Osram 18watt SOX lamp

Osram 18watt SOX lamp

Click to view full size image

Following a discussion a while back between myself, dor123, Skiller and Lantern-vision on the subject of, “is a superimposed 35/70watt halide ignitor too powerful for an 18watt SOX lamp”, here the result.
This lamp has had 1139 starts, over 3 years and a month on a 2.3KV superimposed ignitor, and to my suprise it looks hardly used.
It would be interesting to see one though, that has been switch started for the same length of time.

Yes perfectly, but I like to change my SOX at 12,000hrs, this won`t be wasted though, it will go in the one at my dads house when needed.

That looks excellent I agree! Looks pretty good for 12.000 hours anyway. You convinced me, a 35-70W MH superimposed ignitor seems to be just fine for 18W SOX.
I could imagine that using a starter or no starter at all (due to the lamp firing up with just the mains) could potentionally cause more sputtering during the first few seconds because it may be harder for the discharge to stabilize compared to being supported by an ignitor...but just a theory. Maybe there's no notable difference...?

By the way, do you know when this particular lamp was made?

That means it was made in January 1996 or 2006. As the first letter is not an "N" it is a genuine Osram lamp, not made by Philips for Osram. Therefore it should be 1996 - good quality lamp.

The middle two elements are the actual date: 6=1996 or 2006 (it cannot be older because before 1992 a different system was used), a=January. The first element is the factory code and the last element is always "8" and doesn't seem to mean anything.

Interesting, yes it is an Oldham, UK made lamp going off the discharge tube shape, I bought it round about 2007/8 and had it in storage for a year until its first use in JULY 09.

Not bad! I doubt an EFS600 (or even no starter) would significantly affect life expectancy though, unless these are likely to fail to strike when they age without a starter.

They seem to strike (and hot-restrike) instantly without a starter when new. My Philips SOX refused to hot-restrike once when I temporarily disconnected it for a few seconds to secure the cable but struck when I removed and re-inserted the bulb.

A standard 20watt 2 foot fluorescent choke, (small ignitors can also be used as optional, but not really needed).
