Osram Powertronic
« on: November 08, 2005, 09:50:28 am »
Hi all, I've just joined a few days ago. I have an Osram Powertronic PTU ballast for 70w MH lamps. I used it to run another brand of lamp other than Osram. The buzzing sound from the ballast was slightly different(louder) than when using Osram lamp. I am not sure if this will damage the electronics inside. Stated on the housing it says universal ballast for MH lamps. I have emailed Osram about the compatibility with other brands of lamps but they have not replied. Is there such a thing as a dedicated ballast for a specific brand of lamps?

It is possible to find ballasts for a specific brand of lamp - but not common.  The most usual area you find that is actually with White SON lamps, particularly Iwasaki ones, which used a bespoke ballast for their lamps, providing it with an extremely carefully controlled waveform.

I don't think this is normally the case with MH lamps though.  It's likely that you'll get the best performance/lifetime out of a lamp which is used with its respective ballast, but generally so long as the ratings and type of lamp are exactly the same, I'd expect it to work.

Ideal check: Go to the manufacturer's website for each lamp, and find the datasheets for them.  If their operating characteristics are the same, you know that they should work right.

Only thing I can think of is if the new lamp's a quartz style MH lamp, as the old was a ceramic type (or vice-versa), I cannot remember, but I believe these may have had slightly different electrical characteristics (Go take a look at Lamptech For more details there to prove or disprove my theory on that count!
