    Does anyone know what the benefit of having an electronic MH Ballast compared to a magnetic ballast?

    It's smaller, lighter, uses about 10% less electricity and costs about 10 times more than a magnetic ballast - i'd stick with magnetic's for MH and electronics for T5/8's.

    So the cost difference would not be justified?

    Caleb,

    This would depend on your view as to what you want to spend.

    An electronic ballast also has an added advantage in the sense that the heat generated is less than than of a magnetic ballast.

    So, if you were faced with limited space and don't mind spending a bit more , then electronic ballasts are the way to go.

    Pricing on electronic ballasts varies greatly , but they are in the region of R 1500 for a 150W MH ballast ( pricing for an Ice Cap MH electronic ballast).

    I have heard that the electronic ballast are more prone to damage due to power surges compared to the "older" magnetic ballast!

    I would say you could have a bit more than 10%, depending on wattage a manufacturer it could be as high as 35%, MH bulbs running on electronic ballasts generally also produce a better PAR rating than running off a Magnetic ballasts.

    The biggest down fall with electronic ballasts are their heavy price tags, as mentioned above.

    WRT power surges, I would say the electronic would be far more sensitive to surges than the magnetic types.

    but when it comes to electronics its worth alot more, more like R10 :)

    There is also up to 50% longer lamp life and 20% lower system power. This comes from Osrams PowerTronic info sheet. The ballast sells for about +-R500.00 for the 150W.There is also a 2X70W ballast around +- R100.00 more. Nice if you want to run 2 70W lamps

    Where in JHB can one get a decent Electronic ballast, or a decent magnetic one for that matter?

    no doubt that a magnetic ballast 150w rarely use 150w lol it uses more like 175w or even more! but an electronic uses closer to a true 150w average and gives of the same or slightly higher PAR so the electronic is much more efficient.

    so i agree with redhawk here.and if he's on with his prices then it means that the prices of electronic have come down ALOT and its probably worth it to go for the electronic instead of a R400 magnetic one.you sure that the price for electronic redhawk?

    Is there a quick way to check on the ballast whether it is magnetic or electronic?

    Yip im sure about the prices, I work as an electrical contractor in the commercial field, installed loads of MH Ballasts. Poiromaniax the difference between the 2 ballasts is, first size and weight. The electronic ballast generally is smaller and lighter than the magnetic.

    reason i ask is because i bought 2nd hand radiant lighting MH's and was wondering if the ballasts are electronic or magnetic.

    What sizes are they generally?

    By looking at the pic I very much doubt its electronic, AFAIK Radiant don't make electronic.
