600W LED Grow

re: GLH 600W LED Grow

im trying to understand cost benefit of using a 600w LED light. Is the 600w rating the actual consumption ... or is it rated in comparison to conventional lights?

I thought the argument for LED was much less power consumption ...or in other words ... under the radar of the utility company meters.


btw ... I'm enjoying your journal.

sorry to jump in...yes these are real 600w units..no "performance rating"
no there isnt a power savings.

yes no power saving it drawls 600w of power. so for it to be cost effective it would need to beat a 600w hps in the smaller foot print the leds have with less plants grown or equal the yield of a 600w hps while putting off less heat. or produce some real high quality smoke over HID.. IMO

I hope it does. how would you say they are doing so far Irish?

the best breeding book i have read was THE CANNABIS GROW BIBLE 2nd Edition by Greg Green. that book has allot of great info on everything buy real good info on breeding and different genetics.

Subscribed...gotta see how them LED's do. Every grower should have that book, it's in my library!!:nicethread:

My first post :)

I've been quieting tracking this grow (as well as botanist85's and some others) for some time, I just wanted to thank you Irish for putting all the time and effort into this grow as well as your past one (read every post) to help us all separate claims from reality.
Bring on the flower time! :yummy:

I hope Mike's product(s) will deliver both for the community's sake and his own successes, I can only imagine all the trial and error it's taken him and all the led folks to try and get these lights and spectrum ratios dialed on target for our crop of choice.

Also just wanted to express thanks to Mike of GLH for keeping the claims within reason, and being very responsive to the questions that are put to him on threads in these forums. Under promising and over performing is way better then the reverse given the led market prior to 2010.

From what I have read I think LED and the new plasma lights (barely on the market yet in Europe I read somewhere, 6k a piece) may be the future of indoor grows, we're just not there yet. Hopefully this grow and the associate products will aid in the next evolutionary step, taking led's out of the tiny niche and toward a more mainstream future.

One question I do have that I've not seen specifically answered or asked about these brand of lights (or most other led's), is the BTU spec on them. This may be a case of me being an idiot but should I just assume a straight watt to btu conversion on the order of the spectra 600 putting out around ~2050btu's, about the same as 600w hps?
I keep seeing the talk about lower heat out put, but in theory at watt for watt that can't really be true can it? I get the directional heat benefits angle, ie can be closer to canopy, but from an overall room cooling\btu heat removal standpoint there is effectively no difference (at watt4watt anyway) correct?.

Thanks again to everyone for sharing there hard earned knowledge.
 
re: GLH 600W LED Grow

The amount of heat produced by a lamp depends on how the lamp converts electricity to light. Some methods are more efficient than others and therefore convert more energy into light and less into heat.

nice post! and thanks for joining my thread, and reading my threads.

ive been very curios also about the question you asked? i wish i could say but ive only ran higher watt HID's in the past. i always wanted to know the heat temps on what a 600w hps puts off compared to this led light?
 
re: GLH 600W LED Grow

My thinking there is the heat sink is just a factor of efficiency in terms of removal\venting of the waste heat produced (much like a cpu heatsink), not so much in terms of the electric -> light conversion I wouldn't think, unless that efficiency is effected by temperature. But I'm neither a real engineer nor did I stay at a holiday inn express last night. ;)

its the heat sink or power supply right that determines it?

The quality of the power supply and other materials can be a factor. The materials used in each different lighting technology produce different amounts of various types of electromagnetic radiation; some visible, some not. The heat sink merely moves heat away from the chip - but has no direct effect on how much heat is generated.

Should be easy to calculate.

Measure your room and calculate the cubic feet, then divide the fan's cfm rating by that.

You can get some idea of how much the filter decreases flow by holding your hand at the exhaust side, connecting and disconnecting the ducting, and seeing if the exhaust flow diminishes much with the filter connected.

Even if I don't feel much difference, I subtract 25% from the cfm rating before dividing it by the room's cubic footage.

That will give you the approximate air exchange rate per minute.

The 150 is 438 cfm. That's some serious air exchange !!

These LED's produce so little heat you probably don't even need to vent it out ..and if you're growing indoors with them ... (obviously) the super-small heat footprint is probably welcome in a smaller grow cabinet.

they do produce heat and you need to vent your room out when using higher watts of leds. now when your using a 90w -180w the heat isnt bad when they have built in fans and stuff., but once you start going 300w+ you can notice the heat. but in order for your plants to thrive you need an intake fan with fresh air, or co2 and a exhaust fan to pull out the stale air. its a very bad idea to have a sealed room with no fresh co2 coming in and being vented out once used by the plants.
