Well said.

Also, if you're looking into buying a lighting controller (and you shoud be if running more than a couple lights), BUY AMERICAN! Stay away from the Canadian Hobby Boxes at NoWireNuts Canada -They have a major design flaw and have the potential to burn your house down or electrocute anybody who touches the box!
many retailers in this area have stopped selling the purple ones due to failure rates causing profit and customer loss. I have old purple ones and new purple ones they all have about a 20% failure rate

Nice post x,
electronic/digital ballast have come a long way and definitely have their place. I was really impressed when I saw the "innards" of the Eye Hortilux digi ballasts.
I must say that the Galaxy ballasts are pretty impressive too.
Due to the energy saving regulations, Energy-Star ratings, etc. there have been some serious improvements in the design and manufacturing of lighting products. Enter the economic debacle (theft of the worlds' economy by a handful of assholes - none of whom went to prison but were, instead rewarded) -Getting side-tracked: The decline in new construction that caused many electrical contractors to go under during the past 6-8 years, along with the incentives from the US government has created an opportunity for some to focus on retrofitting buildings with more efficient lighting and controls such as occupancy sensors, daylight harvesting, etc. (the stuff we used to do - like turning off lights that weren't used, opening the curtains on sunny days).
As far as grow lighting - we have seen advances in digital ballasts, LED has come a long way, Plasma & hybrid lighting shows promise, ceramic and pulse-start MH lighting become an alternative for grow room lighting but, through all of this, the old cap & coil HID lightiing technology emerging from the first low pressure mercury vapor lamps of the early 1900's to the MH & HPS lighting commerciallized in the 50's, not that much has changed.

I personally don't see magnetic HID ballasts in the grow room going away anytime soon. The lumen-per-watt efficiency is incredible @ 140lm/w
The theoretical lm per watt maximum threashold for LED lighting was surpassed a few years ago by CREE and thier latest R&D has broken their own 264lm/w barrier with 276lm/w on Feb 13th.
I've always said that when you see the streetlights around your town replaced with LED, it's time to start thinking about LED as a viable option for grow room lighting. That time is coming quickly but for now, the cost to performance of HID can't be beat when you take into account the actual cost of ownership and operation over the life of the product...

Another subject (State and Individual Rights and Freedom from an Oppressive Government):
Thieves and Whores from the DEA violated Washington State law when they committed armed robbery and armed assault against the owners and employees of several medical marijuana dispensaries this week. DEA has issues no comments about the raids but apparently they had 18 targets.
Medical mariguana dispensaries are easy prey for these cowardly thugs -They come in wearing their militarized costumes with automatic weapons pointing at the heads of unarmed civilians and call this "law enforcement".
They should all be taken out and shot.

Another subject +1, plus the original post was very interesting , thx
Check out the Ballast review that growershouse.com has done. It's very interesting considering the PAR output of these things. The Solis Tek ballast is what I'm going for. We'll see how long it lasts.
