Thats the difference between crap lights that will fail or perform poorly and proper engineering and that's why it pays to do some research. It's all those things that helped me make the decision when I ordered my ISIS and Magnums. Same set up as Spectra and Stealth Grow, finned heat sink, LED's mounted directly to heat sink, fail-safe wiring to stop individual LED failures from crashing a whole spectrum or row. They also have the added bonus of delayed start up circuitry to help with heat control in case of power flickers. It isn't a huge issue but I liked it. I used to wire the same set up into contol panels when I did the 9-5 thing and in my opinion as many safeties as you can get just saves headaches. Plug and play power supplies instead of hard wired (super easy to change if there is a failure). Seperate power supply for fan circuits.Spectra lights have a 5 year warranty and they've been proven to grow all over 420magazine.com They put a lot of work into extending the life of these lights too. Finned heat sinks, no PCB board LED lights sit directly on heat sink, LEDs running at the right wattage for grow power and longevity/heatlevels. They also have fail safe bits so if one LED dies it doesn't take out a whole row or column, and supposedly its designed so LEDs can be easily replaced (but I'm not sure if we can order those bits ourselves?)
The website is slowly getting updated, pictures are out of date, here are what they look like now (you can see the fail safe bits too) http://www.420magazine.com/forums/journals-progress/132192-irish-boys-480w-720w-grow-led-hydro-land-clovers-49.html
As for the selectable spectrums. I think that's just a preference. Not sure if I'll use them that often but nice to have the option. On the Purple Kush I'm vegging right now I killed the red for a while to get them to bush out. As for failures, it's just a manual switch like the light switches on your house so nothing electronic in there to fail.
In the end budget is a major constraint for a lot of people and the cheaper panels give them an option to avoid the issues of HID. When I first was on disability I bought a Saturn, it was all the budget would allow and it got me to physio and managed to live for exactly three months after the warranty expired
