Can you tell why the ballast for MH bulb is so expensive (reaches even a 100 bucks)?
Here is one for 29$

the expensive blasts that are above $100 are electronic balasts for a special type of MH bulbs. if you think it is expensive, check out the ballast for 575W HMI bulbs. The cheapest ones are above $300 (if you can find one at all).

Like TV sets, you can get one under $100, you also can see some $5000+. ( it is not appropriate comparison, but you get the idea)

Yeah, accidently posted the same link twice insted of this one, and one for the more expensive ballast, but you got the idea...

18wheeler - thanks for reply, but my question is what's the difference , i.e. why is the expensive ballast does a better job? What'll happen if I'd want to save some money, and buy a cheap ballast? Where will I feel the difference? It's for a special MH bulb - like what bulb? Is that special bulb gives more lumens? Will the cheap ballast work with, let's say, a standart philips bulb that costs about 30$?

Can someone please tell me, how this

ballast is better than this one:

Please explain me, what do I get with the better one, which I don't get with the cheaper one? (I want to know in order to decide which one will fit me the best)

The first one looks similar to the one I just got.All I did was take it out of the large case it was in.

The big difference was the fact I only paid $25 plus shipping for mine.

Heres the auction link.You might want to contact him,he had 6 when I won this auction.
