Well, the cheap way is to go to crappy tire and pick up some high pressure sodium
and mercuty security lights. The yellow of one cancels the blue of each other.
Or buy used gear. Craigslist.org and ebay is full of failed (or paranoid)
hydroponics setups and if you're careful and patient there are some good
deals out there.
Also check places that reccycle industrial fittings ("green stores")
as shops sometimes refit entire buildings and the lights sometimes show
