Well Just as many of you out there - I have been getting more and more interested in LED lighting. Skunky has been doing a small test and his results simply backup what others outside of GK are seeing. A couple notes from my research. If you are reading an article from 2012 or older - delete it - the technology is rapidly evolving. You get what you pay for. Stay away from inexpensive systems. They use cheaper LED (3 watt or less) and generally cheaper electronics. Wait for programmable systems. - Most of the systems out there have pre-set spectrum settings - someone elses idea of what I want for Veg or Flower. While this may work well - it is a hit or miss as there are no standards between vendors or products within a vendors line. These systems are not cheap - they are an investment that can halve your electrical usage and help deal with temperature as well. I would love it if we can use this thread to discuss the various vendor LED products out there so that I (and others) can share what we hav learned and make a more informed purchase. Specifically - I am looking for a programmable spectrum 500 watt (1Kw equivalent) unit using 5 watt LED arrays Anyone???
