I know we have a sticky, albeit, an outdated sticky, on lighting, but I also know a number of you have been doing experiments with LED Growlights. I'm in the market for 4 feet worth of growlights and wanted to know how you compared them to, specifically, T5 lights.
Currently, I have 2 foot, 4 bulb T5 fixtures (I talk about here), but I was curious to know if anyone had used any combo T5/LED fixtures (specifically this one), or pure LED fixtures and what their experiences were. I understand LED bulbs are very pricey, so I will probably end up waiting a few years before upgrading my setup, but the long life and electricity cost reduction are attractive to me. Thoughts?
