Nice fitting! Some years ago at a LightingEurope meeting I met the engineer who developed this system. It had quite a few innovations. By making the reflector unit fully sealed, the fitting functions as the lamp's outer jacket. Elimination of the ordinary outerjacket allowed the arc to be brought much closer to the reflector for superior optical control, allowing a 10% energy saving and reduction of the lamp power to 1800W. Both the lamp and the fitting were far more expensive than conventional systems, and normally this would kill the concept but the energy saving gave the customers a reason to invest. Moreover, another spinoff was that the improved optical control allowed the fitting to be made smaller, with reduced windage surface area, which allowed the use of cheaper and thinner pylons for carrying the luminaires, another cost saving. The result was a big increase in selling prices of lamps and fittings which made Philips incredibly profitable, with a net cost saving for the customer thanks to the cheaper mounting columns and energy saving. In all a smart move to see a greater share of the profits of the installation going to Philips instead of other companies!

And it seems that it is still the one and only system still widely to be seen world wide. No idea about the LED Arena Vision though....

Awsome fitting to have! I don't know how you get all your stuff in your flat Ahmet lol

When did they change the terminals on the lamps, from the early screw PFcFSc pins?

They had a LED equivalent on show at Light&Building in Frankfurt a few weeks ago. It was something like 90,000 lumens with a single monstrously sized driver of something like about 900W rating. You could tell they were planning for the failures already - both the LED "lamps" it contains and the driver have been designed for easy replacement

I think that was about 2005. If I remember rightly the wire terminals were introduced first on the 1000W SON-TD which was launched in that year.

That 1000W SON TD was only for weed growers IIRC?

Correct. A brilliant market. First sell an expensive lamp at an extortionate price that is affordable to these kind of customers, then the customer gets raided long before the lamps have done even a small fraction of the life, the lighting equipment gets confiscated and destroyed, and a few weeks later they are back to buy more!

Another superb money making idea by Philips lol!

90,000 lumens! , a tad short of the 150,000 original for the Arenavision!

600W SON is also 90,000 lumens

Ahh, but then they start talking about how you can see so much more clearly under LED lumens than traditional lumens In fairness the original HID fittings didn't have a very good light output ratio, so not all of the lamp's lumens actually made it into the projected beam.

LOL I have a huge storage Kev

I need to see picture of this huge storage!

well please wait
