I actually have free electricity at my office, otherwise I'd run the numbers to see the cost savings. 5x longer lifespan ... I'd want an independent review.
Oh wow those are very good prices. If they perform well (or even half of what they promise), then yes these will give the upmarkets ones a run for their money. Of course the same can be said for almost all goods. I'd love to have time to experiment with an indoor aquaponics garden in my basement, and try out various lights.
