"is someone going to tell me you getsing a pound and a half to two poiunds off a 300w led thats supposed to be the same as a 1000w hps."

Yes, people REGULARLY pull 2g/w from LED grows. That means 300w dropping 600 grams, that's a pound and a quarter EASY.

Pinstripe's 2nd try: PC case + 22W LED - International Cannagraphic Magazine Forums - 22 watts, 38 grams. That's 1.727272 g/w. Assuming yield scaled linearly with power increase, a 300w panel in that person's hands should yield around 518 grams of bud.

Maybe 5 years ago LED wasn't worth it. Unless you attend every JEDEC conference you're going to be sadly out of date on your LED information - we've been getting 200% yields using LEDs with ALL sorts of crops, from wheat to strawberries, for the past three years already.

You can't measure a half-life of a diode, as alloys can't reliably have a half-life determiniation. The half-life only applies to pure elements in the chemical sense. Now if you're talking about SERVICE MAINTENANCE LIFE, 24/7 operation gives you 5-7 years. 18/6 about 10 years. 12/12 will get you from 10-15 years of service, and that is all dependent upon temperature control and humidity control.
khyberkitsune Reviewed by khyberkitsune on . Anyone switch from 1000 watt hps to LED yet? Was wondering if anyone from RI has made the move to LED. Interested in anyone that switched from 1000 watt HPS and what your results are in comparison. Thanks. Rating: 5
