I don't think that it is so much the brand of the fixture but the bulb. There are bulbs that gets the job done, and then there are better and much better bulbs. Check out the different types of bulbs (light spectrums etc.) to find the best one for your budget and fixture. Hope that helps a little.I am going to start my first grow soon and I have most of the details figured out, but lighting seems to be disputed over so, In your opinion, which brand of hps have you seen the best growth with and is one 250W hps enough for one 55-65cm plant?
I run a Hortilux in my digital lumatek ballast, and it works great !!!Hortilux bulbs aren't compatible with digital ballast. A 250w is all u want for a tiny 2x2x4 ft area, and I imagine heat is still going to be an issue. I'd recommend getting the 250 HPS security light like you mentioned and take it apart, remove the ballast and mount it to a piece of wood and place it outside your box. Put your box over an AC vent… thats what I'd do.
That's not what the report said at all. What they did say is that "early" electronic/digital ballasts operated at such high frequencies that they created acoustic resonance within the arc (which literally shook the bulb apart and caused premature bulb failure). EYE/Hortilux has a vested interest in saying that stuff; they manufacture and sell "traditional" ballasts and overpriced bulbs. What the casual user should take away from the article can be found in bold on the last page of the report; "...our tests showed that the current electronic ballasts seem to operate lamps about the same as traditional magnetic ballasts. Energy efficiencies and light output are basically equal between the types with only the expected variation you would find in any group of samples..." I'm not sure how old that article is (there's no date listed) but I'm fairly certain (judging by the design) that it's at least three years old.Hortilux bulbs aren't compatible with digital ballast. <snip>
