What do you guys think about these LED 6500k lights

[SuperTorch]

It seems like these would be very effective with a indoor grow if done right. The key factor here being the electricity co wouldn't know anything was up at the very low wattage, at even 200 watts worth, these would be more than enough. They look like they could save some money over the long haul too, as they'd cost about $2.00 a month comaped to $30+ on the 1000+ watt systems. Just curious what the greenthumbs think about these. I know they are a little weak but youd just use multiple lights to get your lumens to cannabis growing specs. Plus the heat output would be far more manageable.

I think the time will come when LEDs are the preferred way to grow plants. But I don't think that time is here quite yet. Give 'em another five years to boost output. Still, if you want to be on the forefront experimenting with LED grows now, more power to ya!

Super, I'm not a lighting expert or anything.
But I'll say this:
LED's do not produce enough light, now I mean than respectively:
Yes, a led will enable you to see something.
However, it does not produce NEARLY enough lumens to keep a plant going, plus what spectrum is it in?
From veg to fert some people change the bulbs to feed the plants the right spectrum.
So are they red or blue based?
Basically: I think its a bad idea, plus the plants will stretch to reach them.

Well lumens can be increased by just adding more of them, I think they tend to be in the blue spec, but they are closer to 6500k9Daylight) than anyother lights, that I know of. If there is not someting inherantly wrong with the type of light a led produces then everything elest could be caculated out to specifications for the size of the room, also I'll say again heat from the bulbs would be very very low only 1-5% of typical bulbs. I'm just asking and don't know that whay I posted I know a true green tumb can tell use yes if its BRIGHT enough then they would be good.

Well, a 1k light with a decent bulb puts out around 150,000 lumens of nice plane-useable light. Divide 150,000 by however many lumens those LEDs put out, which is 200 lumens (for $60). So to equal one 1k light would take 750 of those $60 lights, or $45,000. And it still wouldn't be as efficient unless its spectrum were as good as a Hortilux or something on the 1k light. You could probably get by on a third of those lumens, but still, that's $15,000, and 250 LED bulbs. Heh.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I don't need to reply lol

[jamstigator]

Er, I meant 'plant-useable' light. They need to make keyboards for stoned people! ;)

150,000 lumen or candle power, I know your right and at that much cost it a mute point. But I have a 3 watt led that puts out 80 lumens and its just as bright as a regualr flash light even more so. These are very cool to and any one who has bought one far a Mag replacement has been BLOWN AWAY.

I hear you it looks like LED still need to evolve.

This website gives great reading on how much output the better 3+ watt leds are produceing

http://www.flashlightreviews.com/index1.html

they have a review of tons of lights check out INOVA Brand, the LED Mag lights are not as good as the one I posted above but still show how for 24 hours+ they burn brighter than the regular bulbs and don't drop in brightness like the standard mag does. 3 D cells here last forever compared to standard 3d maglight.

Of course anyone who knows anything about lights knows that lumens have nothing to do with growing plants.

Try looking for a PAR graph to see what the output range is in. I would like to see an experimental grow done with LEDs though.

Plants use PAR. People use lumens.

[jamstigator]

PAR is a subset of lumens, the fraction of the available light (luminosity) that is useable by plants (e.g., that falls within the favorable spectrum). In that respect, it has very much to do with growing plants.

If you have a light that generates 100% PAR light, is that better than a light that only generates 30% PAR? If lumens had nothing to do with growing plants, then the answer to that would always be 'yes'. But the real answer to that depends...on the respective lumen outputs of the two lights being compared.

I would like to see an experimental grow done with LEDs though.

Definately, could change the whole growing scene if they work.
