Okay everyone, Here is what I can tell you about LED Lighting from first hand exp.
1. Wattage!! The amount of watts per bulb is an extremely important factor in a good light versus a SUCK light!!! I don't care how many watts your total fixture has ... if it's made up of 1 watt bulbs ~ IT SUCKS!!! You get no light penetration from an LED fixture of 1 watt bulbs. 2 watt bulbs are good, but 3 watt bulbs are said to be best for ultimate light penetration.
2. Spectrum! Those who advertise LED Lighting for growing our beloved plants claim that the LED Lighting System has a very targeted spectrum which wastes no power, creates no energy signature, etc. etc. etc. My personal experience shows them to be quite lacking in actinic blue as well as the intense ultra red provided by HPS. Also I found my girls to be much more prone to infestation whilst using only LED Lighting. Crazy gnat outbreaks & spider mites galor!!!! AND constant fighting with nutrient balance, pH, nitrogen burn & issues I have never encountered in 30 years of growing. Example, leaf appearance became palored. Each leaf section was green-tinged-yellow with dark green outlines. I thought "Over watering" ... nope. It was light deficiency!!!!
***NEVER USE NEEM OIL if you use LED Lighting. It will burn the crap out of your plants & I am ultra conservative with applying any type of chemical to my babies. The test run of 1/20th the suggested dose almost wiped out my entire crop from chem burn.
I have 6 ~ 120watt LED fixtures (2watt bulbs); plus 3 ~ 90 watt UFO LED fixtures (3watt bulbs) & after 6 months I could no longer take the absence of HPS lighting. Following the addition of HPS ~ my problems are vanishing one by one.
I would suggest using at least half of your total LED wattage in HPS. I have added 4 ~ 150 watt HPS fixtures to my 990 watts(actual) of LED Lighting.
...On the other hand ... my roses love em!!!
I hope this helps answer some of the questions for this topic.

I was hoping you would respond to my post. I did massive research prior to purchase and when I saw the companies you posted I wanted to reply. I purchased from cfnproducts ~ posted on ebay but not a lighting company. I had read so many horror stories and so many fairytales ~ all regarding LED. Still it was very appealing if the proper lights were bought. My lights actually do fit the your description of good fixtures, 5 Band, state of the art, in country with good warranty and customer service, & all just released in the past year. As I said ~ never have I had any of these issues with HPS. I truly feel there is a spectrum deficiency, and perhaps you are correct, maybe my particular lights are the problem. I did have one strain that grew very lush (Indica/Chem 24) but none others (mostly Sativa/lemon lime). I'll admit ... I have been racking my brains over the issues resulting, so if there's a trick to LED growing I'm all ears. I'm definitely going to keep using them, & since I added the HPS back into the mix things are returning to normal. Your response is truly appreciated. Thank you

You are correct about the cut corners. After further examination per your instruction I did find that there were no fins only flat sheet of metal inside. The cords are removable on the 90 watt fixtures but not the 120's. I went to Advanced LED and looked at the spectrum charts for their fixtures and it definitely confirms the lacking blue & ultra red spectrums in the lights I have purchased. Again I thank you for your input. It's difficult to get good advice these days.
