Hi Chronic!
Well I have been running the "stock" SS-260 for a little over a year now and it has not given me any issues. I run in a 5 x 5 tent and currently have one SS 260, One SS-150 and two 100 x 3W custom white LED's. My yields have been awesome. The quality and density of the meds are fantastic. Here is a link to my journal.

I know that AMARE is continually researching and improving their products. They have top notch customer service and a awesome 5 year warranty. LED technology has been and will continue to get better/ It is based on Haitz's Law.You can't get around that. I don't ascribe to the "latest and greatest crowd". I am more of a if it isn't broke no need to fix it. What is important is the quality of the medicine for my patients. I left the HID camp sometime time ago and have not looked back. You can always find ways to improve a product. You don't see people walking around with those big old cellular telephones that were first made now do you? Then you have the "pick it a part crowd "5 W"
Who runs there car engine at full throttle all the time. You don't do it because you will trade off on longevity of that motor for a shorter period of time of more horsepower and torque. I have used their lights for sometime now and so have many others. The facts are plain and simple THEY WORK, are a Quality product and are very cost competitive and to top it off have GREAT customer service with NO BS... Keep it Green
