View Full Version : What is the main trend of the ballast?

I know that in Europ, such as Netherland, 1000W is the trend. And also, the 400V ballast (3 phrase) is the trend ,because the higher voltage it is, the lower the waste is. May in north American the market have this trend? The 240V have its advantage?

Why many ballast with switchable voltage? 120V/240V? The main voltage of the green house in the north America is 120V,is not it?

the dedicated voltage is better than switchable voltage?

Hello, yes you are right more and more Europeans are going with the 1000W, from their 600W systems. But, the two are still far apart in sales, with 600W dominating that market. 400V will reduce the amperage a system will run, but the reason our hobbie market doesn't gravitate to higher voltage is the safty factor. With 120V and even 240V getting zapped will result in for the most part a good scare (unless you lock on). While 400V and 480V will likely result in major harm or even death. So the higher voltage is usually left to the commerical lighting market. The voltage switchable feature doesn't affect the systems effiecency at all, since the ballasts we use are quad tapped (120, 208, 240, and 277V) the ballasts runs on any of these, we choose to wire up the 2 most commonly used voltage. The higher the voltage the less the amperage, and the only measureable benifits of running higher voltage is the ability to run more lighting systems on a curcuit. One other benifit is the transformer tend to run cooler with the higher voltage.
