lights. But im speaking about the top lights available right now... Apache tech, area 51, go green, cobs etc. I have used the solar storm 880 but it does produce quite a bit of heat.ooking for 1000 watt equivalent in a 4x4 or 5x5. My 1000 watt hps raises.y temps about 10 (goes from 74 room temp to 82-86) degrees easily. Even though its air cooled. Looking for something where i wont have to use an air conditioner. Give me your opinions or what you use

Heat is heat. I use 800w of LEDs Vero29's with a coolhood style build. I think some guys on here build some good ones. Anyway I pull around 100 cfm through the led hoods which keeps the area 6 deg above ambient 6 or 8 inches below the 8 LEDs. See the avatar.

Hard to give an answer in black and white. Cheap LED's tend to put off a lot of heat

Heat issues are very important to me. Its the number one reason id be willing to spend that much on another led light.

LED lights that are highly under-driven are more efficient and thus less loss in the form of heat

In a Michigan Basement, I have to use a CO2 Burner this time of year to heat my 8x10 room with 800W of COB/Kessil LED. The Kessils do put off a little heat, but not very much. Without the burner, I was barely able to get up to 72deg. This is going to depend on a couple factors such as environment. It will depend on how efficient your parts are, and how much energy they're using that becomes heat. As @Dumme said, there's no easy black and white answer to this.

 

[hotshotisdashit]

Much of this is well understood. But im looking for the leds that are the most efficient and run cool. Give a brand you know and/or use that you think will fit this criteria.

 

[hotshotisdashit]

Hockey mention cobs and kessil.

Are you looking for a DIY set of components or prebuilt plug/play setup?

 

[HockeyBeard]

Most efficient and run cool = Top BIN COB under driven, built yourself.

This is what I was leading to
CXB3590 in 3500K or 4000K are the most efficient that will still yield the best growing results from everything I have seen/read

 

[HockeyBeard]

4000K is most efficient, but 3500K will probably produce a better flowers. If you're using the same lamp veg through flower, I'd go with the 4000K, otherwise, the bit of extra red will help flower production

In the near future i plan to do a diy cob panel. But not really sure on what ill need, have to to etc. Itll be my early spring project. But for now when my tax returns are back ill invest in a premade light.

 

[hotshotisdashit]

@Bass and hockey... Ive been hearing a lot about cob lights with vero and cree lights. There are also some premade lights with these lights ie. Area 51, go green, optic and heaven bright to name a few. Big ups for the guidance.

There are a few premade with Cree CXB cobs, and thee are others with The Vero 29 like the Area 51 you mentioned/ Anything with what you mentioned that also uses Mean Well as the drivers is worth a look.

Take a look at Onyx LED as well then.

Same here with low temperatures in the basement. I'm not hitek such as co2 but I like the purple colors the low temps seem to trigger.

Johnson lights is another.

Yeah, I need to put the thermometer on the outside of the room so I can get an idea of what the temps are during the day. But, I think I should be getting down around 70. I'm just gone all day at work and don't really know the ambient temp of my basement at night (which is day). I know the floor is a cool 65 degrees though (the temp gauge was laying on the ground for a few minutes )

Ive looked into their indus series. Its just so many options ti choose from.
