LED LIGHTS THE ACTUAL TRUTH!

[Sativied]

Also, 100% of led is directed to the canopy. The ~ 50% reflected light from a hps probably doesn't account for much to the canopy.

Based on this, and quality led cobs, not 3w diodes, half the wattage is closer to fact than you realize

That's far from 'the actual truth' of course. With a proper reflector hood you can achieve over 90% efficiency at over 90% uniformity on the surface/canopy. You're basing your conclusion on the assumption that "~ 50% reflected light from a hps probably doesn't account for much to the canopy." which is grossly exaggerated, especially when using decent gear. (get a 'gavita IR' if you're really worried about light not reflecting properly)


Main argument of Dutch growers against using LED is the lack of heat is emits to the plants. We 'need' the warmth from the HPS about 40 weeks a year. When a grow gets raided the media+cops actually sometimes refer to the HPS lamps as 'warmth/heat lamps'. Besides the positive effect they have on lowering RH. It would require the opposite of a cooltube (very rare here) sort of, e.g. somehow use the heat from the LED device to warm up the air that is sucked in through the intake at the bottom of the grow closet/tent.

op here.. my point is still valid you can get an awesome grow with some cheap LED lights... okay maybe 50W LED is not 200W HPS but it beats using a compact florescent. its way way way cheaper than any other LED system out there and it would work just as good in a closet with some cooling of course...

 

[HolyGhost23]

AS far as what the OP says.. I think with most... including myself, just turn a blind eye to the nonsense of what is proclaimed...but if you are going to come in and bash LED lighting in a LED lighting specified forum then of course you are going to encounter opposition... the slightest bit of common sense would indicate that.


if you dont like the lighting method then fair enough... the question must still be asked why come into a led lighting sub forum?

EXACTLY PEOPLE!!!!!!... no matter how much you bitch an moan my point is valid and always will be.. avoid the bullshit kids but some cheap ass LED lights and get a good home grow..

AS A SIDE NOTE A CREE LIGHT MAKING 10,000LUMENS IS STILL 10,000LUMENS, IF YOUR HID LIGHT MAKES 30,000 THEN GET 3 50W LIGHTS!!! END OF STORY..its physics people now shut up and get growing

 

[Chronikool]

Your point isnt really valid when you make up figures on PRODUCTION output....

10,000 lumens per 50w = 200 lumens per watt... links please....

What? May I ask for a pic of one of these killer grows? Id like to learn from ya

Hate to nitpick, but you can only compare lumens to similar spectrums. You can't compare the lumens of say a 2700k and a 5000k source. They are different for sure.

and you shouldn't use lumens for anything really. They are clearly biased, using a radiometric or quantum figure is the best bet for every source.

there are tons if your search around here of people growing with the stupid par 38 lights. im sure a 50W honeycomb will do wonders.. it only take some self thought to realize that you guys are arguing nonsense.. and the truth is in the grows.. I will buy these lights or something close and start a grow to prove my words. im pretyty sure i stated that.. what you are doing is nit picking everything i say and trying to cause an argument.. for what i dont know maybe you have a small penis... but the point is.. im trying to show that you dont need to spend tons of cash to get good bud. im not saying its commercially viable.. hell if you want that go to plasma..

It is true, HID has a huge spike in the infrared and actually beams heat into the canopy, and the aluminum reflectors reflect that IR back into the canopy. Heat is an important consideration in any sizeable HID grow. Even in a basement in new england, heat is a limiting factor. Due to the high canopy temps, most growers use air cooled hoods which require glass. That glass is a major photon penalty and it collects dust and smudges over time (PITA).

HPS infrared also causes the plants to transpire more, canceling out any positive effect it had on relative humidity. To make matters worse, once the lights go out that relative humidity comes back with a vengeance.

(Top quality) LED allows you to pack more light into a given space than HPS but without the heat challenges. You can reduce ventilation which saves electricity and reduces noise. It also gives the carbon layer in the filters more contact time. Less heat also means you can grow more in less space, which can be a huge bonus where rents are high.

Just be factually correct in what you are presenting. That is why 90% of these types of threads have derailed in the last 2 years.

the reason we don't like cheap leds is because most of us have already used them. They fail sooner than later. Use twice as much watts and produce more heat to cover the same area as high end leds. Take a 3 year span. One a51 $500 or buy cheap leds that don't hold up warranties 3-5 times over that time $900-$1500. cheap leds are not so cheap now are they. Plus electric bill will be twice as much.

so you used a honeycomb style LED to grow before eh?...and you also say that I need to spend 500 bucks on some crap made with 70 cent LEDs vs 25 cent leds?... also you can not guarantee that a cheaper light will fail... as for twice as much wattage and heat vs high bin...its not that crazy, maybe 20% more efficient, you agian are falling to hype and nonsense..anyone actually sit down and test a grow with honeycomb style lights?

also for your so called cheap LED set ups.. were these ufo lights or home made set ups?..was it mono multi band or full?... please stop trying to argue invalid points.. if you spend 60 bucks on 100W's worth of light and get anything over 3 oz depending on electricity costs and other factors. id say the money was worth it especially if your like myself and live so far north that your only hope at an outdoor grow is with auto flowers cause the sun is on 24/7 for a month straight.

on a side note i bought some CREE 25W LED headlights about 8 months ago.. uses a 15W honeycomb for Low and a 10W for high beams.. and in the winter being that i get maybe 5 hours of sunlight a day they were on for almost 6 months straight with no issues.

that being said im gonna give it shot no matter what anyone says on here and ill post my results.. if the results are good (over 1G per watt) id like everyone to just accept the fact that when they spent 500 bucks on thier light they got fucked up the ass..

I used apollos from cidly and so has quite alot of other people. Almost every single one of them had failures within 6 months. They use knock off epistars and drive their leds to the max. The only reputable china direct company that drives their leds softer is evergrow. Their leds cost the same as an a51 at twice the wattage and same foot print.

again you fail to adhere to common sense to justify piece of shit leds. What leds have you used?

I guess a 'honeycomb style' is the 50w multichip yeah? 50 x 1w diodes?

Yeah i have used them. They do work...but you can get better...watch the heat in those fixtures...they run on the edge a bit...

1 gram per watt you reckon? They are about 42 watts actual draw so 1.5 ounces under one of those?....hmmmmm

Sorry op, I just realized your an asshole with that avatar. Don't take it down or censor yourself, but know that somebody needs a hug deep down inside.

 

[HolyGhost23]

if i can get better please show me.. the whole point of starting this post was to find a cheap efficient way to grow for less using LED lights IF YOU OR ANYONE HAS A BETTER SOLUTION, RATHER THAN BASH ME PLEASE POST LINKS!!!... put up or shut up.. anyone? have a cheaper way of getting just as much light using LEDs? for about the same cost

 

[HolyGhost23]

AS FOR MY AVATAR I GUESS GIF DONT WORK NO MORE ITS HITLER DROPPING A WATERMELON... I AM NOT A NAZI NOR CONDONE THE KILLING OF JEWS OR ANY MINORITY!!!..

i will change my avatar since it doesn't work anymore

Ummm ok you are a little all over the place here....

You talk about efficiency and cheaper light sources for the same cost as what? a 50w multichip?

 

[HolyGhost23]

well could you find a more effective light for 40 bucks? more efficient than 50W multi chip.. that is what im asking..

this goes to anyone.. if you can find a cheaper more effective light to grow with then please post here...

 

[Chronikool]

Ok....we might differ on what is 'effective' in that you want to grow some weed....however i dont think you really care at this point...

So just go for it....but remember to journal your results..

 

[gk skunky]

Are you talking about the CREE CXA COBs? That's the only thing I can think of boasting 10,000lm but pretty sure those are 100W. But either way. You aren't going to spend $100 and build a quality light. Not unless all you have to buy is diodes and still probably not enough. And I've yet to see a blackstar or any other "300w" 100x 3w diode panels you typically see in the cheaper panels compare to an area 51 or hans I r apache. Your best bet are Supras, stardust and some of the others diy threads. Seems CXAs and Veros are some good choices.
