I think my deciding factor will be the life of LED's versus MH or T5. Seems that the upfront investment will pay off in the long run because I will not have to spend $$$$ on new bulbs every 6-9 months. How long will a good LED lighting system last? I've heard 10 years without changing them out. Seem like a long time is this is correct?
They also seem like a win-win because they don't put off as much heat. I will be going without a canopy and if I go with LED's I'm hoping to not have to buy a chiller.

The problem with LED is there are not many "QUALITY" pre-made fixtures available. Many do not have enough light or have wrong frequency of light for proper growth. There area few good pre-mades out there though and there are many people getting equal or better growth from DIY LED lighting also.
LED will be a higher initial cost but will be way cheaper in the long run, both in electric usage and bulb replacement costs. Just do a little research.
