I am wondering which brand currently producing the highest quality HID lamps? mercury vapors, high pressure sodium & metal halide etc.

The Philips seems to be all-china-made now:-X

Philips is low quality, and Eye apparently makes the best lamps available.

Eye lighting is by far the best. Modern philips lamps are mostly crap but I am not sure about osram lamps. (they are part of Sylvania which is the second highest quality lamps made today)

Trust me. EYE mercury lamps last well over a decade of high brillance. There's a strip mall near me lit with EYE 100w mercs. Almost none had to be replaced since I moved here in 2007.

...they are part of Sylvania which is the second highest quality lamps made today)...

Actually it is the other way around: Osram had bought the US part of Sylvania, include the brand name. So they are selling under Osram brand in Europe and Sylvania in the US.

The European part of Sylvania remained independent under the SLI (I think the SLI is the brand they are using now in the US market).

(...).. when we talks about quality control, Philips seems to be out of the question now

Should have take out Philips and put GE here instead, don't know how can I forget to put GE here, I have done plenty of searching for EYE Iwasaki HIDs  through online yesterday, even for the self-ballasted 500w to 700w mercury, only found a few which is rated 120V, wouldn't mind getting a step down transformers to run these.. Also, how much a does a 1000w HPMV magnetic ballast weight? it look well over 15kg to me..

I have had a hard time looking for a website that supplies everything I need, wanted to get them all in one shot and save up a little but on shipping cost, currently waiting for a price quote to see if they could send me a lamp with specific wattage along with control gears.  

@waterbug: Keep in mind that Philips in Europe isn't the same as Philips in the US at all. The quality of Philips lamps in Europe is much better than Philips lamps in the US. Since most of the comments in this thread (Except of Medved) are from american members that says how they see the Philips lighting products from their country, you can't yet reach conclusions that Philips lighting product are crap. Since Philips lighting Europe and Philips lighting North America, are so much different in the quality of their products (Not mentioning that they produces different lamps and gear for each region), I recognises them as completely two seperate companies. Philips in Europe, producing some of the world's best ignitors and HID electronic ballasts, which restrikes lamps much faster than even VS and Eltam Ein-Hashofet. Their electronic ballast (Even from China), restrike my Osram HQI-TS 70W/WDL within 4 mins, which Eltam SiP ignitor, restrike the Osram HQI-TS 150W/NDL of my Hostel (Not so different) within 9 mins.

Best HPS-  Sylvania
Best MH-   Sylvania
Best MV?  Don't know.  Don't use em. 

Best Fluorescent F32T8- GE, followed by Sylvania, followed by Philips. 
Best Incandescent-  Probably Philips or GE. 

In ceramic metal halide it is in my opinion Philips CDM-lamps made in Turhout Belgium

How good are Osram HIDs made in Slovakia ? (i have some HPS's from there, construction looks good, but i am not running a reliability/lifetime experiment)

Didnt know that, but really no surprise knowing how Iwasaki rock in what they do. Shame that we dont have any of their stuff impotred here (except specialised lamps for video projectors)

I can speak from my experience with the full-size (BT56) and cram (BT37) 1000 watt M47 metal halides.

Site spec's: 120 heads in parking lot, 480-volt fed, varying heights from 35 to 68 feet above lot deck. Photo-controlled through contactors controlled by energy management system. Typical pole has 1 or 4 heads, of which 1 burns dusk to dawn, remaining heads are burned at varying schedules based upon location in the lot. Lamps are provided by customer who has a lighting supply closed contract.

I will not recommend GE, especially those made in Hungary. They last less than a year, with some only lasting only 30 days if they even strike out of the box. The former contract supplier issued Sylvania lamps. 75% of those are getting to EOL now at 4-6 years of installation. I recently pulled a 8-year old Philips.

I will take (in order of preference):
Sylvania
Philips
Venture
Eye
GE (friends don't let friends buy GE MH)

You'd take Venture over EYE? Why? Venture SON lamps are absolutely woeful - are their halide lamps really better than EYE?

I am referring to the M47 1000 watt MH, in full size (BT56)and cram (BT37) lamp. I am speaking in my opinion and what has and hasn't worked well for my customer. I have found the last year's batches of GE are no good.
