Lumetek Digital Ballasts

So whats the deal with these new digital ballasts?

I would like to try one of the Lumetek 1000watt bllasts out, but it is hard for me to stray from my trusty Hydrofarm Lamps that have never gave me any problems for something so new and unproven, not to mention about 200$ more than a 1000watt Hydrofarm Radiant HPS.
Lumetek claims that their lights emit 25-30% more lumens then a typical HPS grow lamp. Plus the ballast is 5lb where as my Hydrofarm ballast are about 40lbs. They also claim to run so quiet you cant even hear them, that would be so much more stealth than the usual buzzing from any HID ballast. The coolest feature however is that all Lumetek Ballasts can run both MH and HPS bulbs. That intrigues me the most because I could run a MH every other light in the grow room to increase UV rays, and if it didnt work I wouldnt have wasted money on a MH because I could Just put the HPS bulb back in. I really like the fact that these lights give you that ability to change bulbs. It allows growers to use MH for veg. than switch to HPS at flowering. Like I said before you can also mess with the light proportioning during flowering to try and increase resin production. This allows us to try and mimic the sun much better when we can switch bulbs so fast. Also they are suppose toget as bright as they get much faster and claim to be efficent when it comes to using electricity.
I know there are so many more advantages and cool features with these new digital lights I havent heard any first hand experience with them. If I changed I would want to change all my lights which is 3 so I dont wanna drop 2grand without hearing some first hand experience. I really wanna know if they actually produce 25-30% more lumens. That would mean that 3 digital lamps would produce as many lumens as 4 of my Hydrofarm lamps. That would fuckin kick ass, it would increase yeild a ton. Also I am concerned that since this technology is so new that they dont have all the bugs worked out yet. I dont want to have any problems with them, I want something that works as reliable as my Hydrofarms. SO if any of you have one or have seen them in action and smoked bud produced by one let me know the real deal on these things. It sounds like they could give me a real advantage with the extra lumens and it running both types of lights.
