Do you guys rec'd mars hydro 1600 watt led lights? sure are cheap...

His DE's are way to high off the canopy. I put mine about a foot closer and it makes all the difference. This is the only time I've ever seen led getting more than 2# per light, Imo this guy is getting paid from the led company. If leds were really doing this, everyone would be buying them by the 100's like they are with DE. I call bullshit. I'm going to buy one in the near future to see for sure and put up a journal

Which will you buy and test?
Would love to see your version of the same matchup.

Their not air cooled like yours, granted I still think he's running them a little high.....

I'd be skeptical of it too. Notice how the more regular members in this section will tell you commercial LED units won't beat gavita, but DIY LED can. It might not be more economical, but it can win in terms of efficiency if built right. Almost everyone is a liar in the commercial LED industry.

We keep getting shills from these companies coming and boasting their blurple shit lamps with overdriven and undercooled epistar leds, known to have extremely poor efficiency well below DE HPS, yet coming from all us DIY builders, just about all of us would suggest a DE HPS over anything prebuilt. Even the best LED prebuilt units barely tie with DE HPS in terms of efficiency. Why pay more?

DIY can win is lamp efficiency and umol/J dissipated, but even then, it probably won't save money in the long run. There's no doubt that it's straight up brighter though. No "perfect spectrum" tricks, just tons of white light. Commercial prebuilt units are almost always crap, especially if you think you're getting a good deal.

I`ve got a 1200w one I think its a mars it could be a "king" brand

anyway the 1200w draws about 600w and covers around the same area as a 600w in a cool tube that I have on the other side of the tent, it gives off less heat and all the light go`s downward unlike the hps

Personally I`d go with 150w or 300w cob led chips, get some drivers and large heat sinks, I`d get 3000k chips unless I was using more then say 4 or 6 then I`d get 1 or 2 5000k chips for every 4 to 6 of the 3000k ones

I`ve made a few nice 100w cob lights and I`ve got some 300w cob chips, heatsinks and drivers just waiting to be put together when the space I`ve got lined up for them is ready

if the 3000k`s look go when I fire them up I`ll be contacting the company in china that special ordered the chips from canada for me to see what else they have for my next project

DIY will get you better results but buying a pre made panel is a lot faster and easier plus you may even get a warranty lol

Those warranties are great for all the diodes that burn out on those shit panels. I wonder why they're so prone to burning out...

If it dissipates 600W of electricity, it's ultimately adding ~600W of heat to your grow tent, the same amount of heat a 600W HPS lamp produces and the same amount of heat a 600W MH produces, and the same amount of heat a 600W incandescent produces. 600W. 0.804613254 horsepower. (What weights more, a ton of gold or a ton of feathers?)

I'm not smart enough to contest that statement on a factual mathematical level but something doesn't sound right about that to me.
Power consumption can't directly relate to heat given off by a device (light) or a 1500w heater would give off the same heat as an a/c unit consuming 1500w - would it not?

It`s not true mate, infrared heat is made by hps lamps as their light is very warm around 2100k even a warm white led would be 3000k so forget for one min that the leds are mounted to heat sinks so the heat can be directed away from the plant and that the led is a 1200w that draws 600w because a 600w hps will draw close to 700w and a magnetic ballast will give off a lot more heat then a well balanced led driver will

then if you go digital on the hps ballast then crack it to super lumens your using 700w again maybe even 800w

An MH on the other hand gives off a bit less heat then a hps will but still more than most well made leds I`ve come across

Its light spectrum and efficiency but the extra heat could be why hps growers see faster results a lot of the time, till it gets too hot but also I find that hps`s cook the plants a bit more led buds normally have more smell to them once cured up then hps does

but that being said the 2nd layer or buds that gets a bit more shade always has more smell

So yeah 600w draw from 2 lights does not mean they will both produce the same heat that`s like saying a 600w halogen and a 600w hps will produce the same amount of heat

Hell 3000w heaters don`t all output the same amount of heat and there made to make heat



The Warranty is good for the led drivers, light elements burn out sometimes why would leds be any different if you use 100w to 1000w chips then you have less so there less likely to blow and if they do your just changing out one chip instead loads so bigger chips is my advice..... but that being said smaller chips are more efficient but don`t penetrate too well so its a catch 22

1W of infrared is as much heat power as 1W of green. Watts measure joules per second. What do you think that energy is converted into when it's absorbed and reemitted, then absorbed and emitted again? Even if you have a 100% efficient lamp, a 600W HPS lamp will still produce as much heat as a 600W 100% efficient lamp.

Even if you had a 600W 2% efficient lamp that output 2% microwave for every 98% waste, it would still ultimately produce as much heat as a hypothetical 600W 100% efficient lamp that outputs a perfect flat PAR spectrum. If you put 600W into a system, you're going to get 600W out in one way or another. Put your hand under one of these new white cobs (that have no IR), and you'll see how much heat visible light has.

This part doesn't make any sense so I can't really reply to it. Just no. Smaller chips are not more or less efficient than larger chips, nor does it penetrate worse. What is more likely to burn out is overdriven and undercooled leds, which just about all lighting manufacturerers do, even optic and area51 when compared to most DIY (2.1A vero 29? Try 1.4A or 1.05A.)

A 600W halogen produces the same amount of heat as a 600W HPS.

A 3000W heater dissipates 3000W of electricity to make 3000W of heat. Unless some of the energy is converted to movement, 100% of it was converted to heat. If there were losses in the power supply, that was also converted to heat. If your heater takes fuel, you will be sucking in cold air from outside and expelling hot air through the chimney, but you're still dissipating 3000W of heat.
