What do you guys think about these LED 6500k lights

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

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.

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.

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