Cool, a coated lamp! I wish they were just as common like the European ones.

I don't understand why coated HPS weren't used more in the U.S. I hear people gripe that they don't like HPS because of the glare vs a COATED MV lamp !

Unusual to see a BT bulb on such a small lamp.

I think coated lamps weren't popular because they produce fewer lumens per watt and the distribution of light is poor. Coated MV was used for function (higher LPW), not to reduce glare. But I do wish coated hps was more common. Btw is it true that even the reflector is plastic on these things?

I prefer clear HPS, clear most lamps really, as I like to see what's inside them. They're also good when precise optical control is needed. But coated lamps are better when in direct view, as they produce less glare.

@ Globe Collector : These were Sylvania's bright idea for a while They actually called it an ET-23 1/2 . I'm not overly fond of them myself. This was the only coated 150w lamp i could find at the time without spending a fortune ! @ streetlight98 : YES , the reflector IS plastic/fiberglass ! Years ago when I lived in Ct. there was a parking lot lit entirely with coated ED-37 400w HPS lamps and it was lit evenly and BRIGHT but without the glare ! @ sox35 : I agree totally ! I originally had a clear lamp in this fixture but changed it out cause the glare was messing with my eyes more than usual !

I just noticed the Barium Mirror Getter in the basewell.....don't see many with that, these days either, most have those zirconium-aluminium-cobalt pellets or strips. If this is an ET bulb, I should think about procuring one....are they available on E-Bay U.S.A.?

Those look nice, I'm assuming they are for US ballasts, wondering what UK ballast might run this..?

Yeah I'd think the reflector would melt from the heat. Maybe the durastar 3000 had an aluminum reflector? I cant see a 400w lamp not doing any damage to a plastic reflector.

There is 1 Durastar 3000 near me but it is too far from the fence for me to get a good picture of the reflector. I would ASSUME it still is all fiberglass including the reflector. BTW , I googled the "temperature rating of fiberglass" and apparently it begins to soften at 1500 deg. F and melts at 2050 deg. F !

Don't think the lamp would get that hot, well not outside the arc tube, anyway
